I Forgot to Remember to Forget

I Forgot to Remember to Forget is a companion side quest in Fallout: New Vegas.

Synopsis
It is obvious that Boone has a traumatic past, but he refuses to acknowledge it, and therefore cannot move on from it.

Walkthrough

 * 1) Accumulate five "history points" by traveling with Boone.
 * 2) Kill Vulpes Inculta for one point and Caesar for two points.
 * 3) Kill the captured centurion Silus at Camp McCarran for one point.
 * 4) During the quest I Put a Spell on You, confronting and killing the spy in the act yields one point and disarming the monorail bomb yields one more.
 * 5) During the quest Booted, rescuing the hostage Powder Gangers at the Legion raid camp yields two points.
 * 6) During the quest Back in Your Own Backyard, you can mercy kill or rescue crucified NCR troops in Nelson. Mercy killing the NCR troops yields one point, while saving them yields two (2) history points.
 * 7) Eradicating the Legion soldiers (including Aurelius of Phoenix) from Cottonwood Cove yields two points.
 * 8) Speak to Manny Vargas in Novac or Bitter-Root in Camp McCarran about their tours of duty, especially the Bitter Springs Massacre.
 * 9) Talk to Boone about what happened at Bitter Springs.
 * 10) Accompany Boone to Coyote Tail Ridge near Bitter Springs.
 * 11) Eliminate the three waves of Legion soldiers raiding Bitter Springs.
 * 12) Speak to Boone and either suggest he make amends over the Bitter Springs Massacre or follow a path of vengeance.

Behind the scenes
The title of the quest is a cultural reference to the song "I Forgot to Remember to Forget", written by Stan Kesler and Charlie Feathers, sung by Elvis Presley in 1955.

Bugs

 * 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.
 * 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.
 * Both points you get during 'I Put A Spell On You' may not count; whichever you do first (save the monorail or kill the spy) will count as one history point, but upon completing the other task the other history point will not register.
 * 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.
 * If you have killed all the NCR in Bitter Springs, this quest will fail immediately after the fade on top of Coyote Tail Ridge.
 * 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.
