[ Ari, the only person who fully understands Atsumu here.

It's a reasonable reassurance on Amos' part after the fuss that Atsumu just made. His biggest worry isn't for himself (for once), though he is still genuinely not enthusiastic about putting himself in harms way this way. The whole plan feels half-baked at best, and risky as hell, but it seems like it's going to be carried out whether or not he joins in.

So if he suffers the consequences for whatever the Zenites do, and he'd rather not see his fellow members end up dead or at the least dissipated for their actions, then he only has one choice here.

At least, there's only one choice that he keeps circling back to. ]

Just worry about takin' the guy out, alright? I've got some tricks up my sleeve that oughta keep me outta the worst of it if things get hairy.
