By now Ange is at least somewhat aware enough of what's going on that it's not surprising to find herself in this place, even if she may not know all the specific details behind this event. And seeing Nageki quickly establishes that this is his.. memory, or weird guilt dream world, or whatever it's supposed to be.

The human being pushed in momentarily distracts her though. This place seems to be some sort of lab, and she guesses she could imagine reasons for Nageki - or anyone - to be here. But.. why would they just randomly push a human into his room? That human doesn't even look like a doctor or anything, and--

Well, then they fall down. And are pretty obviously dying, despite there being no visible cause of death as far as she can see. Is that person just having a heart attack? But then why does Nageki look so miserable?

She's none the wiser when the memory repeats, but what she does know is that she's not just going to stand there and watch this a few times. Instead she approaches Nageki.

"Hey!" Her voice is raised a bit compared to usually, but it's mostly since there's some actual emotion in it. Yes, that is indeed a rare hint of concern. She swallows down the urge to ask what's even going on here, and instead asks-- "Are you okay?"
