This is a good way for Brea Grant to wash the stink of Heroes off her: the actress will be appearing often on season six of Dexter.

Not much is known about the actress' character, but she wrote on her official website today: “I’ll be recurring on Dexter this season! No spoilers, but i’m pretty sure you’ll be seeing me in a white lab coat.”

Hmmm... a white lab coat. That hint doesn't offer us many clues about Grant's role, as no other recent addition to the Showtime hit - Billy Brown, Edward James Olmos, Mos Def - has been cast as a scientist or doctor.

Guess we'll need to tune in this September to find out more.
