12. Louis and Blair’s Royal Wedding (Gossip Girl)
With three men vying for Blair’s (Leighton Meester) heart, it was unclear whether or not any wedding would occur. However, she decided she belonged with Louis (Hugo Becker), even after professing her love for Chuck (Ed Westwick). Naturally, an ill-timed Gossip Girl blast dropped that bomb on everyone in the church — seriously, we’re supposed to believe cell phones would be allowed inside their royal wedding? — and Blair had to explain herself to her groom. Louis decided to go forward with the ceremony, but at their reception she learned she wouldn’t be getting a fairy-tale ending. Realizing she’d made a huge mistake, she called Dan (Penn Badgley) to help her make her escape. And if that weren’t enough of a shock, Georgina (Michelle Trachtenberg) was outed as a stand-in Gossip Girl. Whoa.
