Chas nodded to both Serena and John's words. He partly felt annoyed that he never noticed his best friend black out but he also rationalised it by realising he was focused on Fia as well and himself. With Josh's help, Chas then checked John's reaction to the light, as well as seeing if he was bloodshot in the eyes which he didn't seem to have that he could spot. "Well I can't see any blood in the eye" he commented. "That's...something?" Josh remarked in reply. 

Fia listened and thought about what he said, "you're right" she replied turning to Kay, "do you have a scar on your ankle?" She asked her so she could try and make heads and tails of the timeline. Kay shook her head, showing her ankles were very much scar free. "no..I've never scarred in my life. Fee heals me so I don't scar" she explained. "...shit..." Fia muttered under her breath. "Then that's yet to come...possibly" Fia added.
