Luigi hadn't been sleeping well.
In his defense, could you really expect him to? It hadn't been that long since he'd fallen down that pipe and nearly died at Bowser's attempted wedding.
One could forgive him for maybe falling out of a healthy sleep cycle.
Still, he found himself regretting every second he'd been asleep or awake at odd hours as his body convulsed beyond his control. Lack of sleep had always made his tics worse- He knew that- And now he was paying the price for it.
It was two in the morning when Mario was awoken by a shout at the other end of the room.
"Luigi?" he asked, concerned for his brother's wellbeing. "You okay?"
"Mushrooms!" Luigi shouted involuntarily as he writhed around on his bed like a mealworm under extreme heat. "Mushrooms! Coins! C-C-Coins!"
Mario frowned, realizing what was likely happening as he turned the bedside lamp on. Luigi managed one miserable look at his brother before his neck jerked away.
Luigi had developed Tourette's at a young age, so Mario had long ago learned what things helped with his brother's tics.
He pulled out his phone and began playing peaceful instrumental music, then walked over to sit at the edge of the twitching man's bed. He knew better than to get too close, as that could sometimes worsen Luigi's tics, but he was near enough to where his brother knew he was there. He wasn't going anywhere.
Eventually, the tics began to die down and Luigi groaned in exhaustion.
"Bad one?" Mario asked, looking back at his brother, who just nodded. "'M sorry, fratello"
"It's okay" Luigi sighed. "It's my own fault for not sleeping enough"
"Do you want melatonin?" Mario offered. They had a giant bottle of the stuff in their room for whenever either of them couldn't sleep. Luigi nodded weakly, whimpering as that triggered another tic in his sore neck.
Mario got up and grabbed the bottle of pills, poured a few out, and brought them to Luigi, who gratefully took them with the water bottle on his nightstand.
"Thank you" the thinner one said.
Mario smiled and tucked him into bed before returning to his own and promptly falling back asleep.
