I know this is completely moot-point since there's no way to go back & change it, but if there was some way to magically insert Eden into the opening scene - at Channing's party, - what do you think she might've said? She probably would've looked much the same as she did in the flashbacks of her & Robert on the island of Las Serenas. I can imagine her making some joke about Channing always flirting with her friends, or about Channing being a tough act to follow. Somehow I also envision that Mason's resentment would've been more apparent if Eden had been present as well. As it was, Mason made some light-hearted joke about how his girlfriends were too often Channing's rejects, so we only get a vague sense of sibling-rivalry.
