I've never watched this show before because it seems like a Mentalist ripoff with a dash of House but when I read that Jason Dohring from Veronica Mars was guest staring I made sure to tune in. He gave a chilling performance as a sociopathic serial killer who was also very charming. He needs to get a regular gig on TV asap. I know he was a series regular on Moonlight after Veronica Mars was cancelled, but that was before the whole vampire craze took over so that show didn't last long on the air. I think he would be a great addition on the Vampire Diaries.
