I Forgot to Remember to Forget

 is a quest in Fallout: New Vegas.

Activating the quest
Note: You must talk to Manny Vargas in Novac first about his tour of duty in NCR and Bitter Springs before related speech dialogs are available with Boone.

The player requires 5 "history" points with Boone. These must be earned with Boone in your party, listed below: Note (confirmed on PC): With Boone in you company, it is possible to accumulate multiple history points with Boone by repeatedly resurrecting (using console command "resurrect") and killing Curtis. This approach will prove useful in unlocking Boone's personal quest "I Forgot to Remember to Forget" and no fame between factions will be lost or gained by doing this.
 * Camp McCarran
 * When torturing the captured Legion POW Silus at Camp McCarran, if he dies during the torture: +1.
 * During the mission 'I Put a Spell on You' at Camp McCarran
 * If you confront and kill the spy in act (Capt. Ronald Curtis): +1.
 * If you disarm the monorail bomb: +1.

Note (confirmed on PC): If there are problems with activating the quest, Aurelius can be resurrected via console. After each kill there are more dialogue options when talking to Boone till the quest finally starts.
 * The Fort
 * Killing Caesar at The Fort: +2.
 * Legion Raid Camp
 * During the side quest Booted at Legion Raid Camp, rescuing the hostage Powder Gangers: +2
 * Nelson
 * During the side quest Back in Your Own Backyard in Nelson
 * If you kill the hostages: +1.
 * If you save them: +2.
 * Camp Searchlight / Cottonwood Cove
 * During the side quest Eye for an Eye (begun at Camp Searchlight; executed at Cottonwood Cove), eradicate the Legion for: +2.
 * After killing Aurelius of Phoenix in Cottonwood Cove.
 * The Tops (or The Fort if Benny escapes)
 * Confronting Benny at the beginning of Ring-a-Ding-Ding.
 * After the mission 'Ring-a-Ding-Ding' if you kill 'Benny'.
 * Killing Vulpes Inculta: +1

Also, during Wild Card: Change in Management, if you kill all the legionaries including Caesar, it should bring up the dialogue option after Boone mentions Caesar's death.

Note: You must always advance in dialogue with Boone when "history" is earned.

Note: If you have enough history points but the extra dialogue does not trigger, then go to Cottonwood Cove and kill the Legion, this should trigger the dialogue and quest for you.

''Note: If you have done all the above and the dialogue still hasn't triggered, go back to Novac and make sure to talk to Manny Vargas (The other Sniper). He should have a "new" dialogue about Bitter Springs. Exhaust those dialogue options with Manny and it should open up new conversations with Boone.

Detailed Walkthrough
In Novac, you must first talk to Manny Vargas about the Bitter Springs Massacre. This is the only way to actually get Boone to talk about Bitter Springs. Without Manny talking about it, the dialogue to activate the quest will not appear until after you have spoken to him. Once the player has gained Boone's loyalty, he will speak with you about Bitter Springs. The player can suggest going there, but he will initially refuse. Later, however, he will talk to you again, and request that you go there.

NOTE: It is strongly advised you complete the Bitter Springs quests prior to going there with Boone as the Legion raid on Bitter Springs often results in either Lieutenant Markland or Captain Gilles getting killed, making all three quests unobtainable. The quests are: No, Not Much, Bitter Springs Infirmary Blues and Climb Ev'ry Mountain. Also, make sure your companions are not carrying explosive weapons. When they use grenades or missile launchers, they may kill a Great Khan or NCR member in error, ending in infamy and possible hostility from the attacked party.

Once you get to Bitter Springs, he asks you to go to Coyote Tail Ridge, where he was stationed, and tells you exactly what happened during the massacre there. He then asks you if you don't mind staying overnight. If you say yes, the screen will fade out and fade back in, with Boone telling you that a Legion raiding party is on the way. The Legion raiding party is not so easy to defeat, you may want to be a high level or have good weapons, having the Alien blaster could help very much, although with Boone it is much more simple.

The attacking Legion forces come in three waves. The first two waves come toward Bitter Springs up the sloping hill. The third wave comes through a small gap in the side (where the graveyard is located). The battle is much easier if you mine these locations before going with Boone to Coyote Ridge, but if the refugees flee the Legion, they go in all directions (including through the graveyard pass) and will be hurt and/or killed by your mines, turning the survivors hostile. So it is preferable to not mine these regions.

You must then defeat the Legionaries to save Bitter Springs. Once they are all dead, Boone will talk to you again, and at the end of the conversation his armor is upgraded depending on your last answer. ''Note: Although both armors are only cosmetically different, this choice actually influences Boone's part of game ending.
 * 1st answer yields 1st Recon survival armor
 * 2nd answer yields 1st Recon assault armor

NOTE: In non-hardcore mode, it is possible (but difficult) to deal with the Legion raiding parties without gaining Legion Infamy, using two companions (one of which is Boone) and an NCR Ranger called using an NCR Emergency Radio. First travel to Bitter Spring so that you discover its location. Then fast travel to another location within the NCR-controlled area, such as Camp McCarran. Fast travel back to Bitter Springs, and the Ranger will stay in position at the entrance to the camp unless you interact with him/her. Then move around the camp to the smaller entrance to the west, set both companions to aggressive, and tell your robot pal (ED-E or Rex) to wait by the graves in the canyon. Then you can got to Coyote Tail Ridge with Boone to get the conversation and wait overnight. The idea is that the ranger and robot will hold up the raiding party for long enough for you to get there with Boone, and you stay hidden and don't fire any shots.

When the raid starts, start running towards Bitter Springs main entrance, and use a Stealth Boy, crouching and moving when you get close enough to see the gunplay, where the first wave should be being driven back by the Ranger. It is still possible to be detected if you are moving quickly within the raiding party's area of perception, so crouch and move when you get close - don't crouch-run unless you have the Silent Running perk.

Ranger and Boone should then make fairly short work of the second wave. You can now interact with the Ranger, who will then follow you and Boone as you run through the camp to the western entrance where, hopefully, your robot should have slowed up the third wave long enough for them all to end the raid. Not sure whether it's a glitch, but your robot may keep losing and then regaining consciousness, which will keep the third wave well away from the camp as they try to deal with it. As long as you're not seen, and don't fire a shot, the quest will end with no loss of status.

Bugs
To be able to continue the quest, open the console and enter the command This will skip the part of the quest that's glitched, and allow you to begin the "Go with Boone to Coyote Tail Ridge" section of the quest.
 * After beginning this quest and traveling to Bitter Springs, Boone will sometimes not initiate the conversation necessary to continue the quest and will have only his default dialogue when spoken to.
 * Dialogue with Boone will not start when you reach coyote’s tail ridge making the quest incompletable (this can be fixed by reloading an earlier game)
 * Sometimes, if Boone approaches you saying that he's ready to go to Bitter Springs, but you don't immediately accept, he may become stationary and will not move again until you talk to him and tell him that you want to go to Bitter Springs.
 * If you have played the entire game with another companion and cannot earn any additional history points, on the PC, go to the console and typing to start this quest.
 * Version: After the start of the Legion raid, the game freezes.
 * If Boone is still looking for enemies even after you have defeated all of the Legion, Boone might say "Let's get through this first," when he was supposed to say the scripted line.
 * Talking to Boone after killing Vulpes Inculta, may cause game to crash.
 * Sometimes when Boone Stays for the night at Coyote Tail Ridge, the game will crash after fading out.
