There's a visible relaxation in his shoulders, like John had been squaring up for a blow. It doesn't come, which is more surprising than not, but he's going to inquire. For now, the conversation is drawn away from the subject of them and steered to more immediate troubles. Generally, he would put a pin in it, try and broach the subject again later, but right now, he's not sure he ever wants to revisit this.

"Besides the obvious? No one really knows yet. It's a dead city, undedground, in a cave. Any former residents and info on them is gone." John's done some intel gathering, even tried the library (which, he thinks, might be the second time he's ever been in one). When that had turned nothing up, he had turned to his message on the network, hoping someone else might know something. Dead ends, all of them. They were all in the dark together. "We're on our own down here, scrounging and surviving. Kind of like MSF's first days, but less weapons and better shelters."
