Gossip Girl's final season is almost upon us (commence heaving sobs), and there are certain loose ends that need to be tied up. And no –– we're not just referring to Serena's (Blake Lively) crazy mane of hair.

Some of our favorite characters left Gossip Girl for bigger and better things, and we're desperate for them to reappear while they still have the chance! Of course we're talking about Eric van der Woodsen (Connor Paolo), Vanessa Abrams (Jessica Szohr), Carter Baizen (Sebastian Stan), and the lovely Jenny "Raccoon Eyes" Humphrey (Taylor Momsen). All four of these troublemakers left the mean streets of the Upper East Side without bothering to say goodbye, and it's just like: What gives, people?

We haven't heard from Jenny or Eric since they were shipped off to London to "go to school" (we're so worried), Vanessa hasn't been seen since she stole Dan's (Penn Badgley) Great American Novel and scampered off to Barcelona, and we can only assume that Carter is currently gambling his life away in some shady underground bar. Sigh, come back to us, friends.

Ideally, we'd love to see Jenny, Eric, Vanessa and Carter stop by Gossip Girl's before the show airs its last episode ever this winter. But if you had to choose one character for a surprise guest appearance, who would it be?!
