So at the absolute minimum, I managed to keep that promise: a double-chapter month. (This one's in the 9000 to 9800 range on the word count -- I'm still trying to figure out exactly how FIMFic adds things up there.)
The world seems to be trying to fight me on updates: I'm now struggling against a cold, and lost some additional time to vehicle transmission investigation. (All now well.) But I managed to get the two chapters up. A new section for Anchor Foal should be next, and I'll fight to get to five postings for April, as best I can. I'll probably fail, and I'll definitely sneeze. Possibly a lot. But at the absolute minimum... for Triptych itself, we are on the doorstep of the party.
The middle is over. We're about to move into the beginning of the end.
Oh, and we're also about to get at least one Mandatory Update Downvote on the story. Some people just can't resist the chance to sling a little MUD...
