Law takes charge! He doesn't even ask, he just shambles Stone and those lovely batteries out of the building entirely, to Stone's vast annoyance (he immediately shifts big once out there, the better to protect the batteries and the better to bellow at Rosi and Law once they join him later). Then Law cuts through the door to the control room so he and Rosinante can see what's inside. He's ready to evacuate them both if need be, if there's something dangerous on the other side of that door, or if the locals and their dust catch up to them.
