Misty's day of Nothingness
It was a fine morning, Misty was feeding all of her pokemon when she fell into the gym's huge pool and was immediately shot back up to the surface world by gyarados. She continued to spend her afternoon by the pool where she trained her pokemon.
Later in the day, a trainer came by asking for a battle, so Misty said yes. Since it was a one on one battle she was going to choose gyarados, but she accidently tossed psyduck's pokeball, because she couldn't change the pokemon, she lost within seconds to the opponent's caterpie... It was humiliating for Misty, especially since she lost to a bug.
After she finished steaming over her loss, she went out of cerulean to the lake to fish. Once all her gear was set up, she felt a tug on the line, she pulled it up only to fine it was a metapod. Disgusted, she attempted to throw the bug pokemon off, but it wouldn't budge and it latched itself to Misty using string shot. After several minutes of freaking out and screaming, she finally managed to get it off, throw it in the lake again and run back to the gym where she went to bed.
That night she had nightmares about giant bug pokemon. She woke up several times at night because of this she didn't bother going back to sleep and went out. She went to the nearby cafe trying to get a cup of coffee, what she didn't know was the theme of the night was bug pokemon. So you can guess what happened when she entered.
Later that day Ash came by the gym, after a long conversation Ash tried to kiss her, she would have kissed him back, but gyarados decided to send him blasting off. Now she was worried because he thought she ordered him to, so now he thinks she's not interested so then she became sad. She went to bed and cried herself to sleep.
