@motokare, since you're clearly translating from the volume, can you confirm if “Ch. 17.5” is included in Volume 3, as the LatAm Spanish scans have it, or not, as I have it? Also, what is the official numbering if it is included?
If my current marking ends up being wrong, the reason for that error is that it's not on the TOC as this bonus chapter was. Speaking of, for intended reading order, you should number this Ch 6.5 within MD and then put “Case 2.5” in the title. (It's placed at the end of the volume.)
(Also I realize that becase you have Volume 1 you don't necessarily have Volume 3 but I figured it was a small enough leap to be worth asking.)
