A lot of Kazumi and Shizuku flashback. I wonder what the little Alice meant? Maybe Medusa is causing Kazumi's memories about her and her sister to be wrong?
I wonder if Kazumi is actually in the sleep pod inside the monster, and just projecting herself outward without knowing she's in the sleep pod. And Shizuku never really existed. That's my crazy, far fetched theory at this point. So far this series is above and beyond what my expectations were.
