Zam: You're Jango Fett aren't you. I've heard of you, you know. I'm Zam Wesell.
Jango: You must be new to the business.
Zam: Why? Because you haven't heard of me?
Jango: Because you're reckless. You could learn a thing or two about being subtle.
Zam: You call that subtle? You just brought down a Republic prison.
Jango: My plan didn't include you. Or the chaos you started back there. You cost me my ship.
Zam: My plan didn't include you trying to hijack my prisoner. Anyway, you should thank me. This babe (the ship) is a big improvement over that relic. I've never seen anything like this. What is she (the ship) anyway.
Jango: She's a Firespray pursuit special.
