Quote aerinha: The only reason Stefan has to be miffed is that Elena jumped in bed with Damon 24 hours after the break up. Yes she was single, yes the feelings had been brewing for awhile, but it was sort of heartless.
But then if .caroline had kept her yap shut, Stefan wouldn't have found out how soon it happened.
It is a triangle so eventually Stefan does have to work his way back in. I think the show has five or six seasons in the contract so this has to go on for another year and a half or two and a half.
The sucky thing though is that Stefan found out about things out of order.
He learned about the sire bond, THEN found out that they slept together even though us readers know Damon slept with her before he knew anything about it. So when you combine that fact with Damon being caught in a lie over being with Elena when they went to help Jeremy, it potentially creates the false impression that Damon took advantage of the sire bond. And that more than anything could potentially set him off.
But we'll see... hopefully he'll give Damon the benefit of the doubt here.
I think Stefan will know it came before the sire bond announcement because, he was the one to tell Damon, then spent all that day and night with Damon so no Delena sex could happen then. It either had to happen before that (meaning in their 24 hour break up time or else she cheated) or the night Damon didn't send her away, but then Caroline wouldn't have known because she spent all day at the winter dance and/or with Stefan.
Plus there was that devastated look on Stefan's face and he gave the "checkmate" on the chess board. If he thought Damon used Elena I think he would have been raging out the door to kill him rather than being so upset.
I think he'll doubt will be, if Elena's feelings are real, how long did she feel that way about Damon while she was laying next to Stefan at night.
