It's getting a tiny bit predictable at points, but it's still very exciting. I would've flown through this, had I not needed some sleep as well.
There's a bit of filler, but the story picks up again quite quickly.

Spoiler

Kasane has to deceive Nina's mother and father, but the mother suspects something. Kasane makes it so that the father thinks the mother suffers from the Capgras Delusion, which is pretty horrible, but pretty neat that she pulls it off.

Still a 4* series for me!
