Re: Team Sif/Team Foster?
I don't know why he has to be in love with a human. I'm just saying that seems to be the story they're telling for the movie, by all indications. You don't have a female lead played by a huge name like Portman find your male lead, nurse him to health, and teach him about humanity just to stick him back with his ex, played by a relative unknown. That doesn't exactly make for a satisfying conclusion except to us geeks who are totally in love with Sif, and Marvel knows they already have our money.
