It didn't take long for Allister to gather a small crowd. With his playing, and dancing along to the chilling music, before he knew it, spirits were popping up left and right. Not all of them he could immediately recognize, but some lingered just long enough for him to say a quick hello, before they disappeared into the shadows. After a while, he almost had an audience, and was now starting to almost glide around as he played, feeling a newfound energy! His eyes lit up, as they often did when he was excited, or around enough ghosts, and Allister twirled, laughing happily as he played.

At one point, the other person must have walked into the performance, since the door creaked open, unbeknownst to Allister. But when some of the spirits began to fade away, he knew something was up. And then he heard another voice!
*"Um... Hello?"*

"Agh!" The young gym leader shrieked, jumping back. He fell on his knees, causing an ugly thump to ring out from his violin, which scared away his small crowd. They all retreated, as he could feel their presence fade, and he immediately scrambled to pick up everything that he had dropped.
"Aah... Um..." Allister fought to speak, as he started up at this person who had just interrupted him.
"H-hullo?"

A rush of cold hit Zephraxe as the spirits fled, some passing close or through him. That, combined with the scream from what sounded like a young voice, startled the researcher. He stammered a loud swear, nearly jumping out of his skin. 

*"H-Hullo?"*

Zephraxe heard the voice speak and tried to even his own voice before trying to talk. 
"Hey there..." He started with uncertainty. "Uh, didn't mean to spook you there. Sorry about that." He tried to act casual as he stepped into the room, the floorboards squeaking beneath his feet. The small figure came into view better as the man approached and his eyes adjusted to the darkness. 

Zephraxe was certainly on edge, but knew his psychic senses weren't tricking him. This was a living being in front of him, most certainly a young child. But what were they doing here...? He intended in finding out.
Christopher
Who... Was this guy? A man stepped in after all the spirits had fled, and was now staring down at Allister, who was sitting on the floor. He gently patted the pumpkaboo sitting in his lap, and it happily fluttered, before flying off.
"Goodbye," He gently said, waving off the last of his new friends. He then turned to look back at the stranger, who stepped into the room.

Allister's eyes were no longer glowing, and he crossed his arms as he slowly stood up to great the stranger. Another living person... No one told him there would be another living person here.

"You... Ruined... My... Playing!" Allister snapped, stomping his foot on the ground. "You s-scared em off!" He usually wasn't anywhere *Near* This aggressive, or whiny, but meeting ghosts was one of his favorite pastimes, and who knows how long it was gonna take to get them back!
"I-I was... Um... I was about to make friends!" He complained. He tried to stay angry, but was more frustrated than anything.
"Agh, thanks for spooking them... P-pun, *Not* Intended." He huffed. Looks like someone caught Allister in a bad mood today.
Brian
Zephraxe blinked as the kid began to have a tantrum. This was certainly a strange turn of events. He questioned for a moment whether or not this was even real, but he knew better. His mind wasn't so easily influenced. He shook his head slightly and raised an eyebrow as the child continued to speak. 
"Well... I'm sorry about that. I had no idea that's what you were doing." He crossed his arms and regarded the kid. "I was quite spooked myself to hear a mysterious violin in a place like this." He glanced around in the darkness, then returned his eyes to the kid. "... Are you okay?" He asked. Zephraxe wasn't entirely sure how to handle this situation, but being friendly probably was a good idea.
Christopher
Maybe he should calm down. As much as he was angry about him scaring off his potential friends, Allister was able to take a few deep breaths and calm himself. His eyes flickered before fading out, and he shook his head to clear his thoughts.
"Aah..." The young gym leader frowned, tucking his violin under his arm and looking up. "Well... Um... Y-you see. I was playing for the spirits. G-ghosts like music. Um... Their... Um-curious nd all. Music makes em wanna show themselves." He explained himself, not exactly sure if this random guy would even want to here him ramble about the dead.

Allister awkwardly giggled, shuffling his feet on the floor. He just kinda shrugged when the man asked if he was okay. "'M fine. More w-worried for the spirits. Hope they aren't scared," He said. "You? Umm... Okay?"
Brian
Zephraxe tilted his head slightly. This boy seemed to know quite a bit about the spirits and Pokémon here, because it was obviously filled with Ghost types. 
"Huh... Well, I'm fine myself. A little on edge, you know? The energy here doesn't exactly agree with me... But I'm here regardless." He shrugged. "Doing my own research." 

The fact that the boy's eyes were glowing did not escape him and it made him all the more curious. The kid was well acquainted with the undead. Perhaps he knew something Zephraxe did not. He leaned against the wall behind him and took a deep breath. "I'm Zephraxe, by the way. I'm a Pokémon researcher." He gave the boy a smile. "And you are...?"
Christopher
"Allister... Fr-from Galar. Um... As in, 'm from Galar." He replied, very quietly, as he was finally completely calm. Unlike the man in front of him who seemed to be on edge. But wasn't that always the case for people around the dead. 

"Z-Zephraxe?" He asked, gently tipping his head to the side. Did he have that right. "Research?" What research was there to be done here. It was just a tower, and a small one at that. And why didn't *"The energy agree?"* As he had put it. Was this man *That* Unfamiliar with ghost types? Strange.

"Th-there's... No reason to research this place..." Allister slowly stated. What would anyone find here anyways? Unless they thought getting stories from the dead was research. But that didn't take a scientist. At least, the boy didn't think so. *He* Certainly wasn't one.
