Katana and Batman in “Unfinished Business”

What about Alfred?

May not make it in time. My arm is loose. There are liquid nitrogen capsules on my belt. I can get to them, if I can chip away some of this stone.

What good will that do?

If heat hardens it, perhaps extreme cold will reverse the process.

Really? That'll work?

Could. Or maybe nothing happens. Or the reaction could cause the liquid stone to become so unstable it explodes.

I'm going to keep my fingers crossed for Alfred.
