Starlight arrived at the castle after playing in the snow with Rainbow Dash.

"Phew...that was fun." Starlight said. "I never knew a snowball fight could be so...fun..." She added.

"Yeah. And if you ask me, we both won." Rainbow Dash said, smiling.

"Huh?" Starlight was confused.

"It was good hanging out with you today. I'll admit, I've been nervous about this whole 'letting you hang with all of us' thing Twilight told you to do this winter, but I think I've gotten over it." Rainbow Dash said.

"Still hung up on all that past stuff huh? Look, I've apologized for it already. Like, seventy times over." Starlight said.

"More like seventy-five, but your right." Rainbow Dash said. "I think it's time for me to let bygones be bygones..." She said and put her hoof out. "Let's both be better friends from now on, deal?" Rainbow Dash said.

"Deal!" Starlight bumped hooves with Rainbow Dash before closing the door and hanging her snow gear up. She then went to find Twilight in the Map room.

"Oh Starlight!" Twilight said, smiling as she saw her student enter the map room. "Did you have fun with Rainbow Dash?" Twilight asked.

"Yes. A lot of fun, actually." Starlight said. "I can see why you hold your friends in such high regard. All whose left to hang with is Applejack and Pinkie Pie." She said. Twilight blinked.

"Wait...you've spent time with everyone else?" Twilight asked, unsure.

"Let me recap the past day and a half for you: I started by helping Fluttershy get her animals ready for winter hibernation, then I helped Rarity out with some designs she could give out to the people from that village I helped form, and I just got done with Rainbow Dash. I thought you might want to go last." Starlight said.

"Actually...I can't be last. Not for another couple of days." Twilight said.

"Why's that?" Starlight said.

"Applejack took off with her family so that they could spend Hearth's Warming eve with Pinkie's family." Twilight said.

"Oh. Well I guess I can spend time with you next. Why are the apples going to Pinkie's rock farm for Hearth's Warming anyways?" Starlight asked.

"Well back when the Golden Oak Library existed, I once did some genealogy research for each of my friends. For the most part, nothing surprised me." Twilight said.

"Genealogy? Isn't that basically familial study and research?" Starlight asked. Twilight nodded.

"Things got interesting when I started digging into both Pinkie Pie and Applejack. The more I dug up on one, the more I would find out about the other. Eventually, I found out that the two are cousins. Very distant cousins, but cousins none the less." Twilight said.

"Wait, so their related?!" Starlight exclaimed.

"Yep. Sure their just cousins, but ever since then, Pinkie Pie and Applejack have taken their friendship with one another to a whole another level." Twilight said.

"So this is them attempting to make some connections huh?" Starlight said. To which Twilight nodded. This gave Starlight an idea. "Hey Twilight, I think I'm going to do some Genealogy research of my own. I'll let you know if I find out anything interesting." She said. She then took out a locket and trotted off.

"I wonder who she could be related to. Well, I really hope it's nothing as crazy as Pinkie Pie. Then again, what could top that?" Twilight asked. Suddenly she felt a shiver down her spine. "...Why does it suddenly feel like I've just tempted fate?" Twilight Asked.

"Not even one percent..." Starlight said. She had just did testing to compare her DNA to that of her mothers, which she had a spare lock of mane of. "But that can't be right..." Starlight asked. She then decided to call her dad. "Hey dad it's me. Yes I'm still alive. No, I'm not bad anymore, honest. Listen dad, your still my dad right? Then did you cheat on my mom?" Starlight asked. "...What do you mean why do I ask? I just tested my DNA to that of my mom's and it's not even a one percent probility. In fact, it's zero. So I have to know, who is my mother?" Starlight asked. "...Why are you so instant I know who it is? Okay then, how can she be my mother if..." Starlight stopped her self. "...Nothing dad. Goodbye. Love you..." She said and hung up. "...I'm adopted..." Starlight said. She went to find her teacher right away.

"ADOPTED?!" Rainbow Dash exclaimed after Twilight told her, Fluttershy, and Rarity.

"It's the only explanation. My dad was very insistent that my mother was who she was. And if he's so certain that the mare I know as my mother is my mother, then that only can mean that I'm not the biological daughter of the two ponies I know as my parents." Starlight said.

"Well even if you are adopted, I think it was kind of those two ponies to raise you as if you were their own." Flutttershy said.

"You know something...your right." Starlight said with a smile. "It was nice of them. Still, it makes me wonder who my real parents are." Starlight said.

"I hope you find out who and tell us darling. I would love to make you a little necklace to celebrate." Rarity said.

"Of course you would..." Rainbow Dash said.

"Now Rainbow please be nice. This is already potentially life changing for me as it is." Starlight said. "Still, I'm hoping that no matter who my parents are, it changes nothing about out friendship." She said.

"It won't. No way am I about to let who you were born to effect how I feel about you." Rainbow Dash said. "It'll be your parents I'll be more pissed at." She added.

"Gee, that's a one eighty." Starlight said.

"Element of Loyalty, remember?" Rainbow Dash said with a smirk. "And your biological parents obviously weren't loyal to you." She pointed out.

"I'm sure they must have had SOME reason for it. Let's not rush to judgement now." Twilight said.

"Twilight's right. Maybe I was born into a family who already was struggling to get by; or had so many kids that they couldn't afford to raise another one; or they maybe they were just too young to legally keep me." Starlight said. "The explanation could literally be anything." She added. Everyone looked at her. "...What? Was it something I said?" Starlight asked.

"You know...for a moment there, you sounded just like Twilight." Spike said, speaking up for the first time.

"Yeah. It was so weird. And the way you went about saying it was totally something Twilight would do too." Rainbow Dash said.

"Not to mention just how many different very reasonable explanations you gave us just now. It's not unlike something Twilight would do." Fluttershy said.

"I think what we mean to say Starlight Darling...is that if we didn't know better, we'd swear you were Twilight's sister or something." Rarity said.

"What?! Me? The sister of my own Teacher?!" Starlight exclaimed. "That's a stretch if I've ever heard one!" She said and left the room.

"Girls please..." Twilight said. "I could just very easily be rubbing off on Starlight. Or any number of specific reasons. I'd list them all right now, in fact..." Twilight suddenly stopped herself and went wide eyed. "...Oh sweet Luna, please don't let that be the case..." She said. "Could my student...really be my sister?" Twilight asked.

"If she is, that's one Tartarus of a thing for Applejack to miss out on." Rainbow Dash said.

"Knowing Pinkie Pie, she'll probably throw a party over it..." Rarity mentioned.

"If nothing else, I'm sure everyone will support the two of you." Fluttershy said.

"Even if I'm secretly praying that Starlgiht is not my sister?" Twilight asked. Her friends nodded. "I was a afraid of that...I guess time will only tell though." Twilight said.
