Kay was taken aback by the sudden familial touch of affection by Serena but didn't do anything about it. She just wasn't expecting it, but got over it the moment Serena left the room and then the mill house with the two men. Her main focus was on John right now so she turned her attention to the blanket on top of the bed and placed it over John as he shivered. "I know you do, I hate seeing you like this as well" she told him. 

Exiting the mill house, Chas looked at Serena, "so where do we go? You know?" he asked her.
