Regarding the idea suggested previously in the thread that Okane's Stein Reader is someone leaping his memory after each D-mail, I don't think that quite works. For one, the mind is entirely consistent.. which would mean that someone would have had to have a copy of Okabe's state of mind right before the D-mail was sent every time. That just doesn't sound right at the moment.

I guess one other mystery that has been overlayed and somewhat forgotten amongst all the things happening is why the hell does time stop when Mayuri's about to die? That just makes no sense, and brings back the earlier wasted-planet scene that suggests Mayuri is somehow related to the space-time continuum itself or something..
