"We are welcoming back the best-est ponies on our show today, every creature," Pinkie was bursting with excitement, "I have asked them to join us from my rock farm and have agreed to join us again today!"
"I didn't!" Limestone grumbled.
"You said yes in my head, so that's good enough for me," Pinkie smiled, "So please welcome my other sisters, other than Marble here," She rubbed Marble's cheeks together, who blushed, "Limestone and Marble Pie!" The other creatures clapped together. Limestone just huffed and sunk into her seat.
"It's a pleasure to be here, Pinkie," Maud said in her usual monotone voice, "I particularly like the special mixture in the bricks and cement to aid in the studio's acoustics."
"Thanks, I guess," Gabby gave a strained smile, "You should compliment Octavia and Vinyl for allowing us to borrow their studio. Maybe you should tell them."
"I will keep that in mind," Maud simply answered back.
"How are you related to them?" Silverstream asked. This caused all the Pie sisters to look at each other, then back to Silverstream. Limestone took it hard.
"You've got a problem with that?" Limestone growled, causing Silverstream to recoil back.
"N-no, it's just that Pinkie is the most excited one of the group," Silverstream tried to defuse the tension.
"Gaze into the eyes of Limestone Pie, you pink chicken-horse. Cross me and my family, and I will crush into with enough pressure, that you will become nothing more than-" Pinkie quickly cut in.
"Okay Limestone, I think Silverstream got the message," Pinkie pushed Limestone back, Silverstream nodding quickly in understanding, sweat dripping down her face.
"We may all be different, but we are family nonetheless. It doesn't matter if we are different. Family isn't just a name or heritage, it's all about looking out for each other. Like how sandstone comes in many layers, we are layers under one family," Maud explained simply. Every creature turned to Maud with stunned faces, Limestone and Marble included. Pinkie wiped a tear from her eye.
"That was beautiful Maud," Pinkie smiled warmly, "You can put that as your next poem somewhere."
"I will call it, The Family Foundation Stone," Maud simply described.
"She can also do stand-up comedy," Pinkie excitedly told the others. They looked to Pinkie, then back to Maud, then back to Pinkie. Just accepting that it was Pinkie Pie, they simply gave small strained smiles and nodded quietly.
"What do you call a pony without a horn or wings?" Maud gave an example.
Dead silence...
"Earth Pony." At that Pinkie burst out laughing. The others were clueless at the punchline. Limestone just rolled her eyes whilst. Marble gave a blush as she silently chuckled.
"Yeah," Autumn slowly with semi-sarcasm said, "I can see how they are related."
"And can you believe that we might me also related to Applejack's family as well?! Think of all the apples and pies!" Pinkie then went into another sugary fantasy, "Creamy, creamy apples and pies, with a fresh pouring of custard on the side."
"Pinkie!" Limestone huffed, "Focus!"
"What? Oh, sorry!" So yeah, "Think about having a double large family! We've had two Hearth's Warming's now. Though the first one went a bit haywire, We had the our family come over to Sweet Apple Acres for their Hearth's Warming and share their traditions!" At the memory Marble winced slightly.
"What's wrong?" Gabby asked Marble, who blushed a bright red.
"She's just sad that she saw her crush and marefriend kiss under the mistletoe," Pinkie giggled.
"Ouch," Autumn winced.
"But don't worry," Pinkie comforted her sister, "There are plenty of diamonds in the cavern, you too Marble." Limestone facehoofed.
"Not this again," Limestone huffed.
"I think we will take a place there to save Limestone from embarrassment. Thank you, Pinkie, for inviting you're sisters back to talk about family more," Silverstream chuckled nervously.
"Thank you!" Limestone huffed, "Maud promised to show me her Ponyville-adjacent living area."
"You will like it," Maud smiled.
"Did Maud actually smile?" Gabby gasped.
"I smile all the time," Maud answered plainly.
Every creature laughed.
