Klaus

After Elena removed the dagger, Elijah wakes, and Elena makes another deal with him. In a flashback to 1492 England, Katherine meets Elijah and Klaus for the first time. Elijah and Klaus were raised as brothers, but Klaus was the result of their mother's affair with a man from a werewolf bloodline. Elijah's father hunted down the man and had him and his family killed, beginning the schism between werewolves and vampires. As a vampire/werewolf hybrid, Klaus can only be killed by a witch. The sun and moon curse was fake – the real curse is that Klaus's werewolf side had been forced into dormancy by witches. Jenna finally finds out about the vampires from Stefan and Klaus/Alaric. Elsewhere, Katherine is being held captive by Klaus. Damon finds her and gives her a vial of vervain to protect her from further compulsion. At the end of the episode, Maddox and Greta (Luka's sister) perform a ritual to release Klaus's spirit from Alaric's body and put it back into his own.
