JJ had this thing with John B's younger sister where they both liked each other, but he was always denying his own feelings knowing that it wouldn't be healthy. Every time she showed up with a boy or even Rafe Cameron, Kook, he would freak out with jealousy and possessiveness wanting to keep her all to himself.

This was one of those days after she posted a story with Rafe on the beach, which made JJ crazy with jealousy and anger for not being able to keep her with him.
