Yep. I paid attention to this during this week's episode. When they were at the restaraunt, the waitress never acknowledged him, nor was there any drink or silverware on his side of the table. He touched the girl's head near the end of the episode, but Dexter's dad also touched Dexter's son's head in the hospital.

I say the professor is dead, or a second personality to our new serial killer.
