Hmm. They threw her into a hole in the floor. Inside this hole is a room large enough to keep a dragon. Based on the expected size/height the room (one floor) is supposed to be along with her falling err angle? position? From page 3, it is more likely she landed on her head than on her butt . If she somehow went 360 and landed on her butt (like page 4 right most panel) then the fall would have been longer (2-4 floors depending on the strength of the push) and more fatal, (possibly breaking her spine)
Yep. The MC is dead.
