Regan recognizes the boy from the Home, though she doesn't know his name. She doesn't know almost anyone's names, there, and part of her thinks maybe she should change that.

When he waves, she waves, too, with a small smile. He gets a bit closer, so Regan pulls her notebook out of her backpack, which she still carries pretty much everywhere, and writes something down.

I can't hear. My name is Regan.

She turns it towards him when he's close enough to actually see it, hoping to nip any awkward, one-sided conversations in the bud.
