In the book, Beautiful Stranger, they are still at the premiere party. Anna is dancing with her boyfriend Ben as Sam dances with Eduardo. I predict that  Anna will feel more comfortable with Ben and move in together. I also feel like her & Sam’s relationship as best friends might crumble to the ground. Maybe Anna will be jealous of Sam.. or Sam will be jealous of Anna & Ben’s relationship. Who knows ? Although this is very uncertain at this time, but maybe as the book goes on, my prediction will be right.. or at least close to right.
