When Annie is diagnosed with Hypertrophic Cardiomyopathy, like Caleb, everyone is anxiously awaiting to see if she will survive or say hello from the other side.

They met on the subway. It wasn't that special to her. But then they meet at school, same classes. Maybe they would be friends? But they just can't know her past. She won't let them.

if annie didn't kill herself, then who did?
