After keeping Nate away from his own surprise "Assassins" birthday party all day and making Serena sweat, Jenny decides to try to be seductive and "kill" Nate. But Jenny, either you need a haircut or new extensions. I'm not sure what's going on there, but either way your hair looks terrrrrrrible. Fix it please. Also, that scarf makes you look like an elephant.
Meanwhile, Derota gets engaged. Awww, how sweet! (I like that ring) Anyone else notice that the ring is on the right hand? They must have flipped the picture. GossipGirlFail.
