I only have internet for a couple of minutes so I'll do this really fast
Thank you Ciyanihough for this awesome idea :D

You and ash were walking once again bored as you guys could be.
Ash decided to be an idiot and throw some rocks at random Pokemon.
"Ash stop!" You scolded. Finally ash stopped, but it was too late. The Pokemon started to attack you guys.
" ASH WHY DIDNT YOU LISTEN To ME!!" You yelled as you grabbed your eevee and ash grabbed pikachu. You guys ran as fast as you could.
Apparently one of the Pokemon was a FIRE Pokemon! And of course he used that ability to try to burn you. One of the Flames almost reached ash as pikachu swooped up and electrocuted the Pokemon. The good thing is that Idiot Ash wasn't hurt. The Terrible thing was that pikachu was.
"PIKACHU!" You and ash yelled at the same time. And in the same time a girl was riding her bike by us. "Hiwehavetouseyourbikebye." Ash said rapidly as he took the girls bike and pedaled off with pikachu. " HEY! Give me back my bike!" The girl yelled chasing after ash.
You followed.

You waited in the hospital waiting room with ash. You guys said nothing during the whole time. Nurse Joy came out with pikachu and ash rushed over to pikachu. You could hear Nurse Joy scolding at ash. In the same time, the girl barged into the hospital. She pointed at ash.
"YOU! What did you do to my bike!?" She yelped. Ash gulped nervously and brought out her broken bike that he damaged.
He really broke it bad.
"MY BIKE!" She yelped. You huffed and kept on petting eevee, who was sleeping on your lap.
" I'm sorry, I really am ill get you a new one." Ash said nervously.
" YOU BETTER!!" The girl yelled at him. You decided enough was enough and stood up and defended ash.
" hey, he was trying to save his pikachu." You said calmly, trying to calm things down.
" I DONT CARE ABOUT HIS PIKACHU! WHAT ABOUT MY BIKE!?" She screamed. You couldn't contain your anger anymore, this girl was being a real jerk. " listen up brat, he was trying to save his pikachu because he loved him, it's a boy and his Pokemon relationship, his pikachu could have died and we are here worried about him, meanwhile ash is grieving over his friend, taking the fault for everything, but you just had to ruin everything with your stupid bike business, ash and I will personally buy you a new bike if you can shut up!" You snapped.
Ash looked surprised. You and the stranger girl just had a glaring contest while everybody else in the room was like, 'oh snap.'
The girls face softened, " I'm sorry, you are right I'm making a fuss over nothing." She says with her head hanging down.
You and ash look at each other and smile. "It's fine." You said giving the girl a warm smile.
She returned the smile back to you.
You shook her hand. "My name is y/n." You said.
"And my name is Misty."
