Well, there's been a lot of fan art and rumors going around with the two kamui's switched so it wasn't that big of a surprise to me.
I just watched the raw. Is Underwater any good?
So, I get that Ryuko has been a bit off and she's made some very...poor choices, but let's be fair shall we? That poor girl's been through a lot. And, as twisted as this may seem, at this very moment of time she is probably the happiest that she's ever been outside of being with Mako's family.
That being said, I was a bit sad that we didn't get to see Ryuko's transformation with Junketsu. Hopefully we will see Satsuki's transformation next week.
Also, why the hell didn't Satsuki, the Devas, and/or Nudist Beach try and save Ryuko when she got captured instead of going back to the carrier? (again I haven't seen the subs so if they answer that then ignore this)
