Chapter Four Part Two Up! (Jan 29th) · 11:58pm Jan 29th, 2021
Because I have apparently abandoned any sense of maintaining my proper posting schedule anymore. 
Well, that, and I am on day two of a four day weekend from my work for medical reasons, so... why not.
...and I might want to attract some new readers who might not otherwise see the story because they don't look at the website on the days it usually posts. 
Regarding this part, there's not much else to say I didn't already say in the author's notes. I did come up with a few secrets for those who weren't featured, but nothing all that exciting or interesting, since I never intended for them to matter. They also would have been refined, and a couple of them tweaked. But for those curious:
Apple Bloom's involved her pirating movies, as part of her schtick with the Canterlot Movie Club.
Sweetie's involved her accidentally poisoning her father with buttercups, as an allusion to Undertale.
Twilight's was based on further humiliating her about her sex life.
Wallflower's was a joke about her being into exhibitionism. (And probably would've been something different if I'd decided to actually give her secret to anyone that mattered.)
Timber's was going to imply he embezzled funds from Camp Everfree.
Pinkie's was going to be about drug use in some fashion, not necessarily the way she used drugs in Chapter Three, but more about her using them occasionally at her parties.
Like I said, many of these would've been altered and enhanced had they mattered. I came up with the base secret ideas back when I decided on the initial cast, before I knew who would live and die. And before I decided that someone's secret would involve them being the traitor.
I've finished the first part of Chapter Six. It's the longest individual part to date, a whopping fifteen thousand words. I'm working on the first part of the trial now, and I believe I will be able to move at a faster pace now that I've moved past the initial hump. I'm equal parts thrilled and terrified as I work on it. It's quite the experience.
That still leaves Scootaloo and Rainbow Dash. Very suspicious...
To recap:
Sunset had Trixie's.
Sweetie had Sunset's
Twilight had Adagio's.
Scootaloo had Flash's.
Flash had Rarity's.
Rarity had Fluttershy's.
Rainbow had Applejack's.
Applejack had Tiara's.
Trixie had Apple Bloom's.
The secrets left in circulation are: Sweetie's, Twilight's, Pinkie's, Rainbow's, and Scootaloo's.
We don't know whose secret Apple Bloom, Pinkie, Fluttershy, Adagio, and Tiara had. Unless it was Apple Bloom, one of them knew/knows who the traitor is and didn't come forward when the secrets rule was lifted.
Of course Chapter 6 is the longest.
It always is, at least in the trial
Don't copy that floppy, AB.
