They completely explained the mystery, and unless they have an unusual season of 11 episodes, there are two more episodes left. That’s quite a lot of time to spend after the mystery has been explained.
I was wondering about the same thing.
From what I can find on the database sites, it is indeed scheduled for 12 episodes. So obviously something has to happen, and something relatively momentous (or at least that will be seen as momentous by Bertia, which will in turn make it momentous for Cecil). I can’t imagine what though.
I hoped after last week’s episode, and sort of suspect really, that Heronia and Pii-chan will get some sort of happy ending. Maybe something that oddly fits in with the game canon?
Yeah - more broadly, as I think about it, this needs some sort of resolution that will satisfy Bertia as well as Cecil - something that’s close enough to game canon to lead to Bertia accepting that that’s the way it’s “supposed” to be, and that will still allow Cecil to get the ending he wants (and really the ending that Bertia wants too, though even she doesn’t yet realize that).
We’ll see, and I’m looking forward to it.
