So Momo did the scars to herself, I was expecting they would make a bigger deal about it with a confrontation but instead of throwing magical attacks the main battle was done with the cards.
Suika is quite obviously inside Momo right now, just without her core maybe, she was playing the flashback too and that's why she now knows about Shami, I knew something like this would happen and that's why I wanted Momo to tell her the story with words instead of having Shami dive into her dreams again.
The good thing that came out of this is the whole deal with Gushion, those altered memories that Momo didn't remember are important even if Suika wants to kill Shami now. We also see Shion being born in a single panel.
The immediate reaction Momo had to hearing her friends were killed was cut off with a black panel, while fitting, I was looking forward to that too. Instead we just jumped to the confrontation. I guess there are things even Momo doesn't want Shami to see.
The gay part of the chapter, Momo being the most troubled about the cards being from sealing Joshua and Shami just not giving a damn was hilarious. Useless lesbians both of them.
