He showed up in my Novac hotel room, at first i could just talk to him but now theres a companion wheel. Only problem is it doesnt work, he wont follow me or anything and the middle EXIT button on the wheel is missing. Anybody else get this?

I had him show up once when I was fighting and when I tried to talk to him I had the same thing happen. I had to clear out the last few critters in the area before he'd talk to me.

Hrm, well hes in my motel room in Novac. I seriously hope this doesnt screw up the main quest or anything.

I kill him off when I see him... there are no real negative consequences to this though (damnit). Don't remember... but don't think any negative karma either for you do-gooders
