46) Night
It had become more and more frequent until it started happening every Saturday night, with the punctual continuity of a ritual but nowhere as sacred. Morty was accustomed to being woken up by the laughter of ghosts around midnight. But these shrill and incessant laughs did not come from a ghost, and had nothing eerie or foreboding about them.
Morty shifted in his bed and tried to decipher the sounds. Yes. He was doing it again, as he had been doing every Saturday night. What crazy idea made him do these things in Morty’s house? Morty still had no clue, and he was starting to think that he was being overly tolerant of his friend’s practices, having never intervened during any of their occurrences. As usual, Morty’s excessive patience was being abused.
Tiredly, he got up from the bed and walked out of his room in the near darkness. He reached the room his friend was celebrating in. As always, the door was locked. Morty knocked loudly, shouting over the laughter while trying his best to sound intimidating.
"I’ll only say this once, my good friend… Please find somewhere else to party at, other than here!"
Suddenly, the laughter ceased, and the door opened slowly with a sinister creak. His friend appeared at the doorstep, gazing at Morty with his usual, knowing smirk.
"Just because you’re my best friend," Morty continued, his voice now calmer now that his friend was listening, "It doesn’t mean you can do anything you want in my house!"
"Maaan, you’re SO boring!" The friend exclaimed, bursting in a fit of coarse laughter, laughter soon echoed by his guests inside the room.
"But what about her?" Morty inquired, sighing. "You know it’s dangerous for her to expose herself by coming here…"
"Ah, the gal’s just found a nice place to live in around here." The friend replied promptly, his guffawing toning down to a snicker. "You don’t need to worry about her being caught."
"But she shouldn’t be here!" Morty insisted, looking genuinely worried. "Every time she goes outside, she could be assaulted by a maniac, or a collector! You see, her species isn’t usually found here in the Johto region…"
"She knows how to take care of herself." Morty’s friend interrupted him, turning to face one of his guests, who was now curiously peeping outside the door. "Don’t you, Medi?"
The Medicham nodded and smiled, making a pleased reply in her language. Morty could not understand Medicham speech, but he could tell that was a yes. Soon after, she remarked something to the Ekans next to her, and then burst into that shrill laugh that kept waking Morty up.
"Please, guys… Could you at least try to keep it down a little?" Morty asked, sighing, his will to try to be rigid and exacting with Gengar now completely gone. "I’m trying to sleep…"
"Aaalright…" Gengar rolled his eyes. "We’ll keep that in mind. Although that might be a little hard to do…" He glanced sideways to his companions. "We’re reminiscing the good ol’ times tonight."
That loud laugh again. This was going to be a long night…
"Don’t let me down, Gengar." Morty said with a concerned look, turning to walk back to his bedroom. "Have fun."
"Goodnight, Morty!" Gengar called out with his trademark grin now even wider and more evil-looking. In unison, the Medicham and Ekans bade him goodnight as well, though Morty could not understand them.
"That’s a cute trainer you got yourself, Gengar." Medicham piped up, as soon as Gengar closed the door. "For a human, he seems quite nice."
"You think so?" Gengar snickered. "Keh! Dude isn’t half bad. He’s been helping me get over some stuff… Anyway, Ek, Medi, how are things up there on Mt. Mortar?"
