The Lord - Marcus and Catherine on Gossip Girl...OMG!

Can you believe The Lord/Marcus and his Step Mom Catherine are hooking up on Gossip Girl? Marcus is suppose to be dating Blair and Catherine is suppose to be having an affair with Nate Archibald.   I think Marcus is out of High School, but Blair and Nate are still in High School.  That's pretty illegal for Nate to be messing around with Catherine.  But dang, does this show have some awesome drama!  I love the show and I wish it was on more than once a week.
