Makoto does check, skimming the app. There's no new names that he recognizes. Much as he'd hoped for the comforting presence of Takeru or Alain - hell, he'd even take Onari at this point - there's none. So it takes him a few long moments before he glances up from the app to see Chikusa.

... Who looks upset. As he heads into the hallway, Makoto flicks through the app responses, looking for Chikusa's name. And he finds it, and reads both it and the person he responded to. ... And then he gets it.

He doesn't know who this person is, but he understands the sentiment. Someone for whom he'd take their place in hell... he has several of those. Carefully, he keeps flicking his gaze towards where Chikusa disappeared, concerned both from a teammate level and... the memories of being Gen still haven't gone away. So when Chikusa reappears, Makoto goes over to him, grabbing the mug Chikusa had been using and filling it with water. He presses it into the other's hands gently, and reaches out to turn him away from the people. His voice is low when he speaks.

"... Is this someone I should be concerned for you to be around or not?"
