The remark about Chas was one Kay could easily agree with. The poor guy had been with John for years, seen all kinds of shit, tries his best to live a normal family life all at the same time but also makes sure things are good here at John's too. He was a complete saint in Kay's eyes. Then came the others and seeing John in the state he was got her instantly scared and worried for him. 

She let Serena take control of the situation, knowing she knew what to do a lot better than she herself did. Chas nodded at Serena's commands and removed John's shirt for her. Kay stepped up so John could properly see her, "shh, you're gonna be okay....it's gonna be okay" she told him. Fia stepped back and ran her hands through her hair, angry that she wasn't fast enough in stopping the hellhound getting to her dad. "If I just had been quicker to react..." She mumbled under her breath.
