ED-E My Love

 is a quest in Fallout: New Vegas.

Quick walkthrough
Talk to Johnson Nash in Primm or Thomas Hildern in Camp McCarran about ED-E to receive this quest. Once ED-E has become your companion, speak to Old Lady Gibson at the Gibson scrap yard to hear a recording made by Whitley, an Enclave researcher at Adams Air Force Base. He is sending ED-E, a special prototype for a combat Eyebot, to Navarro for further upgrades.


 * 1) Recruit ED-E in Primm.
 * 2) Speak to Old Lady Gibson at Gibson Scrapyard, Michael Angelo on The Strip, or Doctor Henry in Jacobstown to trigger Log 1's message. This message can also be triggered by talking to some of the people in the room with Lorenzo or speaking to a non-subtitle/non-coversation brother hood of steel soldier(unsure but worked with me).
 * 3) * If you have used all the dialog options for Old Lady Gibson prior to recruiting ED-E, you cannot continue the quest with her.
 * 4) Wait 9 (or maybe only a couple) in-game days.
 * 5) Speak to Ignacio Rivas at HELIOS One, Michael Angelo, Thomas Hildern, orDoctor Henry, or Quartermaster Mayes at Camp Forlorn Hope to trigger Log 2's message. This also triggered when the terminal in the front lobby is accessed to learn of the Archimedes Project and then subsequently talking to an NCR guard further back in the complex.
 * 6) Wait 2 in-game days
 * 7) Talk to ED-E to hear Knight Lorenzo's message. Immediately following the conclusion of Lorenzo's message, April Martimer will cut in and make a counter-offer on behalf of the Followers of the Apocalypse.
 * 8) * If you have completed Classic Inspiration for Michael Angelo and exhausted his dialog options, you may not be able to use him to obtain ED-E's messages.
 * 9) Decide whether you'd like to upgrade ED-E's weapons (FoA) or armor (BoS).
 * 10) * WARNING - Empty ED-E's inventory before handing it over to the FoA or BoS; otherwise, you will lose all items in its inventory.
 * 11) Take ED-E either to the Mormon Fort in Freeside to upgrade its weapon, or to the Hidden Valley BoS Bunker to upgrade its armor.
 * 12) Wait 4 in-game days, you will get a message saying "ED-E has returned to Primm". He should approach you upon re-entering Primm. Either that or he will be in the Nash Residence.

Notes:
 * The actual number of days between the steps listed above is either inaccurate or not static. However it appears that the number of days listed above is the medium of a possible range of days required.
 * OPTIONAL: Go to REPCONN Headquarters and recover mission tapes from the dead BoS patrol.
 * In order to talk to ED-E and listen to the message from April Martimer, you may have to go back to Novac after obtaining the mission tapes from the BOS soldiers. At first, if you don't return to Novac you will only have a quest arrow pointing you towards Hidden Valley. In some cases, you might have to discover Hidden Valley if you have not already done so.
 * On PC, Xbox 360 and ps3, ED-E may start the Lorenzo message with no prompting (ie: you don't have to initiate a conversation with ED-E). The message from Lorenzo is odd in that part of it is with one male voice with a distinct "radio" sound, while one section is obviously a different male voice (yet, supposedly still Lorenzo), without the "radio" sound effect, and the audio doesn't exactly match the text on the screen.

Detailed walkthrough
ED-E's keywords can be triggered through old conversation as well as new.

Obtaining ED-E
Get ED-E in Primm in the Nash residence, the building on the right hand side after walking into Primm from the broken bridge and moving straight ahead until you see a dead courier, the courier is propped up against the house.

To fix the robot you need either 65 repair skill, or 55 science and 35 repair skill, or you can fix it with spare parts (you need 1 scrap electronics, 3 scrap metals, and 2 sensor modules).

ED-E
ED-E was built by an Enclave researcher. It contains research data as well as voice recordings from Whitley, an Enclave researcher. Unfortunately, ED-E has seen better days. The damage inflicted upon it has made accessing that information troublesome. Luckily, playback of the voice recordings can be triggered if ED-E hears certain keywords spoken by NPCs you meet in your travels.

