"I AM MR. L!"

Luigi opened his eyes. He looked around frantically. However, all he saw was an endless room of jade. He rubbed his head and tried to think. Mr. L? Who is that? And...Was that my voice!?

An image flashed through his mind. He was with his friends: Mario, Peach, and Bowser. Count Bleck and Nastasia were across from them on the other side. The former was tattered and beaten while the latter was unconscious. The chaos heart was hovering above them, as well as Dimentio. Some words were spoken, though Luigi couldn't make out what they were. Just distorted dialogue. He could've sworn that he felt his own lips moving during some of it.

Then everything returned to jade. I should be with them right now, but I can't. Dimentio has gained control of my body somehow. What should I do?

Luigi didn't have much time to think about it. The next thing he knew, he felt himself being pulled away by wind. No, not wind. Some greater force, more powerful than a black hole. He screamed and heard it echo off the walls of this strange room. It didn't even seem like it was him. Then everything turned to darkness. Luigi's mind became murky and vague. It was like paint, black and green swirled together without any thought or care.

Someone, help me.

Luigi woke up from his dream sweating and panting. He tried his best to calm down. He glanced around. The room was dark, but it wasn't like the endless room of the past. This one had a bed that he was in right now, a nightstand, a dresser, and pictures of his friends on the wall. The only similarity was that there was green everywhere. Black and green.

He sighed. He had never been more grateful that he stopped sharing a room with Mario in his life. Luigi hopped out of bed and felt soft carpet underneath his feet. The man went to his bathroom, which was only one door away.

He turned on the lights and sat on the edge of his bathtub. Luigi had no idea why he was doing this. Maybe he just needed to get away from bed. He took a deep breath. He grabbed a green cup and filled it with water. Then he drank it down. After he had calmed down a little, he tried to recollect his thoughts.

This wasn't the first time he had a nightmare. Ever since Castle Bleck and the near end of the world a month ago, Luigi had been having horrible dreams at night. They would always involve the mysterious Mr. L, which Luigi was tricked into becoming. Mario had told him everything...Twice. Anyway, he couldn't stop thinking about it. He had no idea what that other side of him was doing, but all Luigi knew was total loss of control.

Of course, he hid this from Mario and the people he loved. He didn't want them to be scared of him or worse. Luigi rubbed his hand under his bangs. Sometimes, he still turned into Mr. L to this day. Although he was trying to gain control of it, his efforts were fruitless. Surprisingly, he wasn't the only one who hated this. Mario told him that after he let Mr. L know who he really was and showed him proof, he was so angry that he marched back to Castle Bleck and demanded that that Nastasia girl erase him. She said that she couldn't without Dimentio, but he was always welcome to come back and stay for a bit. It was a generous offer, but it didn't help much.

He cursed under his breath, something he rarely ever did. "Shit." Then he saw something bright green out of the corner of his eye. His razor.

Luigi grabbed it and stared at his arm. He looked at the horizontal scar that was already there. It was from last week, when he had a similar nightmare. He ended up forgetting those morbid dreams, but they were traumatizing at the time. He frowned and held his skin down. 3, 2, 1. Luigi tried to cut himself. Nothing. The second time, his skin turned red. The third time, he drew blood.

Luigi closed his eyes and took a deep breath. Relief. Satisfaction. He was supposed to be disgusted with himself, but he wasn't. He would be in the morning, but that didn't matter now. This was why he did it. Escape from the pain. This was also why he didn't tell Mario. He was always smiling and happy-go-lucky. He would never understand.

Now, he had two scars. Even they reminded him of his brother. One under the other. Two twin brothers. One never seen without the other on top, dominating him and wowing everyone. "Better make it three," Luigi thought aloud. He made one more scar. Then he decided that was enough for the night. Of course, he wouldn't forget the euphoria. He would do it again later. Maybe tomorrow. Maybe the day right after. Maybe next week.

Luigi yawned. With that, the man in green turned off the lights and went back to bed. If only that was the last time.

Headcanon: Luigi only curses if he's angry or frustrated and that doesn't happen often.
