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 are earned through a number of ways, 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', if you kill the spy: +1, if you disarm the monorail bomb: +1.
 * Killing the Legion leader: +2.
 * During the side quest Booted, rescuing the hostaged Powder Gangers: +2
 * When first arriving in Nipton, killing Vulpes Inculta: +1
 * During the side quest Back in Your Own Backyard, if you kill the hostages: +1. If you save them: +2.
 * During the side quest Eye for an Eye, eradicate the Legion for: +2.

Also, during Wild Card: A Change in Management, if you just go in and 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.

Quick walkthrough
Once you have done enough quests with Boone to gain his loyalty, he is willing to talk to you about Bitter Springs. You can suggest going there, but at first he will say no. Later on, however, he will talk to you again, and request that you go there. Once you get there, 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 there 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. 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 (1st answer for 1st Recon survival armor, 2nd for 1st Recon assault armor).
