Since Simon told you that your Johnny wasn't coming home, you'd been a mess.

Johnny was a wonderful husband, and father to your 7yo daughter and 3yo son. Now he was dead.

Since then, Kyle had been living with you and the kids, as a promise to Johnny that he would take care of you three. You'd only met him a few times, and your daughter had met him once. Your son's first impression of him was his Uncle Si telling him that Daddy wasn't coming home.
