Status :	 Killed by Arthur Mitchell

There was plenty of time for Arthur to kill Rita. I watched the episode the second time to work it out. It took too long for Dexter to realize that Arthur got his car fixed. There was a huge gap of time and Dexter managed to get to the car before Arthur.

Dexter "becoming" like his father training Harrison doesn't seem like something that is that far fetched... I mean just read the books....
