[If the situation weren't as dire as it was, he might have chided Bunny for that response--more for his reasoning than the callousness; Kotetsu knows it affects him more because Fai told him the whole story, much of which his partner doesn't know. But lives should always be paramount to a Hero, regardless of personal grudges. And maybe they're not technically Heroes, here, but it's too wrapped up in Kotetsu's sense of identity for him to let it go.
[Don't chastise him, he's letting go of enough of his personal grudge to help at all. He could just ignore this.]
I'll be there as soon as I can.
[But right now he doesn't dare use his power unless he absolutely has to, so he'll be slow getting there... and probably slower finding them, since he isn't even sure of the direction to go in. But he'll try anyway.
He gives his suit a longing look; it would help if he ran into trouble and had to fight something, but there's no time. One last check of everything, and he's running out the door, headed in what he's pretty sure is the right direction to get to where Fai is.]
[ voice ]
I'm going after him. He'll die out there.
[And he's glad that despite everything, his partner knows him well enough not to try to stop him.]
Won't ask you to come with me if you don't want to.
[ voice ]
Don't be ridiculous. As if I'd leave you out there with him.
[There's the sounds of him getting ready to leave in the background.]
I won't ask you to wait for me, I'd be wasting my breath. But try to be careful, won't you?
[ voice ]
Instead, he simply says--]
Thanks. And I will.
[...probably.]
