History Fridge / LuigisMansionDarkMoon

* Before fighting Boolossus/Big Boo, [[TrickBoss it's shown as the "Area Boss" of the final level]]. However, After you beat it, it's shown as a normal level. Plot-wise, this level Luigi and E. Gadd believed they were ambushing King Boo, but instead got ambushed themselves. Gamewise, it appears as the world's boss, but instead was just a normal chapter. Considering King Boo is a master of illusions, it's possible that the previous BOSS Template for the mission was also an illusion, only this time, instead of just fooling E. Gadd and Luigi... [[TheFourthWallWillNotProtectYou He was also fooling YOU]].

* At first, the ghosts seem rather different, having only solid colors and glowing white details. But then it makes complete sense- all of the ghosts in the first game were paintings of Vincent van Gore's. He's not remotely involved in this game, and so all of these ghosts, who are "natural" ghosts, would obviously look different.

* [[CaptainObvious People become ghosts when they die.]] King Boo has the ability to control ghosts. What, exactly, was going to happen to Luigi if he died?

* Early in the game, E. Gadd mentions that he "should have gone to (Luigi) first". At the time, you probably think it's a throwaway line poking fun at Luigi's ButtMonkey status, but later you find out that [[spoiler:Mario has been captured by King Boo again]] and the meaning becomes clear.
** This becomes Fridge Awesome when you realize that [[spoiler:Luigi succeeded where his brother couldn't]].
* Sometimes, when you're being Pixelated somewhere, there's pixels in the stream that are a different size and color then the ones that Luigi turns into, and they're traveling at a different speed than the Luigi pixels. This turns out to be foreshadowing that [[spoiler:King Boo is fully aware of what Luigi and E. Gadd are doing, is watching their every move, and has the ability to mess with the teleporter.]]

* In this game, [[spoiler:beating King Boo involves looking at him so he stays in one place, because he's a Boo.]] This could be an ironic reference to his line in the original where he says that he'll [[spoiler:"fight you like a true Boo."]]

** E. Gadd has said he worked in the area for a while, alongside all the Toad assistants, and the Ghosts pacified by the dark moon seem reasonable enough to have interests or organize their possessions in a clean matter, so only E. Gadd really abandoned any of the places while the Toad assistants kept working hard until King Boo portified them.
