Limit drama: Episode 5 screenshots and recap

The five current survivors....
Nanami Sakuraba as Mizuki Konno, one of the elites.
Ayano Kudo as Haru Ichinose, the other elite.
Tao Tsuchiya as Chieko Kamiya, a loner who is the class brain.
Yuka Masuda as Chikage Usui, not sure of her status but doesn't like any of the survivors, another loner.
Rio Yamashita as Arisa Morishige, the class outcast.

 Last episode our 5 were still searching for a possible sixth survivor however the 5 may have turned into 4 as Usui after a scuffle with Morishage had run off with her sickle, now 3 of the 4 are out searching for her. But their search was futile as far as finding her but they did find something else.... the 6th survivor! And this was a male who before the crash had got thrown out of a window on the bus and had ended up far from the crash, also he was one who may have had a crush on Konno or at least she was thinking he did before the crash. Besides those two happenings, the discovery of another survivor and the hunt for Usui not all that much happened with the group except that the fire they kept going in the cave got out of control and burned much of their meager food supply.
 Meanwhile back home the search for the survivors has been going nowhere, the school, mainly the principal, is still covering up much of what they failed to do namely keeping in contact with the chaperone and notifying the police of their disappearance. The police have finally started to search however not where the crash happened, the survivors ended up near Shizouka and the search is going on nowhere near that area, they weren't supposed to end up where they were.
 That's it for a mini recap, it was a solid episode but not as good as the first 4, noticed that's a trend in most dramas, the beginnings and ends are very good but usually an episode or two in the middle tends to be only so-so, guess you could say that about this last show. So will the next episode get back on track, still many questions that need to be answered, will they ever find Usui, will the police keep searching in the wrong location, etc? Answers to a few questions are in the next post for episode 6.
