These finales left our jaws on the floor and our hearts in our throats.
The Vampire Diaries Season 3
After a pretty sedate episode, the game changed in the last five minutes of The Vampire Diaries Season 3 finale when Elena and Matt's car drove off a bridge. Our screens cut to black on Elena's corpse surging back to life because, whoops, she'd ingested vampire blood earlier that evening. Enter vampire Elena!
The Walking Dead Season 2
The rise of the Ricktatorship plus that little reveal that everyone was infected with the zombie disease was a huge way to end the second season of The Walking Dead. Talk about a game changer! But the real award for this cliffhanger goes to the entrance of Michonne, the mysterious katana wiedling, zombie owning savior!
Castle Season 6
We were so close! So close to the dream wedding! Kate was even in her freaking wedding dress, but then a horrifying car crash nearly ruined it all! Who could ever forget the heartbroken look on Kate's face as she found Castle's car engulfed in flames?
Grey's Anatomy Season 1
Merder hearts around the world broke into a million tiny pieces when Addison Shepherd showed up in Seattle to reveal that McDreamy was McMarried. McAwkward...
Game of Thrones Season 1
The image of a butt naked Daenerys flanked by three baby dragons was possibly the best ending to the best first season in TV history. High praise, but well deserved. It completely changed the mythology of the show, plus it spawned about a thousand Mother of Dragons memes.
Supernatural Season 3
After spending an entire year (okay, six months - damn that writer's strike!) trying to save Dean from his hellish fate, the Winchester brothers finally failed. Our last moments of the season were spent with Dean in hell, wondering how on earth he would ever make it out of there!
