Lol @ the scientifc approach here, Kraco

My qualm with this episode would be the lack of care for all the dead people. We see Saki, that new boy and other people walking inmidst of dead and injured people. Yet, nobody seems to really freak out.
Maybe thatīs just me, but this anime went through great efforts to portray the ultimacy of the Cantusī power, and how people felt 100% safe thanks to it. Seeing fellow citizens being killed by those "measy" queerats should be super shocking. And I mean SUPER shocking, not just "well, we had one episode showing some reaction, now weīve moved on to what follows" kind of shocking. I want to see people break down, crawling on the ground, going into fetal position and crying - at the sight of the UNTHINKABLE: Human beings beeing killed by something, and in this case, by queerats.

As for what happened in this episode, yeah, I guess Tomiko is trying to sacrifice herself. And I agree with Kraco: Just someone kill this fiend. One dead human, one dead fiend, and itīs over.
But ... what happened to Satoru? He didnīt die, right? Otherwise, Saki would have shown a stronger reaction. But itīs stupid ... he couldnīt have gone far enough to be so lost out of Sakiīs sight to not find him again within seconds. But Saki just went all "whatevs" and journeyed away. :|