Playback Event Triggers
There are two pre-recorded messages ED-E needs to play back before the quest can progress. Triggers usually occur while talking to someone who used to be in the Enclave, or who talks about the Enclave, or who talks about important technology. So far these events have triggered playback, more will follow when found:

Log 1: "Subject E: Diagnosis complete. Begin Recording.  My name is Whitley..." (the message continues).

To trigger this message, do one of the following: Log 2: "Download complete. Begin recording. Navarro outpost scientists, ..." (the message continues).
 * Talk to Old Lady Gibson at Gibson Scrap Yard. NOTE: If you've already gone through her conversation options, you will have talk to someone else to trigger this message.
 * Repeatedly talk to an NCR Trooper standing outside of HELIOS One. You can also gain the HELIOS One quest, and talk to several Troopers inside to trigger Log 1.
 * Talk to Doctor Henry at Jacobstown about his experience with the Enclave.
 * Talk to Colonel Moore for the first assignment in the quest in For the Republic, Part 2.
 * Talk to Ignacio Rivas at Helios One about Archimedes II and The Brotherhood of Steel
 * Talk to Torres, the quartermaster of the Brotherhood of Steel armory in Hidden Valley.
 * Talk to Michael Angelo, the maker of the New Vegas neon signs in his shop next to Vault 21.
 * Talk to Thomas Hildern, director of the OSI at McCarran.

To trigger this message, wait five in-game days after triggering the first message then do one of the following:
 * Talk to Ignacio Rivas in the NW corner of HELIOS One near Fantastic and ask him about ARCHIMEDES.
 * Listen to the brotherhood scribe teach his class.
 * Speak with Veronica Santangelo while on the quest I Could Make You Care and after accessing Father Elijah's terminal.
 * When trying to gain the Brotherhood of Steel trust (without the help of Veronica), a keyword is spoken after killing or convincing the NCR ranger to leave Hidden Valley.
 * When you first talk to Michael Angelo on his workshop at the New Vegas Strip. Talk about his "lack of inspiration" and choose the medical answer. (It will still work even if the requirements aren't fulfilled).
 * Completed Still in the Dark, leave Bunker L1, and return again. A BoS Scribe will say something thanks you (and a footlocker (re-spawn, 00161f77) contain energy ammo will appear in front of two BoS Solider). If you try to talk this BoS Scribe again, ED-E will immediately play the message.
 * Talk to Quartermaster Mayes at Camp Forlorn Hope about locating supplies sent from Helios One for the Restoring Hope quest.
 * Talk to Doctor Henry at Jacobstown about his previous employment with the Enclave.
 * Talk to Watkins about her parents and her decision.
 * Talk to Dr. Hildern at Camp McCarran about the quest There Stands the Grass.
 * Sometimes just hanging around with the Brotherhood of Steel in Hidden Valley will trigger the event.
 * Talk to a Brotherhood of Steel paladin around Hidden Valley and they will proclaim they haven't seen this type of eyebot before and it will trigger.

Unknown Log 
 * Talk to Senior Knight Lorenzo in Hidden Valley.
 * Talk to Quartermaster Mayes at Camp Forlorn Hope about retrieving NCR Dogtag.

Additional Notes

 * The logs can be found in almost any order, such as finding Log 2 at Jacobstown instead of at HELIOS One.
 * Other possible keywords have been reported as being: Enclave, Navarro, Poseidon, Helios, and Archimedes.
 * If Lorenzo has already been killed as a result of Mr. House's The House Always Wins (Part V) waiting two days after talking to Ignacio Rivas and talking to ED-E will trigger April Martimer to contact you without having to travel to the REPCONN Headquarters.
 * A way to incorporate another companion to help in this is to have Arcade Gannon present, as his personal quest being undertaken will result in many of the key words being spoken.
 * Using the "wait" feature will also speed up ED-E's speech events. Use the wait feature in increments of 1 hour inside Old Lady Gibson's house and after that anywhere else in the world.
 * It is possible to get both Logs 1 and 2 from Doctor Henry in Jacobstown.

