"We did block it within the rehearsal room, and we visited sets and, did all that kind of thing . . . It was also, then, discussion really. It was me and Jude, really, that we were really trying to figure out what that relationship was, because we didn't want it to simply be: she is good, he is bad. We wanted it to be much more ambiguous than that. So we spent a long time discussing what their past relationship had been and where the love was, and when she is completely blinded and when he is completely blinded."
