Left Hand, in the original film, chatises D for still trying to resist his vampiric urges, even after being given permission by the Girl of the Week to drain her.
D: "Damn you. Do you want me to cut you off?"
Left Hand: "... I'll be good."
Bloodlust has a few, usually involving Left Hand. Of particular note is the scene after D gets knocked of off Meier Link's carriage and drags his hand on the ground to steady himself. Left Hand's response?
