Your uneasy relationship with Robert Pattinson jump-starts the narrative.
Yeah, he was lovely and I was so impressed with what he did in the film. I was touched by the vulnerability of his character. He’s almost like a little kid or a vulnerable animal that needs to be looked after. You can’t help but empathize with him. And then it meant that I knew the power that I, as Eric, could exert over him—even in the few first moments when I speak to him. I just let him know that he means nothing to me. I guess I’m trying to deny what he does mean to me and I end up having to take him with me to find his brother. I just have to let him know that he means nothing to me, personally. It’s a way of him asking if we can connect and me more or less responding “absolutely no way.”
