how will katharine affect the formation of delena?
The only thing I can think of is, katherine will somehow kidnap stefan like they've runaway in love (stefan leaves a lot in the books) Which would obviously kind of force upon the idea of elana and damon. ( I mean not force in a bad way, but yeah)
or a pretty obvious thing.
Stefan cheats on elana with katherine KNOWINGLY and she catches him and then yeah...
Katherine came back for her man, Stefan. Because it always says at the beginning of each episode that he's lived in hiding and there's a risk blahblahblah. So maybe the risk was katherine finding him? I don't know. Anna said that katherine knew where damon was, and that she didn't care, but no one ever said anything about katherine knowing where stefan was? Not sure, as for theories that's about as thoughtful as I got.
Stelenaaa alllll da wayyyyyyyyyyyyyyyyyyyy <3. but i hope both brothers work it out
I think that in the end Stefan and Elena will be together. Just because first of all their love was so strong, so how they could break up or inlove with someone else, like Stefan would inlove Katherine. So, I think, that in the season 2 we will see a fight between Stefan and Damon. Because in the season 1 series we saw that Damon felt something for Elena too, even if he don't said that. Just maybe he felt that Elena is so not Katherine and Elena's good character invites him, and he felt inlove with her. I really don't think that Elena feel something like love for Damon, because from her words in last series I can say, that she really love Stefan so much, but not Damon. And in last episode we saw Katherine and Damon kiss. So, Damon thought that it's Elena. So, that is all I wanted to say from this time. I'm really sorry because of mistakes in the words, because I'm from Lithuania, so my english language is not so good. So yeah... :DDD
