The fanservice in this episode skyrocketed beyond heavens.
Of course, Saeko's fanservice topped the first place because she got lots of cool shots onscreen fighting with her boken and sword-fighting, awestruck techniques coupled with those irresistible fanservice shots of hers.
While, I think Marikawa-sensei's bared nude shots became over the top due to the fact that she did not realize she was naked, until Saya told her so.
Anyways, while this episode wasn't superb, nonetheless, it delivered a powerful pack of humvee steamrolling, gunshots, sword blows, Takashi's dare rescuing, and solid emotions.
Spoiler:
Takashi engaging in conversationg with Saeko to take or not action upon rescuing the distressed survivors presented the ethical issue: sense of humanity v.s. survival instinct rationale.
I felt like a kid, therefore, I did take Takashi's stance about doing something for the survivors. However, as an adult I have to learn the hard way (just as Takashi has to come to terms and to accept his new reality) that being responsible means looking at the worldwide picture beyond the scope of each one's personal worlds and views.
Logic dictates that there wasn't enough room and food to sustain a large number of survivors were Takashi and, the Scoo-, I mean his group were staying at. Having turned the lights on and risk the neck at attempting to fetch as many survivors as possible would have quickly compromised the safety of their location and their lives.
1. 'Them' were too dangerously close right at the corner of their residence and flocked the streets in great numbers.
2. The streets were packed and tight in most places.
3. There was no guarantee that any survivors around the vicinity wouldn't have snapped or eventually drown in hysteria or psychosis compromising further the stability and lives of the overall group.
Hence, I have to admit that Saeko's rationale comes from the general view regarding to stay fit and with a cold mindset in order to endure the trauma and keep oneself alive, however, she made it clear that she bore with that judgement because hated it at being the right decision.
Which brings me to the subjective matter regarding the groups' feelings at the sight of the defenseless survivors.
I nearly broke down when the pinky-haired girl's father was stabbed to death by the residents of the house across the street.
OK. I have to come to terms that those people did what they should to survive. They couldn't let other living people in because had their judgement blocked by fear, specially with 'Them' too close and in swarms.
Nevertheless, I believe those people went overboard for what they did to the girl's father. If they had either stabbed or shot him before the Father got any chance to knock at their doorstep, then I would have understood. Instead, they opened him the door and quickly stabbed him on sight.
No matter how much explain or rationalize their actions it was disgusting. The Father was led to a false sense of hope and got killed upon her daughters' eyes.
I think this is what incensed Komuro and urged him to go for that girl's rescue.
