My top three are Boone, Veronica, and Lily. Who is the best companion in Fallout New Vegas? The easiest way to gain these points is killing Legion with Boone as a companion.
In order to get him to open up to you about what happened at Bitter Springs and begin this quest, you need to gain 5 ‘trust points’ with Boone. Trigger: Boone probably has the toughest Companion Quest to trigger.
