* Why do the tropes keep insisting that [[spoiler:Shiro didn't have multiple personalities]]?
** Maybe I missed something and so I won't go and edit everything (also, I'm very, very lazy), but despite [[spoiler: her]] statements near the end, [[spoiler:we repeatedly saw Innocent Shiro's thoughts during Ganta's stay in Deadman Wonderland and they seem to be far different from how the Wretched Egg behaved. Even assuming that it wasn't an inaccurate/incomplete translation or Original Shirou/Wretched Egg lying to Ganta to make him more willing to kill her, we still saw her work on her Branch of Sin while alone (IIRC), which she wouldn't need to do if she had the memories of the Wretched Egg, and we even saw multiple Shiros in her very mindscape, one of whom was confused by what was happening. Heck, we even saw her Wretched Egg personality appearing during her initial testing period, apparently to take all the pain that Original Shiro couldn't handle. I guess its possible that Innocent Shiro still has a subconscious link to her other personalities, which would explain why she knew Ganta was there, assuming that the Director didn't tell her for the sake of seeing what she'd do, but that Shiro didn't seem to be the Wretched Egg unless something happened to the Mother Goose system, at which point she pretty much instantly shifted over (as Yoh found out when he accidentally got a bunch of guards slaughtered by Wretched Egg Shiro when he tricked them into shutting off the power in that area). Barring this being a massive retcon or deliberate misinformation from a DeathSeeker, it seems more likely that Shiro managed to reintegrate her personalities as she started forcing her way past Mother Goose's lullaby.]]
* Why is the Mother Goose system a problem for Hagire?
** Yes, the key is tricky, but we already saw that shutting off the power at least turns off the local Chorus Boxes, and [[spoiler:flat out destroying the core worked perfectly well once Shiro got access to it]]. Is there any reason why just blasting at the main node with technology or Branches of Sin wouldn't work fine? Heck, coat it in butter and call in Masu, if you want a joke ending.
