Chapter 1- Scream of Surprise

It was just a normal day in Nimbasa City when White heard the voice. She and Black were at the amusement park, having fun on the rides and training. Elesa was on vacation, so everywhere in the amusement park was open to guests to ride, even the roller coaster in her gym. That's where White was, riding the rails to her heart's content. Black was sitting next to her in the first car, his hands in the air and yelling loudly. They felt the air rush past them as the car sped up and accelerated toward the loop. This was always White's favorite part; she loved the feeling of being suspended upside down for that split second, dangling helplessly from the car.
"Woo!" She screamed as she felt herself being pulled downward by the loop's gravity.
"Yeahhh!" was Black's reply as they descended the rest of the loop. The car rounded the last curve and slowly decelerated to a stop.
"Again?" Black asked.
"Again!" White agreed. They remained seated in the car and waited for the ride to start up again. They were definitely doing more roller coaster riding than training, for this marked their sixth ride in a row. The ride started again, and White could feel the excitement surge through her as they sped toward the first curve. They were jerked to the side of the car as they rounded the curve and headed to the first loop, their favorite part.
"Woo!" White screamed.
"Yeahhh!" Black yelled.
"Whoaaa!"
White whirled around to find the direction of where this scream came from, but she could find no one else making that loud of a noise. "Strange," she thought out loud. "I wonder where that came from."
"You say something?" Black shouted at her.
"No," she shouted back. The car twisted around another bend and approached the last loop. "Woo!" she screamed.
"Yeahhh!" Black yelled.
"Whoaaa!"
White heard the scream again. It was very high-pitched, like that of a little girl, bit it didn't seem to be coming from any particular direction. Bewilderment was written all over White's face as the roller coaster slowed to a halt.
"You okay, White?" Black asked, noticing her expression.
"Umm, y-yeah," White stammered shakily. "Can we n-not g-go on the r-roller c-coaster again?"
"Alright," Black said, now seemingly oblivious to her unease. "We gotta catch up on our training anyway. Let's go."

Black and White surveyed the amusement park until they found an open space suitable for battling. It was a grassy plain littered with sparse groups of trees. Black and White spaced themselves apart and each clutched a Poke Ball in one hand.
"Ready, White?" Black asked.
"Bring it on!" White answered, her confidence having returned. "Servine, come on out!" Servine appeared in front of White and stretched its body out.
"Go, Pignite!" Black called. Pignite came out of its Poke Ball, flexing its arms. "You go first," Black offered.
"Alright. Servine, use Leech Seed!" White ordered. A seed sprouted from Servine's tail as it quickly slithered up to Pignite.
"Dodge it!" Black commanded. Pignite did its best to try to avoid Servine, but the agile grass snake was too quick for the bulky fire pig. Servine got in range and flicked its tail, sending the Leech Seed at Pignite. The seed sprouted vines that wrapped around Pignite, glowing red every so often to sap the Pokémon's energy.
"Nice move."
"Who said that?" White asked.
"Said what?" Black responded, tilting his head to the side.
"Oh, um, nothing," White said, more and more perplexed.
"Ok, then. Pignite, Flame Charge!" Black shouted. Pignite stamped its feet on the ground, creating a thick cloud of dust. It released a plume of flames, shrouding itself in the enflamed dust. Engulfed in the fire, it charged at Servine. White, still mulling over this weird voice, failed to notice this until Pignite was only a few yards away.
"Servine, dodge!" She yelled shrilly. Servine slithered away as quickly as it could, but was a second too late, and it was struck in the tail by the flaming Pignite. Servine hissed in agony at the burning impact.
"Pay attention, you idiot."
White was now on the verge of insanity from this eerie voice.
"Umm, White?" Black asked, finally noticing her unease. "You sure you're good? You seem really...off today."
"Yeah," White answered. "I guess I am."
"Pignite, return!" The Pokémon was sent back to its Poke Ball. "It's getting a bit late anyway, you should just head to sleep." Black advised.
"Alright, I guess I will." White agreed. "Servine, return!" Servine returned to its Poke Ball as well. "Good night!" She turned and headed to the Pokémon Center where she and Black were staying while in Nimbasa.

White entered her room at the Pokémon Center and flopped on the bed out of exhaustion. Not physical exhaustion, but of mental exhaustion from trying to decipher the source of the voice. Who was talking to her? How was she talking to her? Why was she talking to her? All questions without answers.
"Damn it! Whoever you are, why are you doing this to me?" She screamed in her mind.
"Calm down, I'm not going to hurt you."
"Who said that?" White asked cautiously.
"Teeheehee, I did."
"And you are?" White was getting more and more intrigued by the voice.
"My name is Darcia," the girl finally introduced herself.
"Okay, Darcia, why the hell are you in my head?" White snapped.
"Teehee!" Darcia giggled cutely. "Because I can telepathically talk to people! And it's fun!"
"Why me?" White persisted.
"Because I'm booored," Darcia whined, hedging the question. "Will you come play with me?"
"Um, no, sorry, but I need to get some rest," White said, annoyed. "But seriously, why are you doing this to me?"
"Maybe I'll tell you if you come play with me!" Darcia bribed.
"Oh, fine," White gave in. She hoped that playing with this stupid little girl could clear her mind since she didn't have to worry about where the voice was coming from. Then she realized something. "Wait a minute, how will I find you?"
"That's okay," Darcia assured. "I'll come get you!"
"Wait...WHAT?" White yelled. She didn't bother waiting for an answer. She immediately dashed to the door and locked it, then did the same with the window. She thought she was safe and calmed down quite a bit. Then she heard the knock on the window. "Wh-who's th-there?"
"Teehee! I told you I'd find you!"
White screamed a shrill scream of pure surprise. Then she blacked out.
