Last week’s ballyhooed threesome leads to awkwardness for the parties involved. See, teens can learn valuable lessons from TV after all!

Gossip Girl – the CW 9/8c
“The Last Days of Disco Stick” – Hoping to impress the elitist theater kids at NYU, Blair sets her sights on landing a private concert with the hottest musical performer of the year, Lady Gaga. Dan and Olivia sign up to write and star in a school play, based on an idea by Blair and directed by Vanessa. With Blair out of the picture, Serena turns to Nate to help her get through a difficult situation. As a favor to Chuck, Jenny agrees to hang out with Damien (guest star Kevin Zegers), the son of an ambassador who is staying at Chuck’s hotel, but the experience proves to be a lot more intriguing than she expected.

Castle – ABC 10/9c
“Love Me Dead” — The murder of an Assistant District Attorney thrusts Castle and Beckett into the world of ex-cons and escorts. But when Castle’s desire to help a vulnerable call girl endangers the case, Beckett is forced to decide between honoring promises and putting a killer behind bars. Matters are complicated even further when Castle’s daughter shares a potentially explosive secret with Beckett instead of her father.
