Fia clung to him as he held her, also hoping she wouldn't ever have to hear that sound again. She never wanted to witness her parents die, but here she was experiencing that loss, even if it was temporary. At his question she shook her head, "I don't. I've never understood why though, none of us have..." She replied to him, about to say more when she heard and saw through the door her mum screaming and coming back to them. She barely got a chance to pull away from jOhn when he quite literally threw himself at Kay. So she remained at the doorway, arms folded. 

Kay clung to John instantly, "I'm okay...so is Fee" she told him, closing her eyes tightly so she could try and stop herself from possibly crying. "I thought I was gone too" she then added, "it was my own stupid fault I put you through that. I'm sorry" she apologised, remembering the moment she went through the glass roof because she didn't focus and felt herself going dark as she incinerated one of Midnite's men. It made her let go of John just enough to look down at her hands. She hadn't killed anyone in her entire life, injured them, sure, but never killed them. 

Chas listened to him explain what happened and he didn't like it in the slightest. "come on, we better get you both inside where it's safe" he told Drake, helping him inside. "Josh is with Serena in the main room and Kay is resurrecting in the cell downstairs. By the sounds of it, something is happening" he told him.
