The Trasks move to Salinas, and as soon as they're all nice and settled, Lee goes to Adam to have a talk. It's time for him to leave and open that bookstore.
Adam thinks that the boys will be crushed, but they are more concerned with a basketball game and hardly pause to say good-bye.
So off Lee goes, not promising to write.

After the game Cal and Aron talk about Lee leaving. Aron bets Cal ten cents that Lee will come back.
Six days later Aron wins the bet. Lee comes in and just starts fixing up Adam's failures in the kitchen like it's no big deal.
