Kay made the facial expression of 'ohhhhhh' when he explained what he actually meant before shooting him a sheepish smile. "No I didn't know I was doing that bit, I thought I was just being nice and giving you a hug" she explained, before she too heard the front door open and frowned at Chas and Serena interrupting their weird nice moment together. She was about to jump off his lap when he picked her up making her hold onto him by draping one arm round his neck to the back of his shoulders, and the other holding onto his shoulder from the front. She saw the state of Serena and frowned in worry, wondering what on Earth she did to make herself that drained of energy. 

As Serena began to fall as she tried to protest being carried, Chas grabbed her with the aid of her shadows before getting in front of her, squatting down and lifting her onto his back piggy back style. "Serena, no protesting, you can barely stay upright" he told her just as he saw John and Kay appear and he couldn't help but raise an eyebrow at the way they appeared. He did not expect to see John carrying the woman and wondered what they arrived to. He figured it was nothing riskay as they were both very much fully dressed but it was still curious noen the less. "Uh, yeah and no. She's cold to the touch and weak as she used way too much energy. She needs rest quickly" he explained. "I'll explain properly when I got her to bed" he added, stepping forward whilst making sure he had a firm hold on Serena.
