Well said, aussiechic! I'm all for a new female character as a love interest for Peter, but I don't want her (or anyone else for that matter) to steal screentime from Astrid. I think she deserves some focus after three seasons of very little character development. I wish they had given some hints of attraction between her and Peter, but I think they love each other as friends and nothing more
A new female character would be fun, but I hope it's not an Amy Jessup kind of character. They should shake it up a little by bringing in someone, who isn't working for the FBI or the government. Oh, and they shouldn't make her a villain. That is, of course, if they are willing to get a new female in the show
I've read that theory of Peter as an Observer quite often lately. I'm not sure I like it, because Josh would have to shave his head and eyebrows
but if they bring Josh back as an observer, a new female as a love interest wouldn't be necessary, would it?
