Argyle kept the front door open just a crack so he can listen in as he just shook his head with a smile before he closes it, causing a framed photograph on the wall nearby to tilt askew himself giving Sunny a ride on his back with Aurora beside them with bright smiles. Nudging it level, he finds his daughters slumping glumly at the kitchen counter and regarding their Rainbow and Rarity figurines. The icing around their mouth has been cleaned away. She voices a barely audible sigh as Aurora nudged gently at the Fluttershy figurine as he crossed to them.

"What's the matter, Sunny-Bunny, Rory?" Argyle asked them curiously.

"Hitch and Sprout still don't believe me and Sunny, Daddy." Aurora said glumly.

"Maybe one day they will. But the important thing is that you both stand up for what you believe in. Okay?" Argyle told them as Sunny perked up at that.

"Well, when I grow up, I'm going to show everypony that we're right." Sunny said brightly.

"Oh?" Argyle became intrigued.

"Yeah! And someday, the both of us will meet unicorns, or a pegasus, and we'll be best friends forever." Sunny said as she bounced happily at the thought of having all three pony kinds in harmony.

"Well, maybe today's that day." Argyle said before he glanced at the window.

"Look! A unicorn!" He pointed which made Sunny and Aurora gasp in delight.

The two raced over to the window as he ducked out of view.

"Where? Where?" Both Aurora and Sunny looked outside.

"Over here!" Argyle said playfully as they both turned to him and giggled.

Back to him, now proudly wearing a cardboard horn smack in the center of his forehead and a cocked-eyebrow smile. It slides down to his nose, prompting laughter from them and he slips it back into place and lets them climb onto his back for a gallop around the kitchen.

"Whee! We're soaring through the sky!" Sunny cheered before Aurora had an idea.

"Wait, Dad! I have an idea!" She said as he looks at them both.

He stops to lend an ear to hear their idea. Tilt up through the ceiling and stop at the room in which the three foals were playing now recognizable as the chamber that contains the lighthouse's lantern. Sunny is at the central table, hard at work drawing something with Aurora making a lantern as Argyle looks on. Through the expansive windows, the sky darkens into the evening.

Sunny presents the drawing to their father who looked at it.

"'Dear unicorns and pegasi: You have friends in Maretime Bay. Come visit us.'" Argyle reads.

"Can we send it?" Sunny asked as Argyle nodded with a smile.

Written on the sheet in her hooves: a crayon picture of one pony from each of the three tribes, enjoying treats from a picnic basket against a rainbow/cloud/star backdrop. The message is written in, with "you" misspelled as "yu" and the I in "pegasi" jogged up above a crossed-out U. There is no punctuation except for an exclamation point after the last word.

"I think it's our duty." Argyle said with a chuckle.

They attached the note to a paper lantern that is slowly rising from a balcony outside the lantern room, buoyed by the thermal air currents generated from the lit candle inside. Tilt up to follow it past father and daughters and over the railing into the night air beyond as they watched it float away. The candle flame reflects in Sunny's wide, enraptured eyes as the craft sets off on a journey to parts unknown. Noticing that he is still wearing the fake horn, Argyle pulls it free and parks it on Aurora's forehead she giggles with Sunny and both nuzzles his foreleg affectionately.

"Can you tell us the story?" Aurora asked him as he chuckles in amusement. He forgot how many times he told his daughters about the story.

"Again?" Argyle asked fondly.

"Pleeeease?" Sunny said with a cute smile. Argyle couldn't help but smile. Might as well tell them the story again since it was their favorite.

"Once upon a time, many, many moons ago in ancient Equestria, there lived a very special-" Argyle began but Sunny interrupted.

"Unicorn!" She cheered.

"The unicorn was very bright." Argyle continues with a chuckle.

They were now in the bedroom as Argyle was tucking the two fillies into bed.

"As bright as the sun." Aurora added.

Now in their bedroom; she sits up in bed and is playing with her Twilight toy, while he reads from his journal at her bedside with Aurora sitting beside her. The wall above their headboard is festooned with crayon drawings, and a stuffed doll is tucked in next to her. They have shed their cardboard wings and horn, and the lighting is dim.

"One day, the Princess summoned her to the castle for an important assignment." Argyle read to them.

"To learn about friendship!" Aurora and Sunny both said.

"Mmm-hmm." Argyle nodded.

He takes the figurine from her, close-up of her nightstand, holding the other five, as he sets it in line with them.

"She soon made lots of new friends." Argyle said as Sunny smiled happily.

"Earth ponies, pegasuses, and unicorns." Sunny said as Aurora giggled.

"Pegasi, Sunny." Aurora said which Sunny giggled at her.

"Together, they showed everypony the magic of friendship, and how to live in harmony." Argyle finished as he lifted up the lamp he was working on for them to see.

"Wow... you finished it!" Sunny breathes in awe.

"Pretty neat, huh?" Argyle smiled as he set it down on the shelf with the toys and wind it up.

A light inside glows as the framework begins to rotate, images of ponies appear on the walls/ceiling and begin to move within a scatter of stars as the frame slowly rotates and the fillies voices a quiet gasp. Cut briefly to the upper reaches of the light show as he finishes, then back to Sunny.

"Earth ponies watched in wonder as pegasi painted rainbows across the sky. The nights were lit up by a hundred unicorn horns." Argyle said as both Sunny and Aurora watched in awe.

"It's beautiful." Sunny voiced as Argyle chuckled.

She and Aurora settle drowsily onto her pillow.

"I wish I had a friend who could fly around or float things." Sunny hoped as she let a yawn.

"Why can't we be friends anymore?" Aurora asked sadly as she rubs her eyes sleepily.

"That, my fillies, is a big question." Argyle sighed as he tucked them both in.

"And maybe one day, we'll figure it out, together. We'll do our part..." Argyle said as both Sunny and Aurora out their hooves on his.

"...hoof to heart." They said.

Placing a gentle kiss on the bridge of his daughters' nose, he turns for the door..

"Good night, Daddy." Sunny said as Aurora snuggled close to her.

"Night-night, Daddy." Aurora yawned.

"Good night, my little ponies." Argyle bid them good night before closing the door behind him.

Sunny turned sleepily to the mane six figurines with a blissful smile.

"Good night, friends." She whispered before they both fell asleep.

The room is filled with various playthings and appropriately disorganized for fillies their age. Argyle has left the journal lying on their bed shared as the two drift off to sleep.
