This is a pure sleuth episode which finally reveals the identity of John Walker. Its fast, perhaps too fast, but gets to the final solution. I personally feel that the pacing of some episodes is to frenetic and the story could of been drawn out, on the other hand that could be language related as well. Many clues are in the language used, which does not translate as well. While we solve the john walker mystery, the bigger mystery of what is the Mizuhanome and how does Kiki fit into the whole thing. I could make a guess, but as my guesses are often wrong I will instead offer the advice that the only way to know the future is to live it.
