I Could Make You Care

 is a quest in Fallout: New Vegas.

Initiating the Quest
This quest is triggered by Veronica's dialogue. There are ten triggered conversations throughout the Mojave Wasteland that Veronica will initiate in response ten different situations she and the Courier may encounter together. Completing three of the conversations will activate this quest.


 * Camp McCarran - Inside the terminal building. You must bring her to the center set of doors or the set of doors closest to Colonel Hsu. The third set of the doors will not trigger the conversation (bug?).
 * Camp McCarran - Discussing the OSI's current objectives with Dr. Hildern and starting the Side Quest: There Stands the Grass
 * Vault 3 - Enter Vault 3 with her
 * Casa Madrid Apartments - After talking with Anderson and starting the Side Quest: The White Wash
 * Old Mormon Fort - Talk to Julie Farkas with Veronica in tow.
 * Silver Rush Gambling Hall - Get close to the energy crates near Gloria Van Graff inside the Silver Rush
 * Nellis Air Force Base - After listening to Pete's lecture in front of the mural (don't interrupt him until he is done)
 * Nipton - Just walk around, eventually she'll make a comment
 * REPCONN Test Site - When you ask Jason Bright about what the Great Journey is, she'll talk to you afterwards.
 * Nelson or Cottonwood Cove - Again, just walk around a bit.

P.S. I had trouble triggering the quest at first as well just as the bug section said, but I just found it might has to be locations of 3 different fractions and I think one of them has to be NCR.

Detailed walkthrough
Upon returning to the bunker, Veronica will speak to the Elder in charge of the bunker, claiming that the Brotherhood must change before it dies out. The Elder rebuffs her, and Veronica vows to bring a piece of technology that will make him.

If the player has activated Helios One without using the Archimedes II weapon system, you can tell Veronica that Helios One is not a weapon, reducing your choices to the pulse gun or the farming tech.

If the player chooses the farming technology, the player can follow the There Stands the Grass at the same time.

Should the player choose the pulse gun, Veronica and the player will go and look for it at Nellis Air Force Base, where the player must evade the Boomers' artillery barrage if they have not already done so. Once inside, the player will have to sort through a filing cabinet owned by the Boomer leader. Inside the filing cabinet is a note indicating that the pulse gun has been moved to Vault 34, which must then be searched. The gun is located in the highly irradiated vault armory, among a host of other loot. Alternatively, the player can purchase the pulse gun at Silver Rush, avoiding the need to search the other locations. Once the gun has been obtained, Veronica and the player will return to the Hidden Valley bunker to meet once more with the Elder. He will still refuse to change, citing the codex. Veronica will ask the player what to do, at which point the player can suggest remaining with the Brotherhood, leaving the Brotherhood, or express apathy at Veronica's situation.

Should the player recommend staying with the Brotherhood or have her choose on her own, Veronica will agree. Upon leaving the bunker, a group of Paladins will approach you. If you have 95+ Speech, you may convince them to give Veronica another chance. Also, if you have the perk Terrifying Presence, you can make them cower in fear by threatening them and the Codex, making the possible fight far easier. Since they will not move, you can even return later with a higher Speech skill and re-initiate conversation (note that it takes some time and perhaps an area transition for them to stop "fleeing"). If you can survive the onslaught you can get some nice Brotherhood loot. Either way, this will end the quest and she will obtain the perk, Bonds of Steel which increases the defense of her armor. Your Reputation with the Brotherhood doesn't change.

If the player suggests leaving, Veronica will express a desire to join the Followers of the Apocalypse. The player and Veronica will then leave the bunker, where they will be accosted and warned by a group of Brotherhood Paladins. Once Veronica and the player travel to the Followers outpost, they will be informed that they cannot be allowed into the organization until the leader of the outpost returns the next day. After waiting a day, the player and Veronica can return to the outpost to find all of the Followers dead and a group of Brotherhood Paladins waiting in ambush. After a battle with the Paladins, Veronica expresses regret for the deaths she has caused and vows to travel only with the Courier for the remainder of the game. She also gets "Causeless Rebel" perk, which boosts her unarmed attack rate. This doesn't change your standing with the Brotherhood but Veronica won't follow you into the Bunker any more.

Bugs
Veronica will not comment no matter how long she's been with you or how many places you've gone together. Her only response to anything is What's up?. Because she won't comment on the locations you bring her to, it's impossible to start the quest. Sometimes she will comment on one item if you dismiss her and then have her join again, but after that it's glitched again and she will never make comments again.

While talking to the Elder, both Veronica and the Elder will freeze in place and will not respond to attempts at communication. Upon reloading, the Elder spouts three phrases, and Veronica is unresponsive.

After taking the Rangefinder option, if you use HELIOS One to power the grid instead, you should be able to discuss the other two options with Veronica (so says the Journal). However, when talking to her only her normal dialogue appears, rendering the mission unsolvable. Choosing to go to Vault 22 after destroying the data also renders the mission unsolvable because the terminal will be blank.

WORKAROUND - confirmed on the If you, after having this issue, take Veronica to Nellis and steal the note from the Filing Cabinet, you receive an update for the Pulse Gun portion of the quest. Complete this portion of the quest as normal and the Elder/Veronica conversation will go off without a hitch.

(This seems to be fixed in the patch, but it's still possible that she gets stuck after thanking you.)
 * Even after choosing the "She was just testing you (requires speech 95)" dialog option and getting positive response from paladins, she is unable to enter the bunker.
 * After fighting the 4 Brotherhood Paladins (doesn't matter which dialogue options are chosen) located at the entrance of the bunker, she gets blocked and will not follow you anymore.

After the Brotherhood Scribes confront you outside the bunker Veronica may become immobile. Sending her to the Lucky 38 Presidential Suite or back to 188 Trading Post will result in her disappearing. She can still trade gear though as well as back up, making her a kind of 'container' that defends itself. Traveling to Gibson's Shack and reactivating the terminal inside will fix this bug. Also, after she appears in the shack you may have to speak with her before she will be able to move again.

After the Brotherhood Paladins ambush at the Follower's Outpost Veronica may become immobile. Just like above, traveling to the Gibson's Shack, reactivating the terminal, and speaking to Veronica to select a destination will make her mobile again.

If you use the Terrifying Presence speech option during the confrontation at Follower's Outpost, you need to be sure to kill all Brotherhood Paladins at the Outpost or the quest will not be completed. If a Paladin gets away, you can fast travel to another location and back and you should find them wandering around or inside the outpost.

After completing the quest she stops following you. Fast travel and dismissing and rehiring her had no effect. Reloading to a previous save after entering Vault 34 causes a "DLC not installed" error message and forces a restart.

Randomly stops following the player which can be fixed by dismissing her and recruiting her anew.

If done after helping Paladin Hardin in the Still in the Dark quest, but before Elder McNamara is ousted, Hardin and McNamara will not talk to the player, and the Brotherhood quests will be locked. However, this does not have any affect on Veronica's quest itself. This can also cause Veronica to stop following you.

Completing HELIOS1 and choosing the ARCHIMEDESII option without activating the defense system I met with Veronica at 188 and accepted her help, she turned me down because I already had Boone, I chose to stick with Boone and left her there. After entering Freeside and obtaining the rangefinder it activated I Could Make You Care and told me to take the rangefinder to the Elder but there I have no dialogue options with McNamara. Possibly unrelated, when attempting to fire the weapon the game will CTD.
