She appears ready to get back together, but Crosby brushes her, deciding to head to the movie first. After school at Adam's house is a mess. Gaby is not there so Max is giving Kristina a hard time. Max throws a fit. Crosby realizes this is all his fault. Everyone tries to calm Max down, but it's no use. Crosby goes over to see Gaby, telling her to come back but it turns out that Gaby really likes Crosby and it won't work because their relationship is forbidden.
Zeek and Camille baby-sit for Julia. Syndey again says that she's not eating meat. Meanwhile, Seth and Drew head back home (safe because Zeek is not there).

She continues arguing for a while about it. Drew is disappointed; Seth and Sarah are both hurt. Drew argues that Amber won't even give Seth a chance. Syndey is still being difficult with Camille's food preparations. Seth heads into Sarah's workplace (the bar) and says that he's leaving. Seth says that he got a jig somewhere in Denver and will be leaving tomorrow morning. She asks him to tell the kids. But Sarah is very disappointed, she runs after him and says that he must say goodbye to Drew in person. Sarah says she has blamed him enough, but now she's taking action. Seth will be there at 8am in the morning to say goodbye to them.
Jasmine goes to see Crosby at the houseboat. She apologizes about keeping Jabbar from him. Crosby denies that he needs an apology, admitting faults in his ways – this difference in attitude unsettles Jasmine. Jasmine sees the guilt in Crosby's face and eventually gets the truth out of him: he slept with someone. Jasmine is completely shocked. Crosby tries to apologize again but Jasmine freaks out again, saying she will never forgive him for this one. Julia thanks Zeek for watching Syndey but not for forcing her to eat the meat. Camille speaks out for Zeek saying that Julia can't let her kid feel like she has all the power. Sydney is only six.

Amber talks to Drew about what happened – she apologizes about pushing Seth away. Drew doesn't take it personally. Amber plays the song that Seth played at the concert a few weeks back. Meanwhile, Sarah sits down at a desk and soon her hand just furiously writes and writes. Adam is not happy and very upset at Crosby. Crosby coincidentally shows up right at this point. Crosby apologizes but Adam gets upset calling Crosby selfish. Crosby says he may have lost his finance and his son, so he's not very happy either. Max overhears Adam saying that he has Asperger's.
