On Serena's last shoulder-padded day in Paris, Lily phones to let her know that they've discovered a possible Chuck Bass corpse in the river. So now she has to ID her brother's body, head back to NYC, and keep Blair from finding out/melting down before she's back in the States. For a girl who literally does nothing all day, as like her entire calling, that is quite a task list.
Though Chuck's dead for now, Henry is fine! Hot as hell and living it up with that Veela girl in some kind of French bohemian fantasy world of wine and bicycles and baguettes and what have you.
