Elijah, for all his mythic stoicism, softens when he looks at Klaus. “This is my responsibility, Niklaus. Yours is your daughter. Let me do this for you.” In a flash, he is vividly reminded of years long gone, as he pinned his younger brother’s arm to allow their parents to visit the worst kind of abuse onto him. He had been complicit, and he’s spent a thousand years trying to make up for that one betrayal. He raises his hands to cup Klaus’ face, trying to get him to look him in the eye. “Hope is dying, and this can save her. If this plan succeeds, that means she will live, and she will need you.” Hayley was already gone, and his niece deserved at least one parent in her life. In his mind’s eye, he sees not the man Klaus has become, but the child that Elijah had failed to protect, and that solidifies his decision in his mind. “It’s okay, Niklaus. I am okay with this.”
