Some of the things in the Hobbit films are not entirely from the book. The love triangle was made up by Peter Jackson. Gandalf encountering Sauron, and Saruman's appearance are taken from the appendixes, not the actual story of the Hobbit itself. The Hobbit mentions that Gandalf leave the dwarves and Bilbo (however it does not say what he does during this time). The appendixes fill in the gaps.
Peter Jackson added the appendixes in to the films.
