It was Friday afternoon. Most of the Rainbooms were standing by what remained of the Wondercolt statue. The school day had just ended and they were all looking forward to celebrating Pinkie's birthday on Saturday. In fact, Pinkie was the only member of the band not present.
"Aaaaaaaaay-Jaaaaaaaaayyyy!" Pinkie Pie yelled from across the front lawn if the school, her pink hair flowing behind her like a pastel flame.
"What is it Sugarcube?" Applejack asked once Pinkie had reached the group and caught her breath.
"I need your help, I haven't gotten Marble a present yet, could you drive me to the store?" Pinkie Pie asked still slightly out of breath.
"You haven't gotten her one yet? She's your twin sister for sweet Apple's sake. Apple Bloom and I picked up her gift last week." Applejack said.
"Who is Marble," Rainbow Dash asked, "and since when does Pinkie have a twin sister?"
"I have more than one sister. You've all met Maude, she is the oldest. The there is Limestone, she is a senior at Crystal Prep, then Marble and me." Pinkie explained then pointed, " here comes Marble now."
The girls looked where Pinkie was pointing and saw Apple Bloom walking with a girl who looked to be Pinkie's age only she looked nothing like her sister. Where Pinkie had pink skin and hair, her sister had light gray skin and dark gray hair with lighter gray highlights running through it. She noticeably blushed as she and Apple Bloom approached the group.
"Hey AJ, Uncle Iggy and Auntie Cloudy are going to let me spend the night at their house tonight." Apple Bloom said to her big sister.
"O.K. Sugarcube, just remember to follow their rules." Applejack replied.
"Hiya, I'm Rainbow Dash." Rainbow said, holding her hand out to Pinkie's sister. Marble blushed again and tried to hide behind Pinkie.
"What's wrong darling?" Rarity asked. Marble just blushed some more and let out a squeak.
"It's ok Sugarcube, you're fine." AJ said putting her hand on Marble's shoulder for comfort, "Apple Bloom, why don't you and Marble head on over to the Pie's house, we'll see y'all tomorrow."
Pinkie waited until Apple Bloom and Marble were out of earshot then turned to her friends. "I probably should have told you that new people make her nervous."
"She seems to get along with Apple Bloom." Sunset observed.
"When Apple Bloom was a new born, Marble was just fascinated by her." AJ said.
"So AJ can you help me find a gift for Marble?" Pinkie asked using her best puppy dog face.
"As shucks, that's part of being family, of course I'll help you cuz." AJ said before looking at the others. "Meet up at the cafe in an hour?" All the girls nodded in agreement.
==================================
With AJ's help Pinkie had found a 180 piece art set and a new sketch book for her sister. The cover of the sketch book was actually a picture frame and Pinkie had decided to put a picture of all four Pie Sisters in it.
"She'll love it Sugarcube." AJ said when Pinkie showed her the gift. Pinkie thought that the gift was perfect.
"I wonder what kind of cake our parents got us this year, I love chocolate, but Marble prefers angel food cake." Pinkie said as they walked out of the store toward AJ's pick-up.
"Maybe they got one of each." AJ said as she unlocked the truck, "Remember last year when Limestone over slept through her own party?"
"Yeah, she wasn't happy when Gummy and Apple Bloom woke her up." Pinkie Pie said with a laugh at the memory.
After arriving at the cafe, AJ and Pinkie found their friends already inside at their normal table. In front of the seat the Pinkie normally sat in was a Jumbo Super Sundae Surprise.
"Happy birthday Pinkie!" her co-workers said as they walked in. Pinkie couldn't help but smile. As Pinkie sat down she saw that her friends all had questions that they wanted to ask.
"Marble is older than me by five minutes." she said.
"Where were your sisters during the sleep overs we've had at your house?" Rarity asked.
"Marble normally hides in her room and Lime usually stays with her friends." Pinkie answered.
"Ah usually go and spend some time with Marble during each sleep over." AJ said.
"So that explains why you disappear." Rainbow said.
"Um, Marble seems really nice. I think I have chemistry class with her." Fluttershy said quietly, "I didn't know she was your sister though."
"Now that I think of it, I think she is in my art class." Sunset said thoughtfully.
Pinkie nodded. She loved her family more than anything else in the world, and she was glad that she could share her family with her friends who she also thought of as family.
"I'll ask her if she wants to join us for our sleep over tomorrow night, if she does we need to take it slow." Pinkie said eyeing Rainbow Dash.
"I understand." Rainbow said. Before taking a bite of her bacon cheese burger.
"Ah hope you do Rainbow,"AJ said, "Marble is my cousin, and if you step out of line you'll answer to me and Lime."
"Now there's a match-up I would love to watch." Pinkie said, which caused AJ to chuckle.
"What's so funny?" Twilight asked.
"Limestone tends to get, uh, over-zealous, where her family is concerned." AJ said, "she almost broke Big Mac's arm once when she thought he was playin' to rough with Pinkie and I when were Apple Bloom's age."
I remember that,"Pinkie said, "Big Mac couldn't feel his arm for a week!"
"Oh, my!" Fluttershy exclaimed.
That had brought a giggle from all the girls.
==================================
Pinkie Pie was uncharacteristically quiet during the drive back it her house and that had Applejack concerned.
"Whatcha thinkin' about Sugarcube?" AJ asked trying not to let her concern bleed into her words.
"Nothing much, just my little sister." Pinkie answered.
