Hey, I'm trying to think of the best way to explain the Retcon mechanics, and I think they best way to explain it is "The user of the Retcon is able to manipulate their own existence." Because it doesn't work like Space or Time, in that space is limited to that plane of space and time seems to have to follow a very specific rule-set, not to mention that the powers seem limited to their session. What do you think?

Thing bigger. Wider. The Retcon Mechanics don’t take into account Space or Time loops because it’s a Meta power. It reaches for the Plot of the story, it allows the manipulation of the story on a Meta level- Similarly how John can suspend LOWAS in literally nothing but the background of the Website.
