Okay. Um. Wait how the hell does the telepathic person know how long, is she just guessing– oh Marian had failed to properly parse the earlier bit, apparently because she can literally see it, like she has CT scan vision or something, that's wild and Marian viscerally covets it.
Also that would be so incredibly doomy if not for the fact that Samora can fix brain damage. But Samora can do that so they just need to...figure out why this guy isn't currently fixable with Samora's magic at all, and deal with that? Ugh, did Samora mention Lesser Restoration previously, Marian thinks she did but she failed to take notes on it or remember properly what it does except that it didn't necessarily sound like it would fix kidney failure or advanced COPD.
Relaying to Dr Chadra! "She thinks he's been down somewhere between two and ten minutes? But the arrest was unwitnessed, they only got to him later for some reason. They, uh, I think they can guess his initial symptoms because there were other people affected – uh, vomiting, confusion, loss of consciousness. And an - ongoing...life...drain?" Marian isn't going to attempt to turn that into correct medical terminology because she doesn't know what it means but she feels so stupid saying it like that. "There's a spell called Lesser Restoration that Samora has, that helped, but at an earlier stage with the other patients. There's some kind of central nervous system dysfunction from vascular damage causing edema and rising intracranial pressure? She thinks that triggered a respiratory arrest."
Pause for breath. "She, I mean the robe lady not Samora, can normally - see problems directly? Like some kind of magic scan vision, I think, maybe? But it's not working, either because of his condition or, I don't know, maybe it doesn't work on Earth or something."
