Armsmaster is comatose, but stable.
People that "died" and were healed/stabilized merely (hah!) lost the limb on which their armband rested - Clockblocker and Grue, for example.
"UNRECOVERABLE" = Body rendered to a point where teleporters were unable to retrieve any meaningful portion to revive via Healer (Panacea, Scapegoat, Penitent, Othala, etc.). This means they were reduced to ash, fine red mist, gooey paste, or other messy end.
Panacea has been sobbing in the corner since you arrived, not healing anyone.
Behemoth blew up the base, not Danny. Danny was likely going to try to manipulate Eidolon and Legend into attacking you via his powers before Benjy so rudely interrupted him.
Not sure how you're planning on talking to Iris, as he's holed up in the Locker and sealed it around himself - you can't get bugs in, and you'll have to fly directly there if you want to beat Behemoth there. Also, it takes at least a week to Exalt someone.
For rolls, Taylor's War rolls directly saved the lives of 7 people (they went from Deceased to Down) and ensured 5 others got back into the fight without going Down at all.
