Nodoka has some interesting discussion about left-handed people in mahjong. I'm also curious as to who told her about it being better to use her right hand, since it seems to refer to when she first learned how to play mahjong, something that happened before she even came to Achiga. Perhaps a flashback will shed light on this.
Kinue seems to be taking the loss somewhat hard, as I expected. I'm curious as to how she'll feel when, as I suspect, Himematsu gets eliminated.
It's nice to hear more about Usuzan's plans for the future. It seems as though, even if they've accepted that they've all but lost already, the outcome is still within their plans.
It's interesting to see that Teru's attitude toward Saki may be shifting, however slightly, even if she's still not referring to her by name ("It might be tough for that girl, since it will be her second match against Suehara-san") and seems to be making excuses to avoid watching the match.
