"I'll see what I've got to work with once we get outside." Eventually, she does find the way to the lobby and out of the building, and picks a spot far from any flammable things like trees to dump her load of mushrooms.

"We're gonna need some firewood." Since she can't access her Manipulator's inventory, they'll have to gather some. Though she doesn't want to actually hurt the trees to get it if she doesn't have to; hopefully they can find some dropped dead branches somewhere. The dead stuff is drier and easier to burn anyway.
