Anyone who has read the series, please answer this question!

Well the show is sort of different to the books. Not to different but they have changed a few things. In the books she does not freak out. She is shocked and doesn't believe at first but then she accepts him.
Anyway I think she screams because Stefan is probably thinking of how she might react when she finds out. That scene where she is making out with him then she screama are probably Stefan thoughts. But then I'm only guessing. x.

Elana and Damon doesnt go out in the book or the show and i think Elana screamed because when Elana finds out Stefan is a vampire in the book she freaks out and so im thinking she finds out Stefan is a vampire and thats why she screamed.I hope i answre ur quistion.

yes she will be with him next season!

hmm i dont get cha the show?? or the book.. peoples im geting confuse writte questions of the show!! if yeah what epesoide!!

Well it may seem that she will fall for her lover but stefan seems to be over with elena because he is caught sleeping with rebecca klaus sister so hopefully see falls for damon
