Forum:Fawkes Won't Move

I have gotten to the part where you walk out of Raven Rock and you see Fawkes pwning some Enclave soldiers so i talk to him so i can get him as a follower, it let's me get him as a follower but he just stands there. When i fast travel he's still just standing by Raven Rock, please help. P.S. I got Broken Steel and now he just stands at the doctor place at the Cidatel(not sure if i spelled it correctly).
