Theron is home and life goes back to what passes for normal for all of us. Grandma and Grandpa got to know him a little better.
Theron: Can I take my shirt off?
Theron: Because I'm going to turn into the Hulk and I don't want to ruin my shirt.
Grandma told him he could come back - after having him sign a contract for expected behavior. Theron's signed these kind of contracts before, he'll sign anything you put in front of him. Unfortunately I don't think he considers them legally binding. You might have to sue him.
