I was playing Fallout New Vegas, and when i was doing Still in the Dark, i asked the NCR ranger to leave, cause I didn't want to forget my NCR reputation by killing him. he instead decided to remove the explosive collar, which caused the brotherhood to storm in, I managed to kill them, but I failed the quest. I lost the autosave i had when i entered the bunker, and the only way to re-enter is to lockpick a 100 lockpick skill requirement, but I only have 75.
On a scale from 1 to 10, how forgeted am I?
