So what’re your thoughts on this interpretation of Mage of Time: they Know all the other timelines, like share memories with all the other versions of them (which also checks the whole “suffer from their aspect” box that comes with the mage). They probably tend to have a hard time sorting out what happened in their timeline vs what happened in others. Is this veering into heart too much or?

I’ve never personally enjoyed the thought that Mages ‘suffer from their Aspect’, that’s just kind of a bit mean when everyone suffers a lot for various reasons. It does veer a bit into Heart but not so much that it’d be implausible, however do remember- We’re explicitly told in canon that all the versions of yourself together make a sort of ‘Ultimate Self’, and bearing down the memories and feelings of all of them at once would be unbearable for a normal person. Sprites Squared are mentioned to be able to handle this.
