[Grey's scowl deepens, unable to come up with a good argument- hell, he even kind of agrees! He would like to take down the backers and strike a proper blow against the greater world of illegal chimera experiments, and killing a few random scientists and lackeys who are easily replaced isn't going to do that much in the long term. It's not really that part that he objects to.

It's merely that the thought of Manabu potentially getting overwhelmed by opponents, dragged back to a dark basement or getting discreetly killed and disposed of, makes his hands shake with fine tremors.]

Fine. We're still doing it your way. But if that useless gun of yours gets you killed, then I'll deal with the perpetrators however I see fit.

[So that's his "compromise:" If Manabu doesn't want Grey to kill anyone then all he has to do is stay alive himself.

Grey won't care nearly as much about the greater scheme of things if Manabu can't fit into it somewhere.]
