What happened in The Vampire Diaries season finale?

Answer 1

In Season 1 finale, John Gilbert trigered the Gilbert device to round up all of the tomb vampires at the founders party/parade. The device made all of the vampires fall to the ground and then they were taken into a room where they would be left to burn. Damon is caught (as well as Tyler's dad who turns out to be a wolf) but Bonnie puts the fire down while Stefan goes in and saves him. End of the parade, you see Damon and 'Elena' outside the Gilbert' residence while they are kissing.

The next scene, you see Elena coming up to the door and swearing that someone had taken her clothes and other stuff. Meanwhile, the other 'Elena who kissed Damon' is in the kitchen, tries to kill John and you realise she's Katherine. It ends when the real Elena walks into the house and hears something... Duh duh duh... (evil music...)

Season 2:

Stefan trades himself over to Klaus in return for Klaus' blood. He orders Katherine to give Damon the blood since it will heal Damon's werewolf bite, therefore letting her out of the house. Surprisingly though, she gives it to him and flees. Earlier, Jeremy was shot and while Bonnie was healing him, the witches whispered to her that there would be consequences but she doesnt listen. The last scene, Jeremy wakes up and walks downstairs. Vicki Bennet calls his name, and then Anna does. So we're guessing that the consequences are that he can now see dead people or vampires.

P.S. Klaus is making Stefan drink heaps and heaps of human blood and making him com with Klaus.

Answer 2
