Complete story — includes the ending
Damon manages to escape his cage while Katherine wakes up with Stefan to find her gray hair falling out. While Elena is trapped by Wes, who is continuing his research, Damon decides to ask Stefan for help in getting Elena back. Damon comes up with a plan where they will offer to exchange Aaron to save Elena; if Wes doesn't give them Elena back they will kill Aaron. Wes reveals to Elena that her father was a doctor practicing on vampires and using their blood to help other people. Katherine continues to struggle with aging and enlists Matt to help her, who then calls Nadia. Damon is shocked when he meets his old friend Enzo who is not too pleased to see him. Though Damon saves Enzo from Wes, the latter remains indignant with him, saying Damon will always be a monster. When Wes is on his way to turn Elena into a vampire ripper like Jesse, Stefan is able to save her. Later on Damon ends his relationship with Elena when she tries to overlook his gritty past with the Whitmores. Damon feels Elena should not have to make excuses for him, and sees her attempted resolve as only an indication of her changing. Nadia returns to Mystic Falls and tries to convince Katherine in becoming a traveler so she could live longer, which Katherine declines when she thinks Stefan has feelings for her. Aaron tells Wes to leave him alone as he steals a vial from the lab. Katherine realizes that she was wrong about Stefan and decides to accept the deal, but just when she does she collapses.
