Prism and Glimmer

Prisim hid behind the couch, trying to be as quiet as possible.  Beside her was her sister, Glimmer.  She was in the same position, ready to pounce.  The five year old filly pushed her rainbow mane out of her eyes and focused on what was on the other side of the couch.  She spread out her wings and looked at her sister.  The two silently counted to three before jumping up and over.

Before they could reach their targets, they stopped in mid-air, held by a purple aura.  The two were brought in front of their parents who smiled at the two shocked fillys.  They both were brought to one of the parents.

"You know that we will be hard to sneek up on." said the lavender alicorn.  She was their mother, Twilight.  But this isn't the weirdest part.

"Besides, you still tend to giggle a lot when you're up to something.  This was said by a cyan earth pony with a rainbow mane.  Her cutie mark was of a rainbow lightening bolt that came from a cloud, a cutie mark found on pegasi.  The twins never got why an earth pony had a pegasi cutie mark.  This was their other mother, Rainbow Dash.  Yet another pegasi name.

"Why do you guys have to be so hard to surprise?" asked Glimmer.  The white unicorn filly crossed her hooves, her purple mane fell over her blue eyes.  Twilight set Glimmer next to her, Prisim by Rainbow.

"We just are, I guess.  A lot has happened to us over the last ten years and your mother and I have learned to expect things."  She nuzzled Glimmer.  "But there has always been suprises.  You two, in some sense, were a surprise."  Glimmer smiled and nuzzled against her mother, Prisim doing the same to Dash.  Twilight looked at the clock and sighed.

"Rainbow, do you mind heading down to the school and getting these two registered?  Celestia, Luna, and I have court in an hour.  Some issue that needed all of our attention."  Twilight sighed, lifting up Glimmer and moving her so she could stand.  "I'm going to go take a shower and get dressed."  Rainbow stood up and gave Twilight a quick kiss.

"Alright, don't take too long.  The girls are coming over sometime today."  Twilight nodded and walked into the bathroom.  Rainbow motioned for the two fillies to follow her.

"Mommy, why do we have to go to school?"  Rainbow snorted.

"Because, you can get smart and be cool like your mother.  Well, she had some better luck, but going to school gives you a chance to meet friends, earn your cutie mark, and learn awesome things."  She frowned and looked over at them.  "Now, I know school won't start for a few more weeks, but I want you to keep in mind that while you are there you must pay complete attention."

"Why?" asked Prisim.

"I don't want you to be like me.  I want you to be smart, intelligent mares some day.  Especially you." she said, looking at Prisim.

"Me?" asked Prisim, not sure why her mother focused on her.

"Yes, you.  If you're anything like me you will end up getting cocky and brash and will drop out.  Now, this will not happen, right?"  Glimmer stepped forward.

"Mommy, we haven't even started school yet."  Rainbow Dash rubbed the back of her head.

"Yeah, well, I worry.  That's all."

"Rainbow Dash?  Worry?  I would never think that possible."  Rainbow turned to see an alabaster unicorn with a dark purple mane.  She was followed by a orange earth pony, an energetic pink pony, and a timid yellow Pegasus.  Rainbow's eyes lit up as she saw the four.

"Well, Rarity, I tend to surprise.  Its good to see you guys again.  With Twilight's duties and these two." she said, motioning at the two fillies you were behind her.  "We tend to get busy."  The orange earth pony walked over to her and put a hoof on her shoulder.

"It still wouldn't hurt y'all ta send a letter to us sometimes."  Rainbow blushed and scratched the back of her head.

"Yeah.  Sorry, but you guys might have to wait a bit.  Twilight has an important meeting to attend to and I need to get these two registered at one of Canterlot's elementary schools.  There is one near the castle so I might put them there."

"Oh I here the education here is just wonderful!  You just have to watch out for the children of all the sno-" Rarity was cut off by Applejack glaring at her.  Rainbow sighed.

"Yeah.  But these two will get through it, no sweat.  Right?" she asked, looking down at her daughters.  The two fillies smiled at their mother and nodded.  Rainbow ruffled their manes.  Rarity looked at Glimmer before turning back to Rainbow.

"Rainbow, I always meant to ask, but why does Glimmer have a solid mane colour unlike you and Twi?  I didn't know either of you had solid mane colour in your family."

"That's my mom's side of the family.  While my dad had rainbow, mom had solid blue.  I contributed on the pegasi and mane colour, Twilight the unicorn and cleverness."  Rainbow looked out the window outside at the sun.  It was almost at its zenith and registration closed at two.  "Well girls, there are rooms prepared for you.  Go back to our room and ask one of the gaurds to bring you to them.  Make sure to tell them I sent you.  They can be really strict."  With that, Rainbow took the two fillies down the hall.

__________________________________________________________________

Rainbow held the take-home paperwork in her mouth.  The two fillies layed down on her back, slowing her down a bit.  She smiled at the two's enthusiasm at seeing their school and classroom.  They were soon tired and now fast asleep.

She nudged open the door to the small living room in her and her family's quarters.  Twilight and the others were sitting down and talking as she walked in.  Twilight stood up and helped her tuck in the twins before joining the others.

"The twins were a lot of work, I take it?" said Twilight as Rainbow sat down, groaning as she did.

"They weren't much trouble, but I think they threw out my back."  Applejack gave a small laugh for she knew how that felt like.

"Well, now we got a few other things about."  Rainbow sighed and looked back at the twin's room.

"Like we don't worry about them, enough."
