Unwanted Feelings
Elena just heard that Stefan is now in Klaus possession and Damon has recovered from the wolf bite already. She is very frightened by the thought that Stefan might be hurt but she's still very grateful that Damon lived. She felt very confused right now as to what Katherine told her, that she can love them both.
Her heart starts to beat faster when she met Damon's eyes. Feelings that are buried deep inside her heart starts to arise. She felt like betraying Stefan just by looking at Damon and she just kissed him a moment ago. And now, she doesn't know what to do, now that Damon lived. So before he can say anything to her, she rushed out from the room to her car and went home directly. She just hopes that by tomorrow, she won't have these feelings anymore.
