I'm quite surprised that this episode hardly showed any closure until the end, time which should have been better spent imo. Never matter the end did show some significant development but it leaves me to wonder how the end will be.
Sana x Nanaka development was a real treat to see. Especially dere dere Nanaka, who single handedly proved to me that this episode was not a waste of time (Oh I am weak against all things cute and fluffy...err I mean moe :3).
Well, without the twins the group is now reduced to three members (say, we could really use some Hinako to brighten to mood O.O). And sure enough, the mood around the trio has hit an all time low - everyone misses the twins (I do as well >_<).
Sana x yuzuki vibes...just for a moment
Aoi does her bit in trying to let Sana and Nanaka have their own time. But lying comes at a price - one she has to pay with her boobs. Best mother ever
Well not much else besides the important part happened. Nanaka asks Sana about his watch, but it seems that it isn't yet time for him to reveal the truth.
In the end, Nanaka freaks out at the sun from the cave. As dumb as it may sound the light from the sun looked like burning fire which causes Nanaka to remember her past - fully.
From the preview we see a new member into the mystery. Nanaka's sensei seems to also have some connection with the blaze. Now wouldn't it just be interesting if it turns out that Nanaka's mother was having an affair with her sensei which caused a fight and subsequently the fire to blaze through the house - I doubt it would be this predictable...right? ^^
