Hm… This whole chapter proves without a doubt that Kishimoto loves to use symbolism. Why do I say that? What shape was the moon when Naruto was born?
Now what was the shape of the moon when Sasuke left the village?
What was it we saw in the latest chapters?
This isn’t news, really. If you’ve been paying any sort of attention, you knew this revelation was coming. I just thought it was interesting, and i like how Kishimoto is tying everything together.
