Colin Sullivan is a slippery fellow. He grew up in the Southie area of Boston, both parents were both dead and he was raised by his grandmother. ColinÂ soon met Frank Costello the Irish Mob Boss, who became his father figure. When Colin grew up he joined the police, Costello asked him to inform for him.
Frank Costello: But Colin - I hope I don't have to remind you that if you don't find that cheese-eating rat bastard in your department, most likely it won't be me who suffers for it. Colin Sullivan: Now why would you have to remind me of that? Would I be any good at what I do if I didn't fucking already know that? Frank, you gotta trust me. Alright, just trust me Frank. Hey, it fucking involves lying and I'm pretty fucking good at that. Right? Frank Costello: Maybe because it's always been so easy for me to get cunt, that I never understood jacking off in a theater.
Colin Sullivan: Frank? What the fuck is wrong with you? Frank Costello: [laughing] See anything you like, Colin? Colin Sullivan: I almost fucking shot you! Frank Costello: You're not indulging in self-abuse, are you? I hope you're not turning into one of them sob sisters who wants to get caught. You're not cracking up, are you? Colin Sullivan: I don't crack up. Frank Costello: Picking a place like this, where any cop can see you. Jesus. Colin Sullivan: If it was such a fucking bad idea, why'd you show up? Frank Costello: [turning to face Sullivan] I own the place. Colin Sullivan: Look, I gotta tell you... Frank Costello: You're getting re-assigned. I know. Colin Sullivan: How the fuck do you know that? Frank Costello: Where'd they put you? Colin Sullivan: Hey Frank, I gotta find myself. Frank Costello: You're telling me, sonny boy. Colin Sullivan: I gotta find the guy you got in the department. Frank Costello: With everybody looking up their own ass, and you looking for yourself, I'd put my money on nobody finds nothing.
