Kay rolled her eyes at John downplaying his fever, "it can be" she countered, "gotta say though, it's a change to hear a bloke downplaying his fever and not exaggerating everything" she teased with a smirk. Sure it was a smart ass comment but one she couldn't resist making as in her experience it was true. Chas nodded his agreement to Serena's theory as that's what he got from the whole situation as well. "that's what I think and as worrying as this theory if mine is, I think they were sent to take John out because they either a) know John is close with Kay and this you, which means taking John out they get rid of their main obstacle, whilst also making it an attempt to break down Kay or b) taking out John means taking out the one person who has the power to track said magic energy and get you both back. Either option don't sit well with me as both means they know more than we could imagine and brings up the question 'how much more do they know?'." he replied.
