"No." It's an easy answer, something immediate. "One has to trust people to house them, to guard them. I can trust, perhaps, one or two people at a time. More than that and motivations and agendas become fickle, tricky things. Balancing them against my own desire not to die?"

Trickier still.

"Even staying in one place on my own would be foolish. There are things in having a known location to live in, to guard, to put down roots that are of great benefit- but I have not yet found somewhere that appealed to me enough to do so. Besides. It is a terribly romantic thing, is it not? Being a mysterious wanderer, living off of the land, culling the dead one zombie at a time."
