[330] In the Christian era, Moloch - actually an ancient Phoenician god - was demonized as a thief of children. Church historians noted that the pagan Phoenicians (who, like all pagans, were misguided souls fooled by demons from the Church's point of view) sacrificed children to Moloch in fire. He does not appear in the In Nomine canon, wherein Lucifer has no friends.[474] I cannot save you; / I can't even save myself.
[493] Another Celestial Superior specifically invented for this storyline (and whose mortal guise, obviously, is Jacqueline Natla).
[503] The Malakim are the choir of angels who are most directly responsible for taking the War to the enemy. Alone among angelic choirs, Malakim cannot Fall - but they can get pretty confused.
[538] Two of the bands of demons to be found in In Nomine. Calabim, the Destroyers, specialize in mayhem and damage; Balseraphim, the Liars, are experts in deception, to the point where they find it almost impossible to tell the truth.
[728] The Elohim are the choir of angels tasked with dispassion and negotiation. They can calm others, but suffer dissonance - enough of which can eventually lead to a demonic Fall - for forming emotional attachments of their own.
[1359] It's mainly down to Truss that Shinji reappears this way; I couldn't think of a decently dramatic way to use him, and I wasn't going to reintroduce him just to have him in the series, but Truss came up with the whole SEELE recruitment angle and followed through so well that he convinced me it was the way to go.
[1514] The entire Bonus Theater!! experiment was fully justified by the excuse to use the phrase "classically trained Shakespearean penguin".
[1643] Repeatedly.
