So I need a rebreather. I guess only Jack can give me one. I am helping him with his "lady with red hair" (Janet). I gave her the boomer outfit that Jack told me to give to her, and she asked me to talk to Alice about her wages. As soon as we're done talking, the whole caravan company (Including Janet) turns hostile and starts shooting me. If I leave and re-enter, they are not hostile for about 30 sec. Then they start shooting. Alice, in the main office, however is not hostile and will peacefully talk to me about Janet and what not. What is going on? Janet should just thank me and leave but I can't even go talk to her again b/c she's trying to kill me. What did I do wrong?

Are you wearing a faction armor?

No. Just combat armor and combat helmet, not associated with anyone.

Does the NCR not like you or something? I'm not sure.

I've read somewhere ED-E might be causing it.

Do I have ED-E from the start of the game? I mean is there anything I can do about it?
