Kay felt him relax and sighed with relief. She kept one hand on his but sat up a bit more, grabbing her sketchbook and pencil, pulling up her knees so she could rest her book against her legs and continued to sketch with her free hand. She couldn't figure it out but she just couldn't leave John unattended, even though she was usually far from ever giving a shit about anyone in recent years. She was barely even aware of the other two up above them as she just let herself get wrapped up in what she was doodling, letting her pencil tell her what to do next rather than truly thinking hard on what she wanted to do. Chas nodded, glad that such things weren't a problem for Serena, unlike with Kay. He noticed how she put a marker in the book so she could easily find the relevant information once again, thinking that's exactly what John would have done. As she walked by his eyes rows rose in curiosity, sensing the aura from her and he wasn't even remotely as in tune with all things magical like John was. He was just the cabby in his eyes with only a small amount of magical knowledge. So if he could sense it then it had to be incredibly strong. "right, stay safe when you're out there" he told he. "you got a phone? Let me sticky number in it so if you run into trouble you can speed dial me and I'll be there" he told her. It was only fair that they all exchanged numbers as he just knew it'd come in handy at some point.
