The entire school is rooting for Team Matty or Team Jake while hating Lacey and her letter.
Matty and Jake reconcile after watching a French film. They decide to be honest with each other, and they each profess their love for Jenna. They ask Jenna who she's going to choose.
At home Lacey is getting calls from people who harass and bully her after they find out about the letter. Jenna tries to reassure her that she is a good mother.
Kevin tells Jenna that he constantly walked out on her and Lacey because Jenna would always fuss and cry when he held her. Lacey taught Kevin a song she made up to soothe Jenna. Jenna sings the song to Lacey to help calm her down.
The day I wrote it my mother laid into me telling me that I wasn't raising you right, and instead of tuning her out I tuned her in. And I did what I never wanted to do I attacked you the way she has always attacked me, and it wasn't right or fair it was just a family pattern that I couldn't break.
Kevin: When we were young I did and said a lot of awful things to her. Things she's forgiven but clearly hasn't forgotten. I wasn't always the best guy. Jenna: Well let's be real she hasn't always been the best either. Kevin: I know, but you've got to cut her some slack. Because what you don't know is that I wasn't always around as much as I should have been, and when I was you didn't want me to hold you. Jenna: That's not true you were the only one who could put me to sleep. Kevin: ...with your Mom's song. Singing that lullaby was the only way to get you to calm down. She wanted me to be your hero.
