Chapter One

"Your first friendship lesson is going to be… reuniting with Sunburst!"

"Greeeaaat."

Spike watched as Starlight started looking more worry about her first friendship lesson. 'Hmm, I wish I could help Starlight with her worries about her first lesson,' he thought, sighing.

Then a light bulb went off in his head and his face lit up, 'Wait! Who says she has to be the only one doing a friendship lesson in the Crystal Empire? If I remember correctly, all the princesses will be there, including Princess Celestia and I do believe a reunion is long overdue. And her last couple of letters did say she is feels like she is ready.'

Spike smiled a big grin, happy to have thought of an amazing plan, but then he remembered, 'Oh, right! There was that other thing she wrote in her letters. I better send out some notices, to prevent a panic.'

He ran off to a secluded part of the castle, picked up a book with a shimmering sun on the front, opened it up and started writing

2 hours later

"Is everypony ready to go?" Twilight asked, looking at her friends gathered around the cutie map. They all nodded at once.

"Absolutely, darling," Rarity confirmed

"Hey, Twilight," said Spike, as he walked into the throne room

"Spike! Where have you been? Are you ready to go to the Crystal Empire?" asked Twilight

"Well, um, err," Spike stammered, giving the door way a quick, nervous look, before sighing and explaining, "Well, I notice that Starlight was looking a little nervous about her first friendship lesson, so I might have invited somepony to come with us. So, Starlight won't be the only pony doing a friendship lesson."

"Really? Okay. I wish you had told me before hoof, but if you think it will help, then more the merrier," Twilight said, smiling down at her assistant. "Being them in."

"Before I do, I better tell you that, though she is technically a pony, she's decided to come as a non-pony," Spike nervous said, sweating a little

"A non-pony that is technically a pony? What are you talking about, Spike?" Rainbow Dash asked, looking at Twilight to see if she knew, but Twilight, seeing Rainbow's look, just shrugged.

"It's probably better if you see for yourself, all I can say is that thank Celestia, you told Starlight about the mirror portal," Spike said, turning to the door way, "You can come in now."

"Mirror portal?" Twilight asked with a confused look, followed by a sudden look of realization, "Wait! You mean…"

"Hey, Twilight," said a female voice

All the ponies looked towards the door, to see what looked like an almost hairless yeti, about as tall as Celestia, with a red and gold mane, yellow/orange skin and cyan coloured eyes. She was wearing blue pants, a light blue shirt with an attached see-through light-yellow shirt, a black leather jacket with orange chevrons on the sleeves, and boots to match the jacket. She had a shoulder bag with a shimmering sun on the front over her shoulder and what looked like a crystal necklace

"Sunset Shimmer?" Twilight asked, not believing what she was seeing in front of her.

"Sunset Shimmer!" All the other ponies exclaimed

"Heh, Hi," Sunset said sheepishly, "Sorry about the whole human thing. It's just that, I've been the other world for so long, I kinda prefer being human instead of pony. That, and I promised my friends I would find out what the size difference between ponies and humans is."

Twilight shook her head, to clear her thoughts, and looked at Spike, who also looked sheepish, "So, this is what you meant be non-pony and mirror portal."

"Yep," Spike replayed, "And don't worry about anypony panicking, I already sent out notices, basically explaining what Sunset just said, without mentioning the mirror."

"Well, I supposed that's okay," Twilight said, looking back up at Sunset, "I guess I should introduced you to everypony, though you sort of know most of them, or at least their human counterparts." She then introduced her friends and student to Sunset

"So, this is what a 'hooman' looks like?" Applejack asked, looking at Sunset

"Yep, and it's pronounced 'human'," Sunset replied

"So, what friendship lesson are you doing at the Crystal Empire?" Starlight asked

"I'm going to apologized to Princess Celestia," Sunset said, looking down with guilt, "For being a horrible student."

"Well, if you're ready to go, Sunset, I suggest we start heading to the station," Twilight suggested, heading towards the door.

"Yeah! Let's go!" Pinkie Pie yelled.
