(Note: Episodic notes are still mostly to be found on the Episodics Notes’ page, but up to a couple every week will have their write-up appear on the main page, when I think they warrant it. For those who don’t know, I take the notes as I watch the episode, and merely re-order them afterwards.)
Last episode made it pretty clear, the riddles don’t matter as much in and of themselves, it’s the same situation as House M.D. – the riddles are there to create tension. Shibazaki is a mirror image of Nine and Twelve, he wants to be like them, but he already is – both sides only gain validity via the other.
Nine and Twelve used Shibazaki in their riddle, they’re reaching across, they’re connecting. And likewise, Lisa is making contact as well.
Thoughts and Notes:
1) Here’s something I didn’t think about last week, Lisa asked Twelve if they’re going to destroy the whole world, right? I didn’t think about which answer she’d rather hear, this ostracized girl with no connections.
