Dexter

She turned heads on True Blood - okay, her head was turned on True Blood - and now Mariana Klaveno hopes to do the same on Dexter.

The actress has booked a recurring role on the Showtime hit, as Deadline reports she'll portray Carissa Morris, a professor at Florida University. She'll likely be a colleague of Edward James Olmos' murderous character, also a professor on season six.

Klaveno, a friend of the site, will appear on multiple season six episodes. She also stopped by Hawaii Five-O last year.
