"Um, the relationship between Thor and Sif in this movie is quite platonic. I mean, they're good buddies, they've grown up with each other, they're warriors, they fight side by side. We haven't take it to the next level yet. I'm going to throw that in there. But yeah, she kind of thinks he's a little bit pig-headed, but she loves him nevertheless, you know, she's like that's my buddy, I'll do what I can for him."
