Underworld: Evolution ending explained (spoilers)

[camila]

Alexander Corvinus (Derek Jacobi) is the father of the original Lycan/Vampire twins William (Brian Steele) and Markus (Tony Curran). Markus mortally wounds his father and takes the key to William's underground cell, where he encounters the hybrid Michael (Scott Speedman) and apparently kills him, too. Selene (Kate Beckinsale) is brought to Alexander, who gives her his blood before dying, telling her that after drinking his blood, she will not die with the rest of the vampires when she kills Markus (meaning that Alexander was a werewolf/Lycan himself, making Selene another hybrid). The now powered-up Selene fights Markus while Michael returns from the dead to fight William. Eventually, Michael tears off William's upper jaw and head and Selene forces a wounded Markus into the propeller of a helicopter . Selene closes the movie with a narration that even though the source vampire and Lycan have been killed, and with them their descendants, there is still evil in the world, and she hopes she will be able to deal with it.

The first of the vampires, Marcus, awakens and sets out to free his brother, William, first of the lycans. Selene realizes the reason for her familys death was because her father was the one who built Williams prison, with the keys being the locket Michael got from Lucian and the other inside Viktor. Marcus gets the keys and drinks Selenes blood to access her memories of the prison. Selene and Michael finds Alexander Corvinus, the father of Marcus and William, who then does nothing as his vampire son impales him with a wing. He later redeems himself by letting Selene drink his blood, so she would be strong enough to defeat Marcus. In the end, Michael kills the freed William, and Selene kills Marcus. The sun rises and Selene realizes she no longers burns under sunlight since she drank Alexanders blood and is now a hybrid.
