(Typical. Asking when your Pokemon will evolve, then BAM! Evolution! xD)
Rusty and his Pokemon stopped hugging each other, and Rusty couldn't help but smile at Nikki. "I'm so proud of you, Nikki." He said, wiping tears from his face. Nikki cheered back. "Pika pi!" Then, Bolt started growling at something. "What is it, Bolt?" Rusty asked. Then, something was heard rustling in the bushes. Rusty got up, and started pushing his Pokemon back, protecting them, while unknowingly, leaving a pokeball on the ground that fell out of his pocket. When it appeared, he just looked at it.
It was a wild Eevee. Nobody moved for a good 10 seconds. The Eevee crept forward, and looked up at Rusty. "Eev?" It looked curious, then it smiled. Bolt stopped growling, and smiled back. Luna and Nikki were still confused. The Eevee made its way up to Rusty, and brushed up against his leg. Rusty smiled back at it. He then crouched down, and reached his hand out to pet it. Upon contact, the Eevee did nothing, besides let him pet it. The Eevee purred with pleasure. "Eevee!"
It then noticed the pokeball on the ground, and it walked over to it. The Eevee rolled the pokeball over to Rusty, and looked up at him, smiling. Rusty picked up the pokeball, and looked back down at the Eevee. "Y-You want me to..." Rusty stuttered, and the Eevee nodded. "Eevee!" The Eevee got ready to jump, as Rusty threw it gently in the air. The Eevee jumped up, and hit the pokeball with its front paws. The Eevee shape faded into a red glow, and it made its way into the pokeball. Then, SNAP! The pokeball closed shut.
When it landed on the ground, it started to shake, and wobble. After its third shake, it stopped, and the white circle (button?), turned red, turned back to white. "D...Did I...?" Rusty picks up the pokeball, and looks at it. He smiles. "I...I did." He held it tighter, grinning greatly. "I caught a Pokemon for the first time!" Rusty's Pokemon cheered for his successful capture of a new Pokemon, and a new friend. Eevee.
