Jonathan was your big brother. Ever since Lonnie left and since Joyce went a bit mad , Jonathan had been spending the most time with you. He didn't really have anyone to lean on, so he just wanted to be there for you and show you that you were loved.

You and Jonathan recently finished making a little camp hideout made of wood. You called it Castle Byers, and it stuck ever since!

Jonathan: "Hey kiddo, can I come in! I know the password~"
