The finale of this episode was so funny in the irony, great come back, Virginia's Son is like Captain 'Murica before the drugs, and her Daughter really have a fetish for older guys lol, in which I think they should explorer but I doubt a little because of her age.
This episode was better than the pilot, the pilot sucks.
Not so good mistery. I figure who did with 11 minutes of play time. The professor obviously was the one since he had a 40% approval, it was obvious he was cheating in a challenging context.
