Easily

Chris's eyes grow wide with surprise as he realises you have a pokemon that can battle, and Danny's smug face contorts into a look of frustration. It soon becomes pretty apparent why; despite the best efforts of Chris's Rattata, the guy clearly has no idea what he's doing as a trainer, and all your years of study pay off as you flawlessly command Charmander, who now thankfully seems willing to listen to you, to pick up your first victory, your fire lizard easily dodging Rattata's predictable attacks before finishing it off with a few scratches.

Pride surges through you at your accomplishment, and you momentarily forget about your deal with the shady mart man. "Yes! We did it, Charmander!" you cheer, joyfully embracing your pokemon as you both celebrate your first win. The heat of its body is a little too much for you since you're already pretty sweaty from the running earlier, so you let it go pretty quickly before turning to the two bullies who have helped Blue to torment you for years now. "What did you guys call me earlier? A slut? A bimbo? How does it feel to get your ass kicked by me?" you gloat, the sense of payback feeling incredible.

Chris returns his Rattata to its ball and glares at you before immediately turning on Danny. "What the fuck, man?! You said her pokemon would be knocked out!"

"Shut up, dude!" Danny snaps back. "You're the one who went and got beat by this whore!" He turns on you. "I'm up next, bitch. That smug face of yours is gonna look a whole lot different after I'm done with you!"

Despite his tough talk, however, Danny proves to be no more competent than Chris, his Pidgey being pretty easily handled by you and Charmander. Two straight wins feels pretty damn awesome, even with the dread of what you'll have to do after the battle sitting at the back of your mind.

"Ugh, this pokemon sucks!" whines Danny, kicking at his **** Pidgey on the ground.

"Stop that!" you yell at him, hating to see such cruelty towards an innocent creature. "You lost, you can't take that out on your pokemon! Maybe this will teach you to go preying on girls just to get laid."

Danny scowls at you. "Ugh, whatever, bitch. Just you wait; Blue is gonna be Pokemon Champ one day, and when he comes back home to Pallet Town we'll all celebrate by taking turns fucking you! C'mon, Chris, let's bounce!"

The two lowlifes walk off back towards Pallet, Danny leaving his wounded Pidgey behind. You recall your Charmander to its pokeball and hurriedly run over to the poor bird pokemon, cradling it in your arms. With the brief victory high gone, you're reminded of what you agreed to do to heal your Charmander, and its clear that your 'helper' hasn't forgotten either. "Hey, looks like you got a new pokemon out of that encounter, too," grins the mart man, striding out from behind the tree and gesturing to the Pidgey in your arms. "Reckon that's gotta be worth that 'payment' you promised me, huh? Hell, I'll even heal that one up for ya too, free of charge."

You briefly consider running away; the mart man doesn't look particularly fit, and it's not like he actually beat you in a battle, you're perfectly within your rights to not consent to whatever he wants you to do. However, while he may not be in peak physical condition, you've recently found out that you aren't either, and if the run here from Pallet turned you into a sweaty mess, there's no way you'll be able to outrun this guy all the way to Viridian. There's almost no chance you'd be able to fight him off either, as he's a fair bit taller than you and a grown man.

Nope, you're just going to have to do what he says for now. He gestures you over with his finger, and you obediently walk towards him. This isn't how it was supposed to be...
