Below is a promo for next Monday's Gossip Girl episode, "There Might Be Blood."
Serena invites Aaron to a charity gala honoring Lily and Bart, but discovers a secret that Aaron has been keeping that makes her question their relationship.
Blair agrees to babysit the 15-year-old daughter of a big-time Yale donor, hoping it will boost her chances of admission, but it proves harder than expected.
Jenny and new pal Agnes plan a guerilla fashion show of sorts, with high stakes - it will either launch Jenny's style stardom or ruin her chances completely.
It also appears as if Little J's strange relationship with Nate - and Rufus' reaction to that and other things - takes a dramatic turn (possibly involving cops).
