Marian just makes a vaguely disgruntled noise at that. Who indeed. Someone who didn't care beyond apparent glee in the existence of free energy and breaking down atomic bonds, something well outside conventional understanding of the word 'life'...

This fellow definitely knows. Should she assume they're still here then? It seems reasonable, given how inhospitable the outside environment is to anyone or anything. Ask further or settle for now? Marian's not sure, and so lets an uncomfortable silence fall for a few moments while Carlisle finishes drawing.
