I have completed Dead Money. When I entered the BoS I had Boone and Ed-e as companions. They were not permitted to go to Sierra Madre. When I returned to get Ed-e back, which he was returned to Primm, I am not able to. Ed-e becomes hostile to everyone!!! I had no problem with getting Boone back from Novac. Help!!! Has anyone else had this issue? If so, is there a way to get Ed-e back.

I'm almost ready to go back to the save before starting Dead Money and end companionship mode before entering. Has anyone had issue with retrieving companions (Ed-e) after Dead Money if they are not your companion before starting? Please Help!!!

Yeah, you can. Look around the DLC hints forum. I put a solution there. ED-E is in the thread title.
In brief, you have to catch him in VATs before he turns hostile, then talk to him really fast. It's a pain but it works. Full instructions are in the other thread.
