"What, are you fucking stupid?" Hank's been trying to handle this professionally and directly, looking for answers to serious questions. Mello's dismissal of just looking into it is abrasive.

"Yes, I wanna look into it. Your word means actually jack shit to me. All you've done is get up here, ask for help, and repeat that, 'yeah, things are pretty shitty. Here is what I know. Next to goddamn nothin'.' Only a special sort of asshole says, 'trust me because I said so.' I wouldn't be any better than the blind ass idiots that just follow the fluff articles. Consider that the next time you start raggin' on someone for their ego problem."

Maybe it's a bit of an ego problem for Hank, too, and to a certain extent, he can tolerate being talked down to. But blindly buying into this shit? Nah. He's not going to.

"Considering you're also fuckin' telling me that you invited everyone here despite knowing it could put their lives at risk-" especially if they're cops taking a huge risk in even showing up "-you're gonna fuckin' talk to us like that? Nick's been great but you other guys can eat shit. You wanna make their deaths worth something? You tell me who the fuck they were. Or not. I'll look into those missing people with or without your fuckin' help."

Hank has hard limits and not much pride. But having half a not to just follow someone else's bravado is definitely one thing he's got pride in.