Conclusion and Reward
Two in-game days after the second recorded message is triggered, Senior Knight Lorenzo of the Brotherhood of Steel will contact you through ED-E.

"Uh... Hello. Hi. Are you there? ..." (the message continues and ends with a russian janitorial voice-over as a placeholder for Lorenzo)

If you already completed "Still in the Dark" mission, following step will jump to stage 5 and 6 (two object in world map). It will skip stage 2,3,4
 * He goes on to say he'd like to examine ED-E and wants you to bring it to a patrol near REPCONN Headquarters. Head there and proceed to the 3rd floor.  There you discover that the  Brotherhood Scouting party has been killed.  There is a Holotape note on one of the dead members.  Immediately after you acquire this note, you will be contacted by one April Martimer of the Followers of the Apocalypse.  She is located in the Old Mormon Fort (just inside Freeside's North Gate) and would like you to bring ED-E to her instead.  The person you choose to take ED-E to will determine the outcome of the quest.


 * April Martimer will NOT contact you until you have discovered Hidden Valley.

WARNING - Before you hand over ED-E you should remove everything that is in ED-E's inventory, for you will lose it all! If you have had ED-E Wait outside the bunker, he will be gone as soon as you tell Lorenzo he can keep him, and you will not get a chance to recover anything from ED-E's inventory. IMPORTANT NOTE: you can get your items back through the console, first enter "prid 1732d1" and then "OpenTeammateContainer 1". Obviously this only works on PC, but it is confirmed to work (this is also below in the bugs section but I feel it needs more emphasis here).


 * If the Brotherhood examines ED-E, ED-E will get a defense bonus (DT: +8). Also, ED-E will have the bumper stickers, rust and dirt removed, revealing a shiny metallic surface.


 * If you take ED-E to April Martimer she offers to upgrade ED-E's weapons (2 non-critical shots to kill a coyote (normal difficulty) as opposed to 3-4) also ED-E will have the bumper stickers removed and his weapon will change.


 * Either option will not affect the PC's standing with the the Brotherhood of Steel or the Followers of the Apocalypse, so the choice purely weighs on what bonus is more imperative to the player.

Whoever examines ED-E will require 3-4 days to do so and you will lose ED-E as a companion during this duration. When ED-E is returned to you his inventory will be reset, so it would be wise to clean out his inventory before giving him up for the few days. When the wait to get ED-E is over, the quest advances and a message will appear saying you can pick ED-E back up in Primm to complete the quest.

NOTE: It is possible to be contacted by Brotherhood and the Followers without obtaining all three logs.

NOTE: It is possible to skip the REPCONN Headquarters scouting party rendezvous portion of the quest entirely if you have already discovered Hidden Valley and accessed the Brotherhood Bunker (such as by breaking in or traveling with the companion Veronica.

NOTE: It is possible that during Senior Knight Lorenzo's transmission through ED-E his voice will change to a voice with a harsh russian accent.

