Billy isn't really expecting thanks, but he knows Robin will probably try to give one at some point. With the bottle open, he hands it over so she can take the tablet she needs.

"I'm gonna stay to keep watch over you while you sleep, okay? Give you some peace of mind while you rest up."

This time he pulls a spare chair over to rest in this time, rather than taking up space on the bedside table. She'd need the space for the medicine, mug, and water cup after all. "So you'll have me and your dog to keep an eye on you."
