Eevee's Evolution

Before
As the ghosts came out at night, Eevee kept hearing about "sex" and no-one would tell him what it was. He would soon find out. Banette even gave him the nickname "Pup.". It was very boring around the gym for a few days, so Eevee had a lot of time to think, and decided he wanted to become an Umbreon. This way he would be like Nuel. Pup told her, and she liked it. MetaLucario told him that to be an Umbreon, Pup had to be happy at night. Pup wasn't so sure about evolving, (What would his parents think!?!) and tried not to be too happy at night.

Climax
On the night of June 10th, Pup was hanging out with some of his friends (not on twitter, one of them being Sarah) in the Outskirts of Virdian City. Except for Sarah and Pup, everyone had to go home for the night. Pup talked to her for a while, when she recommended that they play "a game". She ended up having sex with him, and they both evolved into Umbreons during it, and fell asleep. Sarah disappeared overnight. In the morning, Umbreon went home. When Jolteon2 saw his son, he did not know what to do, but to ground him. However, in Umbreon's room, the window was left open, and he made his way to the gym, disobeying his parents. As soon as Buizels found out, Pup was aqua jetted home. Since he had no idea why he was punished (He didn't even know that it was sex,), he asked Lady Leafeon. She was more linent with him, only allowing him to stay at home or the gym for a week

Aftermath

 * Pup evolved into Umbreon
 * Pup's personality changed, so he was more of an ass.
 * Sarah disappeared
 * Umbreon not allowed to be anywhere but gym and home for a week.
