Kay went with Trish to the kitchen, looking through the cupboards to find cleaning supplies which she assumed was down to Chas and not John. She pulled out cloths, cleaning sprays and other stuff. She handed Trish some sponges and a surface spray bottle, "use that to spray the worktops and use the sponge to wipe it clean" she explained. 

Chas paused his walking and looked at Serena and Josh, "yeah, he's sleeping in his room so we're all clubbing together to do a bit of tidy up and stuff. You and Josh just relax. We got this covered" he replied with a smile. He could see how tired Serena was after saving John's life and didn't want her exerting herself anymore than she already had. He knew she would be in safe hands with Josh and that he wouldn't let her over do it. 

(Yeah, she had a total knee replacement so been a bit crazy as I take over on everyday stuff and stuff whilst she recovers)
