The evidence used for Save Values equaling timelines doesn't add up for me.

For one thing, the Flowey situation could very well easily just be resetting time, and not creating a new timeline.

And as for the fun value, that just seems like a game mechanic rather than a new timeline being created by The Player's actions.
