Damon is secretly tracking down Stefan's murders and covering his slaughtering in Tennessee with Alaric. On the day of Elena's birthday, Caroline plans a party for her at Damon's house. Meanwhile, Klaus and Stefan are chasing Ray Sutton, who is a werewolf, to know the place where his pack gathers. Jeremy continues to see Anna and Vicky and he tells Matt what is happening to him. During the party, Stefan gives a bloody message to Damon to stop following him and Carolina and Tyler spend the night together. Damon is shaken with Stefan's attitude and decides to forget him.
"The Birthday" is an episode where we see the new Stefan, an evil and wicked killer. The fate of Andie Star is very cruel and Stefan looks like Damon in the beginning of "The Vampire Diaries". Caroline and Damon are very funny with exaggerated sex drive due to their new conditions. What will happen to Caroline is the question in the end of the episode. Damon lost Katherine, Rose and now Andie Star and he really liked the journalist. It is inconsistent that he sends a message to Damon to forget him, and then calling Elena. My vote is eight.
