I think Stealla threw the picture down when she decided to jump, because it really did surprise me that she wanted Ben's half and not Phil's, so it must of been that she wanted it as some kind of trophy. So I think she threw it as she wanted to take it with her. My theory of why Phil's hands were as they were is that he always does that when he feels guilty about something - he felt guilty about Dennis before he had that Macbeth type dream, and if Stella jumped, would have felt guilty about that.
