I think its 50/50
Part of me thinks Sasaki knows what he's doing and he has everything set up.
Another part of me thinks Uta is about to screw with all of them
It's definitely a mistake because he doesn't know who Uta is and trusting a ghoul that might or might not (might in our case) have an agenda of his own is a wrong move.
Totally agree bro, although having them get into their ghoul side and understand it a bit more would be interesting for sure.
Now, what do you think Shuu will die next? Donyou think he will try to look for Hinami let's say.
