Sarah offered Charlie an apologetic look with her eyes, apologizing as best she could wordlessly, apologizing for not being the one to change him. She lacked in the confidence department on that, and besides, the nurses had to do something to prove that they were actually competent. Noticing he was shivering, Sarah attempted to aid the matter by gently patting the top of his smaller hand, which was currently placed in the palm of her much larger one. It wasn't a blanket, but it's the first thing she could think of under the circumstances. Even as the nurse explained about the wires, her gaze wasn't focused on the medical staff, but she nodded in understanding regardless. 

Sarah gave a soft sigh at Charlies request. Of course she had to do it, it was just that she hadn't done it in years, since being out on her own involuntarily. She asked the nursing staff to leave for a moment, this wasn't for their ears to hear. Sarah cleared her throat, still holding onto Charlie's hand. "Now it's time to say goodnight. Good night...sleep tight..." She adopted a soft sing-songy voice, slightly rougher than the past - the cigarettes and other substances did her singing voice no favors, but she kept her voice low and as comforting as she could, lightly patting Charlie's hand in the process. "Dream sweet dreams for me....dream sweet dreams for you...Good night..."

Sarah finished the lullaby with a faint smile. It was quite the nostalgic feeling.
