Maybe if Zack wasn't a psycho, he wouldn't be to bad. But of course.. he loves to annoy you. Even if you are his boss.

He does the dirty work while you do the research. You find the target, get info on their whereabouts and give it to Zack. He never asks why you want these people dead. Usually not caring enough. He simply likes the thrill of the kill.

But one mission you forgot to warn him about the bodyguard this target had, and he got hurt. It's not life threatening but it hurts like hell. Now he's being a brat and taking up the whole couch because he said his wound hurt to bad for him to do anything.

He requested soup, and like the good person you were, you got some, bringing it over to him. His eyes lit up and he licked his lips.
