The trio heads to the Diaz apartment for Olive Garden, and Carmen comes home to find the peaceful dinner. She tells Robby he's always welcome at their house, pleased that Johnny finally got them to friendly terms.

That night, Miguel calls her crying, admitting that his father isn't the man he thought he was. He's ready to come home. Any time I put him in a band tee, Billy and I talk about this a lot when I bring in the shirts,” Helmer said. “He says, ‘Johnny Lawrence would never go see that band.
