Changing Charlie was one of those skills that Sarah had to pick up on quickly, and some of it was mental remembrance from when she was younger. She felt like a mother, and in some ways she was, though that moniker was not one she'd put on herself. It was good that he had had a friend; Sarah had figured the girl was deaf, and Sarah was hardly a master at sign language. Well, that's what the girl's father was for, or Charlie if it came to that, though Sarah doubted she'd be having many conversations with her. A brief moment of relief set in as Charlie dozed off. Sarah gently patted her brother's back, holding him as he slept; it was the least she could do. Outside, Emily nodded to her father at his question. She signed in response, her eyes locked onto her father's face. "Yes, I think her name is Sarah, he signed it earlier. She doesn't seem nice, but Charlie likes her, so how bad can she be, really?"
