Alright so I'm at the part where I have to get Cass to follow me back to the energy weapons shop, but she just wont follow! I've tryd every dialog with her and she just won't budge. Any tips would be appreciated!

Also, I'm on the quest Ring-a-Ding-Ding! Where I have to confront Benny but I can't get passed that one door without having some sort of passport ( or 2,000 caps ). I don't plan on saving up 2,000 caps so how do I get a passport?

to get benny talk to king do watever he says (only he says really dont listen to a guy named with p[something like that] and the king will get you a fake passport)

why was this moved to the fallout 3 section?
