Well, that was fully awesome. Serena wakes up roofied in Queens and calls 911, and before you can blink Lily has committed Serena to the Ostroff Center against her will. Jenny rushes home to confess, alerting Juliet -- who actually OD'd Serena, secretly -- and Vanessa to the situation. Vanessa sells Jenny out before she can do anything, causing the usual rift between Humphreys; joke's on her when Jenny comes to Blair, confesses the whole situation, and sets everybody on Vanessa's heels.
She runs to her horrible parents, where they make vegan shoes of her and we never hear from her again; Jenny runs off to Hudson for a very real banishment that won't end anytime soon.
