As far as Hellboy knows, there isn't currently a central shelter. Maybe he'll find out about one later and he'll get them shuffled over there then, but for now this is it. It's pretty bare inside, but the shelving on the walls, the secure doors, and some of the scrapes on the stone floor suggest that this might've been some sort of storage room at some point. That the place is so bare, however, does present one sort of problem, and he scratches at the little goatee on his chin as he acknowledges it.

"Well, you might have to manage for a little while." Reaching into his coat, he pulls a slightly battered old-fashioned metal canteen from its spot on the back of his belt, shakes it to confirm that it has a decent amount of water in it, and hands it to Mabel. "Here. I'm going to go get some supplies. Lock the door behind me and hold down the fort until I get back."
