Kay held her hands up as if to say 'No complaints from me, I won't..' knowing that even if she wanted to heal Serena, she knew realistically she couldn't. Like Serena said, she was still far too drained to heal another being. She hated that she couldn't just make things better for Serena but she had overdone it by mistake with John so she had to stop at some point for a while. SHe smiled softly as Trish came over and sat next to her whilst also explaining what the spirit looked like. 

She kind of got what the kid meant by looking like something from Harry Potter, but it seemed John knew it so much better than she did as it seemed to ring a bell with him. She looked up when John made a beeline for the study before calling down to Chas. Chas heard the request and instantly got up going to where John kept the blessed oil and then scanned as quickly as he could the shelves for anything from Asia, grabbing what he found as he found it, then headed back toward Serena, gesturing for Josh to move out of the way. "Trust me, you're gonna wanna stay back for this and let John do what he does best" he explained. 

Josh nodded reluctantly and headed closer to where his sister and Kay were on the other couch, perching on the arm rest beside his sister.
