Fortunately for Rey, William doesn't reply. Instead, he behaves as any armor should: silent, flexible, reassuringly protective as she makes her way through the cold, wide space of the bay. Unmolested by were/wolves, wonderfully.

He can hear her. But she doesn't need to know that.

William is channeling a low but steady rate of psychic healing into her body as well. Of course, it's doubtful Rey will notice as long as they remain unharmed, but as the sounds of violence grow... well-- trouble seems more likely by the moment.
