The Vampire Diaries EP Julie Plec has a spoilery preview into Damon and Elena's sire-bond. Plec teases the issue will force them to 'dig deep' and flesh out a solution, while Stefan finds his own strength.
Does Elena really love Damon? Or is it all that blasted sire stuff?
Damon and Elena are both going to be asking themselves these questions. Damon, used to rejection, is probably going to question it even more than Elena, who has a very strong opinion about how she feels.
When does Elena find out?
Is there any real hope for Damon and Elena as a legit couple?
The sire bond issue will force them each to dig deep into their feelings towards each other as they try to define and defend them. This could either make them stronger than ever or tear them apart.
How does Stefan react to Elena being sired to Damon?
For Stefan, the shock turns to hope that this helps explain why he and Elena grew so far apart. But we'll also see a lot more of Stefan finding his own strength and redefining what he wants for himself.
