They got out hopes up by implying Kolat in the title then failed to deliver. So it's pretty impressive that the story was so enjoyable despite that disappointment.
It really felt like they were setting up Toturi to write someone else's name instead of Shoju's. It would have gone against his characterization thus far, but breaks from character happen during extreme situations and there's not situation more extreme than this. Still, I don't think he did despite them ending somewhat ambiguously in that regard.
