Quote from Audrey in the episode An Old Mustang
Mandy: I think it's sweet they have something to do together. Audrey: Your dad always hoped to rebuild the Mustang with Connor. Mandy: Seriously? Dad and Connor? Audrey: Go look in the attic. There's footballs, baseballs, fishing poles, bows and arrows. Your father tried everything. He did not give up on your brother. Mandy: So what happened? Audrey: He gave up.
