SPOILER About The Sire Bond !!!!

Guys it's been confirmed by Julie Plec and e!Online that Elena is sired to Damon, & they've had it planned since early on in season 3. But it's also been confirmed that despite the sire bond, Damon and Elena are closer than they've ever been, and also that sire bonds do NOT impact emotions/love/sex.
Also, Damon doesn't know Elena is sired at this point. When Stefan says "she was sired to you, & you took advantage" he's talking about Charlotte (who was also sired to Damon), not Elena.

Traducere:

A fost confirmat de catre Julie Plec si de E!Online ca Elena ii este loiala lui Damon [ din cauza sangelui ] si ca ei [scriitorii] planuiau asta inca din sezonul 3. Dar a fost confirmat ca in afara de legatura de sange , Damon si Elena sunt mai apropiati decat au fost vreodata si ca aceste legaturi de sange NU AU NICI UN IMPACT asupra emotiilor/ iubirii/ sexului. Deci, in conculuzie Delena este ceva real :) 
De asemenea Damon nu stia ca Elena este legata de el in acel moment. Cand Stefan zicea "a fost legata de tine si tu ai profitat de asta" vorbea despre Charlotte [care a fost si ea legata de Damon si va aparea in episodul urmator]
