Verity: We don't own the franchise, as our hostile takeover failed. Miserably.

Ever since the summer, he had heard the voices in his dreams. Not just since summer, since fighting the spirit of the Dream Stone and his giant robot. The voices had helped him, then. There was a Luiginoid assigned to each of them.
He wasn't sure what the voices were. Whether they were parts of his own subconscious, or voices of other Luigi's beyond time and space, or a mixture of the two, the things they said were entirely correct, or at least, they had been, at some point. Almost of them were true even now. As the voices lost the points they'd proven, they'd fade, and be replaced by others.
One of the voices, however, would never fade. It told him one thing that he would always take to heart.
'Help Big Bro!' And he would. No matter what.

When he'd explored Dream's Deep, he'd heard the voices. And he never forgot. How could he? Every other thing the voices said, they had mentioned him. He had never imagined that his little brother, who could put up such a fuss when the time came to rescue the princess again, didn't actually want to be left behind. He had only stopped asking because he kept getting 'no' for an answer. Although... if he asked now, would he get a positive answer?
Yes. He would.
Of the entire experience, the ending had been the one he'd remember forever. All of the voices had merged together, and told him one thing.
'We're all here for you, Bro. Always.'
And he'd do the same. Forever.

The voice was something to be ignored, and maybe it would go away. He kept telling himself that. It never came true, as much as he could live without the thinly veiled insults towards himself and his friends.
Time passed, and he eventually had to admit to himself that the voice wasn't going away. If anything, it was louder, most likely annoyed at being ignored. So he got used to it. He grew accustomed to the mocking and idle threats, and the voice became a part of his life, if one he could certainly do without.
One day, the voice said something that wasn't hurtful. 'I have a name.'
There was nobody nearby, so he felt it was safe to speak out loud. "So, what is it?"
A moment of blissful silence, before the voice spoke again. 'Mr. L.'
Mr. L proceeded to call him an idiot. He went ignored.

Waking up to find yourself camping out in someone else's brain is not a fun situation. So, when learning of his new living conditions, Mr. L was not pleased. And considering what he had been waking up from, that just made things worse.
He needed to satiate his boredom somehow, so he started with small insults. He was ignored. He knew he was heard, just that the other didn't think it was worth a response.
The other was named Luigi, and he was the man in red's twin brother. Learning that did not help his mood at all. He won a bet, but had no way to collect his reward. He saw his acquaintances again, but couldn't say anything to show he was there.
He voiced none of that.
Luigi didn't know he was the one who stopped Dimentio from casually annihilating his personality along with his free will. He'd never tell him, either.
Eventually, he began to feel slightly less bitter. The insults didn't flow quite so easily anymore. He decided to introduce himself properly.
For just one moment, he was acknowledged.
