Heartwarming / Luigi's Mansion: Dark Moon

• How the Toads react when Luigi frees them is always pleasant, especially the first Toad, who hugs Luigi and calls him his hero. Luigi even gives the little guy a pat on the head.
  • Also, when you reunite with one after solving a puzzle, he and Luigi high-five.
  • The Toad you rescue in C-5 is absolutely psyched to meet Luigi, showing that Luigi does indeed have in-universe fans that adore him.
    Yellow Toad: Lu-Luigi?! THE Luigi? AAAAAAH! Um... It's an honor to finally meet you, sir. I'm a huge fan!
• The. Entire. Ending. Full stop. Why? For many reasons:
  • Luigi's reaction to having saved Mario. At first, Mario just pops out and gratefully thanks Luigi for it, even calling him "Number one", to which Luigi replies with a shy, hesitant "I-I did it?" like he can't believe he did it. Shortly afterward, as they watch the Dark Moon return to the sky, Mario gives Luigi a pat on the back, giving us a proud "That's my bro!", to which Luigi replies with a quiet "Th-Thanks, M-Mario...!". Luigi is Adorkable incarnate and you will love every second of it. Mario has an amazing little brother, and he's very proud of him.
    Mario: "Ha ha! Ah, Luigi! You saved-a Mario! Way to go! Number 1!"
  • This games holds one of the few times Mario has gotten scripted, voiced dialog that wasn't just re-used from a past game, making the above reunion with Mario and Luigi even more of a special moment.
  • A Greenie takes a picture of Luigi, Gadd, Mario, the Toads, and some ghosts. Luigi is in the center and Mario is off to the side. He's had his ultimate shining moment, and he hangs the photo on his wall.
  • Three words: "Come here, doggy!". Not only has Luigi learned to befriend ghosts, not only does he forgive Polterpup for messing with him before — he adopts him. That's right, Luigi adopts a ghost — and they look just absolutely happy together.
  • Finally, as of this game's end, it seems Luigi has finally — if only mostly — kicked his fear of ghosts. Luigi has not only proved himself a true hero from Luigi's Mansion until now, but overcame his own phobia by facing it head-on through sheer willpower to save his brother first, and the ghosts that King Boo drove amok this time. This is not just heartwarming in the development of his character, but doubles as an incredible Moment of Awesome.
  • All of the ghosts are so cheerful after the Dark Moon is restored. Among the ghosts shown changing back is a Slammer chewing on a Greenie's head. After regaining its senses, it realizes what it was doing and spits out the Greenie and proceeds to cuddle it.
  • Just seeing Luigi, Mario, and E. Gadd playing with the once again friendly ghosts is Sweet Dreams Fuel by itself. From Mario being picked up by a Slammer to E. Gadd being "Hip hip hooray" tossed by a few Greenies to even the Toads with one of the Possessors! And to cap it all off, Polterpup.
• Before the second-to-final mission, E. Gadd tells Luigi:
  E. Gadd: Look, Luigi. If you...uh...don't ever come back. Just know...
  (beat)
  Just know that I'm very proud of you, my boy. Very proud. *sniff*
• An image in the end credits shows Mario and Luigi giving each other a high-five.
• Luigi's reaction to getting a 3 star rank. He looks like he can't believe his eyes, then he does a little dance, hops, and claps his hands, all with a big smile on his face. Seeing him feeling proud of himself always feels good.
• After you recover the water system in the Haunted Towers, the water starts flowing everywhere as massive currents, and you can see Greenies hopping in and playing, as happy as they can be.
• After the fourth infestation mission, E. Gadd says that it can't be a coincidence that they appear at the places already explored and that someone must be orchestrating them. But he immediately follows up by stating his confidence in Luigi.
  "But with you on the case, Luigi, those ghosts don't stand a chance."
• In the cutscene just before facing off with King Boo, E. Gadd is absolutely horrified when the dark moon piece comes back without Luigi. Even with some of his more sarcastic remarks throughout the game, he really does care about Luigi's well-being.
