I completed part one where I brought him the Platinum Chip and watched his Securitrons get upgraded, etc. Now he wants me to go back to the Fort but my only chat options are "The Legion will kill me on sight", "That's insane", etc and there's nothing that will start the part 2 quest then I have to say goodbye. The Legion hates me so I'm not sure what to do. Also, I never killed Benny after getting the Chip the first time at the Fort. What do I do?
