"Finally! I thought we'd never get to Canterlot!" Twilight said, stepping off the train. The three other ponies piled off, and watched the train leave. Octavia suddenly sat up, and rubbed her eyes. "Hey! Hey! Twilight, it's Vinyl! She's over there! Hey, yo! Vinyl!"
She turned around, surprised to see all four ponies together. "What? You're kidding. Spitfire, Octavia, and you...uh..."
"Twilight." Twilight supplied.
"Yeah, yeah. What's going on?"
Trixie stepped forward. "We're going to banish-"
"-The dj at the party!" Spitfire cut in, "that's why we need you!"
Trixie shook her head, "a party? Actually-"
"-It's kind of more of a house-concert." Twilight interrupted.
Trixie was not happy. Twilight and her friends were holding something from her. "Twilight, what are you hiding from me?" Twilight looked shocked. "What?! I'm not hiding anything!" Derpy chimed in, "yeah, we're not hiding anything." Trixie fixed her eyes on Derpy, who, compared to Trixie, was smaller and less confident. Derpy tried to melt into her own shadow because of the look Trixie was giving her. "Don't get involved in things you don't understand, weirdo." Derpy buried his face in his hooves, and started crying.
"Hey, c'mon Trixie. That's not cool. Derpy's my friend," Twilight said.
Trixie huffed, "yeah, well, I'm not exactly enjoying your negativity toward me."
"But I didn't-"
"This mission is bound to fail. I refuse to be part of it."
Trixie turned her back, and Twilight let her. Twilight was gong to let her walk away too, but as Trixie took a few steps, her body began to turn grey, just like Rainbow Dash. Twilight shook her head, and tackled Trixie. She yelled in surprise as Twilight pinned her to the ground. Trixie struggled, but Twilight held her down. She began to use her healing spell, and ventured deep into Trixie's mind. She saw her true feelings: her loneliness, and her constant need for revenge against Twilight. Twilight began to feel weak, and a familiar laugh echoed around in her head,
"Now you've done it, Twilight! Give it up! Ha ha ha ha haaaaaaaaa!"
Twilight finished her spell, and pushed Trixie away, and the evil laughing faded away. Trixie was back to normal again, but she was cold, and shivering. Twilight turned around and said, "Spitfire! Find Big Macintosh! Look anywhere farm equipment is sold!" Spitfire nodded, and dashed off to find Applejack's older brother. When Twilight looked down again, Trixie was gone. Twilight looked around, and saw Trixie running away.
Twilight began to chase after her through the streets of Canterlot. She saw some guards standing on a plaza, where Trixie was heading, and yelled, "stop her!" The guards responded quickly, grabbing the poor mare as she flew by. They dragged her over to Twilight, who sadly said, "let her go. She won't run."
She didn't. Trixie just sat quietly for a long time. Finally, she said, "Twilight Sparkle, can you forgive me?" Twilight smiled. "Again? I think you need to be less deceiving, and more cunning!" She said, elbowing Trixie, who smiled back. Twilight helped her up, and said, "now c'mon! We've got some chaos-spirit-exorcising to do!"
