One of Lucas' most valued traits was the one that made more than a few people hate him: his confidence. Lucas never doubted himself, his actions, his intentions. He moved through the world with purpose, never straying, and whenever he had something in mind, he would accomplish it, one way or another, no matter who he had to crush to do so.
And Edward? Edward was his masterpiece. A masterpiece he had never thought he would see again, but a masterpiece nonetheless. And to be faced with him here? Now? It was just a chance to ruin him all over again, sculpt him into what he saw fit.
Lucas laughs as Edward lunges forward, and he has enough sense to shoot a hand out, wrapping around the other's forearm to keep that hand from crushing his neck. "Monster? Monster??" There's another laugh, sharp in the dimming light above them. "You're the monster, Edward. My monster whom I brought to life. I can destroy you, but you cannot destroy the one who made you." He grins, the white of his teeth cutting through the dim light.
"You need me, Edward. Who are you if I'm gone?" Another laugh, and he arches slightly beneath the man, bringing a leg up to try and kick him away with his heel.
