Chas paused at the top of the stairs when he heard Drake ask him what they should do. Stepping back toward the room they were in, he leaned on the door frame, "find anything to do. But mostly you take it easy. I don't want anyone overworking themselves and doing themselves more injury. There's gotta be a room in here somewhere that needs books stacking back into shelves or something" he explained. Tapping the doorframe as he pushed himself off, he headed to the stairs yet again and walked down them. He saw Josh talking with Serena but didn't interrupt them, instead he headed to the kitchen to clean up there. 

Josh have a small genuine smile when Serena agreed to take some time out to rest and relax. "if that's what you want" he replied to her, not wanting to overstep his mark with her in the slightest.
