* Hikari [[UnexplainedRecovery coming back from the dead]] makes a lot more sense when you realize her InTheNameOfTheMoon speech refers to the heart and wills of light (i.e. the Heartiels) becoming one, but makes no mention of the life of light (i.e. Hikari herself.)
* Marble Screw could refer to marble cake, a mixture of vanilla and chocolate cake, which are white and brownish black respectively.
* When the Evil King describes what the darkness is and you realise that if the defeated minions retained their consciousness, they are stuck in NothingAfterDeath.
