Stewart had some apprehensions about shooting that scene. She didn't want the scenario of two teens, one being a vampire who happens to be many years older than his facade of 17, deciding to marry one another to look silly or unbelievable.
"Well, to decide you're gonna marry someone at 18 is a pretty hefty decision," she told MTV News from the red carpet of the premiere of her new movie, "The Yellow Handkerchief." "And I didn't want to look stupid. I didn't want it to look like kids getting married. You know what I mean?"
Stewart said she had to find an emotional space that allowed her to make a teenage engagement seem plausible. "I wanted to be, like, 'Oh! Wow! I would say yes too!' You know what I mean? So I don't know how you do that. You try to do it for real, and it felt good. I hope it turned out alright."
