Dexter cutie does double duty guest starring on Gossip Girl

It’s rare when my guilty pleasure shows and my not-so-guilty pleasure shows intersect, so I greeted this news with a little shiver:

Desmond Harrington, who we all know as Quinn, Deb Morgan’s shady partner on this season’s Dexter, has been cast as uncle to bad boy Chuck Bass on the CW’s Gossip Girl.

On Dexter, Quinn’s questionable past and the internal affairs investigation it spawned have left us wondering just how much of a bad boy he is (bad enough, we wonder, to go around killing off Freebo’s associates and keeping little strips of their skin as souvenirs?).

On GG, he’ll not have nearly such a dark character arc, though we’re guessing he’ll hook up with one of his much younger co-stars. Those of you who know the show, weigh in  below on who you think he’ll bed.
