Damon and Stefan will die at the end
After watching last episode I realized that Damon is beyond redemption. Elena is gone for good cause we know Nina won't come back no matter what they say. Stefan sold his soul and breaking up with Caroline again!
I think they will die and their souls will go to a better place because their friends will help them to break the deal and cut a new one.
It looks like Caroline is free again and since Klaus is going to have a new love interest and we are told it will make some fans upset and some happy. I have a feeling they are freeing Caroline for him. Not too happy about it but someone will be happy and someone will be dead. Besides I think I heard Paul and Ian saying that they want their characters to die at the end.
