For the record, picked up ep 239 Tues night, and just minutes before typing up this review, got to watching it.
Episode begins w/ Muramasa finding the hollow that he was looking for.
Then Tobiume tells Hinamore to wake up an' smell the reality, and that she, Tobiume, takes pity upon her, Hinamore, to put her down like the wounded animal that she is.
Meanwhile, Haineko & Matsumoto continue their cat fight. [Yes, in every sense of the phrase!]
Then the Zanpakutou soon discover they were setup and get promptly taken down. Muwahahaha.
We get a lecture, and then get back to Captn Hitsugaya's confrontation w/ his Zanpakutou, Hyourinmaru. A few moves and counter moves, then the background flashbacks begin. And Hyourinmaru finally remembers. [It's all very poignant.]
The ep ends w/ Muramasa having to settle for the hollow that he ended up with.
Omake is Chad & Ishida having to settle down Kon in Ichigo's body back in the real world.
