Akiba changes presumably because of what Faris sent to the past, and Okarin gets the real confirmation of what happened to Ruka and the D-Mail he originally sent some episodes ago. The episode finally allows us to breath a little after some fairly intense episodes and we even get such a sweet scene between Okarin and Kurisu... or so we think. Something looms in the distance and it may have to do with the D-Mails.
