Just to clear up any confusion, characters like Red, Blue and etc are aged up so for example:
Red: 19
Blue: 20
Polaris: 18 and etc. Just in case anyone is confused on how old each character is(even though it'd be crazy for an 11 y/o to carry an 18 y/o)
Polaris anxiously followed Red, not really knowing what to expect from going into the pokemon lab. He wasn't afraid, but since his pokemon was a gift, he knew little to nothing of what was inside of a pokemon lab. "Hey Red? Are you sure the professor here will just...give me a pokemon? I...I don't exactly want to be a trainer, I'm only here for school.", Polaris reluctantly said, letting go of Red's hand. Red turned around slightly, having a blank look on his face, but was a little confused from what Polaris said. Shouldn't Polaris be more eager to get a pokemon? That's what Red thought at least. As much as Red wanted to say it was for his own good and how what would he do if his only pokemon was stolen, he barely knew the boy so he couldn't just force Polaris to get a pokemon.
"Right. Just come and look.", Red simply answered, opening the lab door for Polaris and Polaris stepped inside. The lights were dim and it was a little cold, was no one in the lab at the moment? Polaris noticed right away that it was way smaller than the pokemon lab in Kalos, which was way bigger with a couple floors too and pretty high tech. "This...is it? This is the pokemon lab?", Polaris asked, sounding a little surprised and Red nodded. "It...it's nice, I guess.", Polaris muttered, rubbing his arm a little bit and looked fairly disappointed.
"Come on, we need to find Professor Oak.", Red instructed, taking Polaris back outside. Polaris internally groaned, realizing what he was getting himself into. "B-but...Sylveon and I are tired...can't we just find him some other time?", Polaris complained, picking up Sylveon and Red nearly face-palmed. "I carried you the entire way here, how on earth are you tired?", Red began to say before he heard a voice.
"Red? Red, is that you?", it was an older man's voice, Professor Oak! Red quickly approached the pokemon professor, holding his hand out a little. "I can't believe it! You've really matured since I've last seen you!", Professor Oak said, shaking Red's hand, getting a slight nod from the boy. "So, are you here visiting your mother? She must be quite worried about you!", Professor Oak asked, but Red shook his head and pushed Polaris forward. Professor Oak had a slight look of confusion and Red said, "He needs a pokemon." Polaris couldn't help but gulp a little, glancing at his Sylveon for a second and back at Professor Oak. "I…erm…y-yes sir…", he stuttered out, not giving Professor Oak any eye contact and the pokemon professor nodded a little bit.
"I see! Then come with me, I'm sure we can sort out this situation!", Professor Oak nodded, leading the two boys back to the pokemon lab. Polaris sighed softly, sitting in one of the empty seats in the lab and Sylveon sat near his feet. "Sir…? I already have a pokemon…do I really need another one?", Polaris nervously asked, not understanding why he needed another pokemon. Especially since he had no intent of becoming a pokemon trainer! "Hmm? Well, now that you mention…I am a little baffled by the request. Red, why does this young man need a pokemon?" Red glanced at Polaris before turning back to Professor Oak and frowned a little. "He only has one pokemon, I'm pretty sure he doesn't want it to get stolen. That sort of pokemon isn't common in Kanto, is it?" Professor Oak nodded and said, "If you're that worried about this boy...then perhaps you can catch him a pokemon! I'm sure he'll appreciate it." Polaris almost went pale, not wanting another pokemon and he knew Sylveon wouldn't be on aboard for this either. "Alright you two, be careful out there!", Professor Oak waved goodbye as Red and Polaris left the Pokemon Lab, heading out into the tall grass.
Red stuck his hands in his pockets, glancing at his Pikachu then at Polaris, "Why didn't you ask for a pokemon yourself? Now I'm stuck basically babysitting you.", sounding fairly bitter and Polaris looked offended. "I didn't want a pokemon! I don't want to be a stupid pokemon trainer!", Polaris snapped, crossing his arms childishly, "Besides, you don't even wanna do this. Right?" Red looked a little surprised at the way Polaris spoke and Pikachu went up to Polaris, nuzzling him a little. Polaris's bitter expression quickly melted away, picking up Pikachu and Red nodded slightly. "Right...but I mean, it's not really a good thing when the first thing you experience is getting robbed.", Red rubbed the back of his neck a little bit and added, "But I have to ask, did you catch your Sylveon yourself?" Polaris glanced down at Sylveon before shaking his head, "No. Sylveon was a gift...on my 12th birthday. My mom didn't want me to be a trainer, she wanted me to be a nurse. Unlike my dad, who was a trainer...he went to another region to try and become a champion." Red looked somewhat confused before nodding in thought, "A champion, huh? Sounds like a big thing. Hopefully he'll do well." Polaris grinned and nodded, "Of course! And you're a trainer too, right? So that means you'll be a champion one day too, right?"
Red stayed quiet for a second, he was already the champion. Although, as much as he was proud of the title, he didn't exactly like talking about it to others. Besides, Polaris had no interest in being a pokemon trainer so it wouldn't have really mattered. "Yeah...I could be. But it's a challenge.", Red nodded, motioning Polaris to follow him. "Come on, lets go for a walk.", he said, and Polaris and Sylveon quickly followed.
