fic talk: divergence and things unsaid

i'm in the thick of editing S11 au right now, and it's occurred to me that i've never edited on quite such a large scale before - S11 au is currently clocking in at about 97k words, and while it's technically complete, i have one major gap to fill (gap as in "i did not write the transition from A to B, and i have to write it now), and then a lot of little things to tie up and conversations for characters to have. i keep finding things that i need to embellish or add, and it's actually an incredibly enjoyable process!

my current knot of loose ends to untangle has to deal with reconciling canon events, though, and the question is: do i describe events as they transpired in canon, or do i let the reader do it themself?

( spoiler alert: this question has no one true answer )
