Big Blue (Chapter One)
She "appears" in Ethan's imagination while they share a phone call, where they chat about school plays. She was in the Spring pageant while Ethan is in the Thanksgiving play. They both agree that their father can get angry about things, for reasons they don't really understand.
Though they haven't seen each other in person for years, the two talk by phone when they can (when their dad can afford it), and likely write to one another at times as well. She is nice to him and remains curious about his life is going, while she is doing a little better herself.
