When last season left off, all the relationships were in disarray. Blair (Leighton Meester) and Dan (Penn Badgley) were no more, and Blair took off to Europe to find Chuck (Ed Westwick) before he got into any more trouble. Meanwhile, after Serena (Blake Lively) messed things up with Dan and Blair, once again, she took off on her own, drugs in tow. Will her friends be able to find her? Find out tonight on the final season premiere at 9 p.m. ET on The CW.
