Felix Gets Angry! Thank fucking god. Small step, and that's all I'll spoil, but overall I liked this update with Felix/Sophie POV better than the last pure Sophie chapter.
This is good to hear. Not that I'm expecting some amazing turn of events, but the guy has been so fucking passive since he stopped looking into Zack's background that his side of the story has been getting a bit boring to read.
Almost makes me want to pay for the update.
Almost.
Spoiler's too vague, and I'd hate to be disappointed even with my low expectations.
EDIT:
My prediction/expectations:
Felix's anger is going to be a big nothing burger. Either Sophie will find a way to guilt trip him out of it, and make him back down, or she'll use it as a justification to be a little more open about her relationship with Zack just to make Felix jealous and even more angry, knowing (believing?) that he won't do anything about it.
Second option sounds like more fun.
