Casca and Guts in “Unfinished Business”

Casca

(criticizing Guts' reckless behavior in battle) You haven't changed in the past three years. You're satisfied as long as you get to just cross swords with the enemy. You don't care at all about the lives of the men you lead; you're just a mad dog! (Guts grabs Casca's wrist)

Guts

You're wrong! I do think about my comrades. I'm not...who I used to be."
