I Forgot to Remember to Forget

 is a quest in Fallout: New Vegas.

Activating the quest
The player requires 5 "history" points with Boone. These must be earned with Boone in your party, listed below:
 * When torturing the captured 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 kill the spy: +1
 * If you disarm the monorail bomb: +1.
 * Killing Caesar at The Fort: +2.
 * During the side quest Booted at Legion Raid Camp, rescuing the hostage Powder Gangers: +2
 * When first arriving in Nipton, killing Vulpes Inculta: +1
 * During the side quest Back in Your Own Backyard in Nelson
 * If you kill the hostages: +1.
 * If you save them: +2.
 * During the side quest Eye for an Eye at Cottonwood Cove, eradicate the Legion for: +2.
 * After killing Aurelius of Phoenix in Cottonwood Cove.

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 talk to Manny Vargas first about his tour of duty in NCR and Bitter Springs before related speech dialogs are avaliable with Boone.

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.

''Note: If you've killed Aurelius of Phoenix or Vulpes Inculta, you can resurrect them and kill them again to get more History points.

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 Mannys' talking of it, the dialogue to activate the quest will not appear until you have talked 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.

Once you get to Bitter Springs, he asks you to go to the point he was stationed, where he 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

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 armour is upgraded depending on your last answer. ''Note: The armors are only cosmetically different, their stats are identical.
 * 1st answer yields 1st Recon survival armor
 * 2nd answer yields 1st Recon assault armor

Bugs

 * Boone will not talk to you once you have activated the quest when you arrive at Bitter Springs.

Behind the Scenes
This quest title is a reference to the song 'I Forgot to Remember to Forget', performed by Elvis Presley and written by Stan Kesler and Charlie Feathers. Released in late August 1955, it became one of Elvis' top singles for two weeks during the following year.
