Before the folks by the broken skyway even really start to strategize, those in the heat of it follow through with their plans. The iron gets in at the Mother's soul, and she begins thrashing and falls over in a way that very clearly communicates pain... and maybe dying.

Papyrus doesn't loiter on the edge and hope for the best, but moves in closer. With those limbs flailing about, people might get crushed underneath. He can at least watch and try to tug them out of harm's way with blue magic, now that he's not trying to keep himself in the air or her farther away.

...Besides. It feels like... somebody should watch. There's nobody here she hasn't hurt, but he doesn't hate her so much as her choices, and in a little way he wishes she'd taken his idea to make herself less awful, and let them go. But who knows how long it took the Ringmaster, before she started befriending people. It might have taken the Mother thousands and thousands of years of trying before she even got that far.

There's just something horrible about the idea of dying friendless and surrounded by enemies. Even though she brought them all here, and hurt them all, and is the reason they're enemies at all.

Even though she said she didn't mind the way she was, and didn't want to be frail.... She's dying anyway, isn't she.
