Kay had a feeling the reason why John was holding back was because of Fia, so she let him hang back as she went on ahead with Chas. Fia looked down at her hand then up again at John, looking him in the eye as he told her to just focus on getting Kay, Serena and Bane out if it goes south. It was a plea she didn't like, she didn't want it to come to a point where she'd have to leave her father behind. "It won't come to that, I'm not leaving any of you behind. Without you getting out safe with mum, there'll be no me after all" she told him back, giving him a slight smirk that could mirror his own. But she wasn't amused, despite her outer appearance, she was dreading losing either or both her parents in this time. 

Chas stayed with Kay as he looked behind him seeing jOhn and Fia having a chat, as well as Serena and Drake and he could only imagine what was being discussed with them. Noticing Fia's smirk, he felt like he was looking at John and it was endearing as well as slightly disconcerting due to technically Fia not even existing in this time yet. Yet seeing Fia standing there beside her father gave him hope that she would be a beacon for John not to screw things up or give up on anything.
