We will get two outcomes here:
1) the characters do whatever they do due to psychological trauma, depression, pressure, situation etc playing the big part on their mental health
2) or the infamous characters do whatever they do due to evil magic forcing them to do so
First is an interesting outcome which could force the characters to develop by fightning their problems head on, in similiar way what May and Bern had to do, act and survive through in their stories, and the other is simple we did whatever we did cause a third party magic forced us to act like that and it's of course not our fault at all, so lets move on and forget about it.
Seeing how Crest dealt with Moby like a true Maytag would it's rather the 2nd easy one happening, but maybe i still cling to some hope that what happens started with the characters having these ugly feelings inside and the magic just made it stronger than it being complete mind control evil magic to do bad things. Also since we don't see what other two, meaning Vennice and Glyph, are doing with the knives, seeing Moby was defeated by Crest eyes and voice already, that should be more interesting to see as a result, especially since Glyph has someone to stop him in that moment, while Vennice was looking like someone who will cut her veins alone in the room to just bleed out without anyone noticing.
Seeing the result of Crest vs Moby I'm just disappointed, since I hoped Crest wouldn't get out of it so easy like usual, but maybe that's the boon of being the only male MC in this comic.