Bugs

 * If you talk to Old Lady Gibson and go through all the dialog before you have ED-E, she will no longer trigger the log. Go speak with Ignacio Rivas or any NCR Trooper outside HELIOS One instead. Alternatively, issue "setstage 001572E8 10" command in the console to reset.
 * Talking about Archimedes II without having ED-E seems to cause problems too, going back after getting him doesn't trigger anything.
 * Note after completing HELIOS One, if you return to Ignacio Rivas with ED-E in tow, if you ask him "why are you still here" then ask him about Archimedes again, the game will crash when ED-E's quest log updates. -(Xbox 360)
 * ED-E seem to have an internal cooldown on the input words, needs to take a day or two before you can advance in the quest chain.
 * If talking to Ignacio Rivas doesn't trigger the next log try going to Jacobstown and talking to Dr. Henry about his past as an Enclave Scientist.
 * It is possible to resolve issues with missing dialog using the following console command: setstage 001572e8 10
 * Doing so appears to disable Steam achievements until you reload the game, however.
 * I tried this and it didn't initiate the log, however addscriptpackage 0015882d then evp, after clicking on ED-E in the console did trigger the first log, the package for the second log is 0015882E if anyone wants to try that one.
 * Even if Old Lady Gibson is dead, speaking with other NPCs around the wasteland can still trigger ED-E. VERIFIED: This player murdered Old Lady Gibson before he ever heard of ED-E; quest began and logs were triggered by Ignacio Rivas, then Thomas Hildern, with no problem whatsoever.
 * Handing ED-E over for upgrades (Tested with Both Factions) destroys everything in his inventory. (VERIFIED: ED-E's inventory is empty when it returns to you, regardless of what it was carrying.)
 * This is because the ED-E that goes back to Primm is actually a different npc, with a different ref id.
 * you can get your items back through the console, first enter "prid 1732d1" and then "OpenTeammateContainer 1", this will open a trade window where you can get your stuff back from his inventory after the upgrade
 * Occasionally your items may be restored to you if you ask ED-E to wait, leave the area and then ask him to rejoin your party. (Xbox 360)
 * If you repair ED-E before talking to Johnson Nash he may not give you the quest or tell you what to do next. Visiting Old Lady Gibson at the Gibson Scrap Yard will trigger the quest and the first message needed.
 * Should you get stuck, the messages can also be triggered via console. "setstage 001572E8 10" will trigger the next message, but you have to wait for about 2 days after each messages as there is a cooldown for them to be triggered. (The console will show a note of the time it was triggered last when you use the console command)
 * If taken for weapon or armor upgrades, ED-E may 'crash', not following the player or attacking at all.(xbox 360) Can be fixed by terminating companion protocol, hit return to base, then talk again and recommence companion protocol. (PC)
 * If you retrieve the password from REPCONN BoS Soldiers before being contacted by Lorenzo you will not be able to validate the passwords in the quest, making it unfinishable (X360) (Seems to be fixed in Patch 1.2 on PC). This can be overcome by using the console command: player.additem 0015d9db 1. This will add the relevant BoS holotape to your inventory so you can progress the quest.
 * After obtaining the quest Can You Find it in Your Heart?, Ranger Jackson might attack ED-E if he is one of your companions.
 * After turning ED-E over and waiting five days, a message said that he was back at Primm. When I went to pick him up, he played the first two recordings on his system and took off. I exited the building and tried the usual tricks to get him to show up, but he didn't. I don't know if he would have eventually returned because I reverted to a save before turning him over and then did not turn him over.
 * Sometimes ED-E will leave Primm the moment he appears there, for me he headed towards Goodsprings, because he's part of your quest you can simply use your map to locate him, and then fast travel ahead of where he's going, when he runs into you the quest is complete and you can have him follow you again.
 * When Ignacio called me on Ed-e the subtitles froze during the 3rd or 4th line then the speech continued but no in that of Ignacio's voice but a deeper (Mexican?) accent. It was the strangest (slightly horrifying) thing. It happened in Reppcon Headquarters on the first floor after I picked up Jenny Millets security card.
 * Post Patch 1.01 in hardcore mode ED-E can be killed but not removed from the part. You see it explode but don't get a message and don't lose the perk. No known workaround besides reloading.
 * Post Patch 1.01 ED-E will sometimes pick fights with random NPCs. It's unclear if this is a game bug or just a bug in ED-E.
 * When Lorenzo called me via ED-E, I was frozen in one spot without any HUD and could not do anything but look around. Tested in 3 different locations, yeilding the same result.
 * Sometimes when ED-E is given to the Followers, his laser appears to stop working, and trying to change his weapons on the companion wheel shows no name. (ps3)
 * (xbox360) After triggering 3rd dialogue sequence with ED-E, the game will crash. HUD will disappear, player will be unable to move or interact with any world objects.
 * (ps3 and possibly others) After having ED-E get upgraded by Senior Knight Lorenzo, you will lose all the items in ED-E's inventory, ED-E may refuse to attack enemies and follow you.

Behind the scenes

 * The name of the quest is a reference to the 1956 song: "Eddie My Love" by The Teen Queens, which reached #14 on the Billboard Hot 100 chart in March of that year.
