Chas rubbed her back as he walked with her to the other two. "I know it's hard Serena but we'll be home soon, I promise" he told her, as John replied to Kay first before checking ON Serena. He agreed that it was incredibly brave of Serena to try and hold off a demon that powerful on her own, risking her very life in the process which made him so much more glad that they came when she told them not to. He tucked his arms under her and lifted her up so she didn't have to try and walk back when she was shaking so vigorously from the attack. He started the walk back, getting the tiniest bit ahead of John and Kay, knowing it was imperitive that they got Serena back and under the safety of John's house. Kay nodded at John's question, "yeah I'm fine, a little tired but okay" she replied to him. She didn't even know how she managed to pull off what she did, wo sering if it was a case of Fee helping her in some way as she had never been able to set her hands alight before and certainly not by will. 

"I just wanna go back to your place and get Serena back." she added, leaning against him slightly as she began walking behind Chas and Serena. She had no idea if she truly had a right to lean against him like she was, but she was too tired to truly care. She had known the guy for less than 24hours and here she was leaning on him. She never would have done that to someone before. It had been some seriously crazy twenty four hours, that much was certain.
