Shima hums a humoring sound, not bothering to correct Rin since he's sure it'll become clear enough he doesn't mean that, though it's probably true he could be taken advantage of.

"What's the rush? I had a job ta do before, so I couldn't just come out 'n tell ya everything. But well..." Shima steps back a little, bringing his hand up across his eyes and dragging his thumb hard across them--for a gut-wrenching moment it looks like he's torn right through his face somehow, but only darkness pours forth from the tear, wrapping around him and solidifying into a frankly kinda flashy outfit.

"It's all gonna end soon, so there's not much point in hiding what's going on. But maybe ya don't want ta find out, huh? Ya gonna let your brother carry the whole burden up to the end?"

He's not saying this out of compassion for Yukio so much as he knows that's going to be a sore spot for Rin.
