Erik Lehnsherr: A man from the future came to me.
Raven: Don't lie to me!
Erik Lehnsherr: I never have, and I never will! He said the humans would take your blood and use it as a weapon against us, to wipe us all out!
Raven: In that case, how'd you like to try killing me now to save the future?
Erik Lehnsherr: It doesn't matter any more. They have your blood already, they took it off the pavement in Paris.
