1. First, Violet and Finch actually meet at school in a bell tower — Finch sees Violet standing on the ledge and talks her down.

3. One of the final places is the shoe tree they visit together early in the movie.
4. In the church, Violet finds a song written by Finch that he left behind for her.
5. Finch learns that he has bipolar disorder, and Mr. Embry is the first person to discuss it with him — it's also one of the reasons he attends the support group.
6. Finch constantly talks about the "Awake" and the "Asleep," which is how he distinguishes between his manic and depressive days.
7. Finch's mom plays a huge role in his life. Instead of simply being gone, she's a working single mother.

9. Finch creates various personas for himself, such as '80s Finch, British Badass Finch, and Nerd Finch.

11. Finch calls Violet his "Jovian-Plutonian gravitational effect" because he feels better whenever she's around.
