「追想 a diary」 (Tsuisou)
"Remembrance"

This was a pretty 'quiet' episode by Guilty Crown's standards, which is both a good and a bad thing. First, the good: exposition is never a bad thing. Next, the bad: this is the lead-in to the penultimate episode - not a good time for an info-dump, especially if it's something viewers can piece together themselves.
