When she hugged him, she felt something between them but she didn't pay too much attention to it, not realising it could be anything worth noting. When he asked her if she knew she was doing something, she just assumed it was the hug he was talking about, and not anything else. "Do I know I'm giving you a hug? Yeah" she replied, looking at him as he pulled back a little. "Was that wrong of me to do?" she asked baffled. She truly was oblivious to what had happened during the hug and how it made him feel, not knowing that it could have remotely been something to do with the fact they were destined to be connected in some way. 

Chas grabbed ahold of her when she fell to her knees, stopping her from falling flat on her face when he opened the door. "I think you did, you're right. I think once inside and downstairs, you should get some kip and sleep a bit to try and recoop and regain your energy. I can give John and Kay all the information on what went down properly" he told her, helping her up onto her feet. "Do you think you can walk downstairs or do you want carrying?" he asked her.
