That explains a lot
As it turns out, some time ago (not sure how long ago), Timmy was in a car wreck and was seriously injured. He was in a coma for a period of time and suffered major head trauma. Therefore, he really has no idea what he is doing and how inappropriate some things come across.
Rebekah is "taking one for a team" and trying to help him understand some things. This knowledge does not necessarily make the situation any easier, or any more pleasant, but it does explain some things. I do think it aids us all in dealing with things differently and seeing the situation in a different light. It's less creepy, and that right there is major.
I never really thought he was a bad guy, just that he went about things the wrong way. I just say all of this to let you know that there will be no more updates about anything associated with this situation.
