Why...sister?

"Well, it turned out that Luna is failing magic school," Tia wrote in her journal and then continued, " She always says it is because she can't process the material, or she can't focus on flight school and magic school at the same time, or the teacher is an idiot who can't even explain that 2+2=4. I know why she is failing though, every little colt and filly in her class has their cutie marks, while her flank is still the same color of royal blue it was. She doesn't know I know, but I can tell, although I had finally gotten my cutie mark when my mom let me rise the sun for the first time, I could tell she was jealous, because she was being distant as I'll get out, which is never a good sign because she is always clingy. Maybe dad needs to take her out for lessons like mom did for me. Then maybe, if she does or even doesn't get her cutie mark, I'll take her to CloudsDale to tour the Rainbow Factory. It is the least I could do, to boost her self esteem. I'll talk to dad at dinner tonight, Luna is at a friend's house so she won't know. Maybe we can help her, maybe, just... maybe." She then signed it with the insignia of C in a fancy way. She put down her quill and walked out into the dinner hall, where her mother and father sat, eating the most gracious plates of hay and apples. She sat down at the table, thinking of the way to ask her father to help Luna. She finally broke the awkward silence that was in the air. "Dad? I have a question, about Luna." She asked unsuringly.

"Okay, shoot." He answered back

"Well, I know why Luna is failing magic school, it is because of her blank flank, per say. I think that you should help her, like mom did for me. Maybe she just needs support and confidence, and maybe, if I'm the one who rises the sun, just as mom, then maybe she Is the one who rises the moon, just as you, dad."

"Celestia, that is a very good observation, and you know what, when Luna gets back, I'll check into it."

"Really dad?! Wow, if she gets her cutie mark she will be really happy. I can see it now, her beautiful cutie mark, grazing the beginning and end of her flank. She will look absolutely gorgeous."

"I'm glad I have you kids, you keep me happy, and make me feel young."

"Oh daddy."

Tia was writing in her journal again, the night before Luna returned from her little friend. "Today is the day daddy said he would look into helping out Luna, it is after midnight, that is why I say today,but I can't sleep, it is to exciting and thrilling that Lulu may get her cutie mark. I can't help but think this will come back to bite me in the future, but heck, i don't care. As long as she is happy, that is all that matters." She signed it with her insignia again, put her quill down and tried to go to bed, but it was just so exciting, Lulu might get her cutie mark, it is just amazing, absoloutly amazing. She closed her eyes, hoping they would soon drift to slumber,  then they finally did.

"Daddy, you gonna help me try and find my true destiny?" Luna asked quizzically

"Precisely. Now try your hardest, and raise this model of the moon, if you can do it, then you can try very hard to raise the moon."

"Okay." Luna positioned her hooves to the perfect footing point. She tried her damnedest to raise the model, which to her felt the actual size of the moon. She had raised it high, higher than the model of the sun next to it. She had done it.

"Daddy! I did it!" She squealed

"I had the utmost faith in you my darling," he pulled her in to a hug, then continued at a whisper, "do you want to try the real one next?"

"Yes." She stepped to the hilltop, began concentrating, very much so. Her little wings arose her from the ground. Her horn began growing with the power of magic making it feel like a cenderblock on top of her head,she pushed through, breaking the barriers of levitation then she opened her eyes, releasing the moon into the night sky. Her father watched in awe as the moon arose before him, without the use of his magic. Luna rose to the ground, lying down on the ground with her flank glowing. Her father raced to is tired daughter, seeing her beautiful cutie mark appear before his very eyes. He yelled for Tia and his wife to come quick. They raced out seeing a mangled and tired body lying on the ground. They looked it over, seeing her new cutie mark. They both squealed in delight. Then they woke Luna up. "Lulu, wake up!" Tia said

"Huh?" She answered. Then she continued "Did I get my cutie mark?" She asked excitedly smiling brightly

"Yes. Its a beautiful crescent moon with black night and white stars around it."

'Awesome. So I raised the moon?"

"Mhm."

"Great, can I go to sleep now?"

"Yes." Tia picked up her limp, sleeping body, and carried her to their room, and tucked her in, and kissed her forehead. Then walked out and closed the door.
