Phixius

Question: There's a scene in which, right after they've bought their house, Henry appears in their living room, naked and shot. I just don't see how this can happen because this would constitute a travel within a travel. That is, he travels to where he gets shot. Shot, he then travels to the newly-bought house; then finally travels back to the Christmas party from whence he came originally, where he finally dies. But the movie never establishes this sort of "Inception"-like travel. He always travels to one time, then comes back. Is this something that the book clarifies, or is it a mistake from the movie?

Answer: Since no rules are ever firmly established in the film, there's no reason he couldn't have done this. So it's not a movie mistake. The book addresses the nature of his travel a little more in-depth, and even there this would not have been impossible.
