I can't understand this - someone explain? [there be spoiler in here]
I just watched it and enjoyed the movie quite a bit. But there's one thing that I can't make sense of, and that is why Roy - who is obviously highly intelligent - got caught in the first place. When Martin tells Roy that "you're really good" at the end he responds be expressing regret that he got caught: "Yeah, I got caught though, didn't I?". Clearly, it was a mistake. But where did it go wrong? Is that ever hinted at in the film?
And it seems a little odd to me that this brilliant person would get himself caught being completely covered in blood and having stepped in blood and trampled all over the apartment as well.
Did I miss something?
