This exchange is so awesome with its execution. Entirely on its own it could give Royce his own prequel:
Edwin: "You came back for us. You really are a good man..." [prepares to stab Royce].
Royce: "No, I'm not." (intercepts the attack and jams the scalpel into Edwin's throat) "But I'm fast."
- It's the whisper, that little smirk, that inflection in Royce's voice that says, "You forgot who was Alpha Badass, bitch!" that shows why Adrien Brody was perfect for this role.
