Starlight followed Twilight Sparkle, Shining Armor, and Princess Cadence to the house where the parents of Twilight Sparkle and Shining armor lived.

Starlight gulped. One correction: The parents of Twilight Sparkle, Shining Armor, and Starlight Glimmer.

"Is it...normal for me to be nervous about meeting my biological parents?" Starlight asked.

"I suppose I would be too in your hoofprints, Starlight." Twilight said.

"But no matter what, I want an explanation." Shining Armor said. He knocked on the door.

"No turning back." Cadence said.

"Right..." Starlight said. Twilight Velvet and Night Light answered the door.

"Oh! Twilight and Shining...what brings you to Canterlot?" Twilight Velvet said.

"I do." Starlight said. "...Hello mother and father..." Starlight said.

"St-starlight?!" Night Light said.

"WAIT YOU KNEW?!" Twilight asked.

"We...may need to tell you what happened..." Twilight Velvet said.

"So Starlight before we tell you why we had to put you up for adoption...we need to know how this all came about." Twilight Velvet said.

"It's not that long of a story, actually..." Starlight said. "I asked Twilight about why one of her friends and the family they had were visiting another family for hearth's warming. Something about the two friends being cousins or something. Anyways, it got me into wanting to map out my own family tree, see if there's any distant relatives I might not know of that I would love to connect with. So I ran my DNA against my adopted mother's." Starlight explained. "The test came back with a zero percent chance of relation so I called my adopted father and he was so sure about never cheating on his wife that it just clicked for me that I had to be adopted." She continued.

"You didn't call your adoptive mother instead?" Night Light asked. "She's the one that was there for the paper work to adopt you before you were even born." He added.

"...We'll get back to that statement. To answer your question, I couldn't talk to my adopted mother about it because she was killed in a bug bear attack when I was ten." Starlight said.

"Oh how horrible! Your adopted mother was such a nice mare; she did not deserve to be killed by such a beast!" Twilight Velvet said.

"...Yeah...she was nice. So anyways I decided to do a test to see if there was someone within the boundaries of Equestria who I could be related to. The result of which lead me to finding out that the princess of friendship and your daughter, Twilight Sparkle, is my biological sister." Starlight said.

"Um...question: Wouldn't the test also tell you that your Shining's Sister as well?" Night Light said.

"The Crystal Empire is not fully Equestrian Territory. It was removed from being considered part of Equestria once Sombra enslaved it one thousand years ago." Shining Armor said. "So trust me, I made sure to check. If the test is for Equestria specifically, then it would only single out Twilight. But there's no doubt in my mind that she's my biological sister as well. You haven't seen how similar she is to Twilight." He explained.

"At least you didn't say a different thing." Starlight said.

"Yeah. I think it's gotten old too." Shining Said.

"Well to be honest, the moment I knew I was pregnant with a third child not even two years after Twilight was born...I knew we just would not be able to handle another child." Twilight Velvet said. "But thankfully, we met your adopted mother when she arrived in Canterlot for a business deal that went wrong shortly before we met her. Believe it or not, but the mare who adopted you was sterile. As in she would never be able to have kids of her own. And we were essentially her saving grace." She added.

"Of all the explanations...you had me adopted by a mare who would never be able to have her own biological child." Starlight said.

"When you say it like that, you don't get the full story..." Night Light said.

"...Before we talked about this, I was half-ready to never accept either of you as being part of my life." Starlight said. "But now I hear how much you were caring for someone besides yourselves and I no longer know what to decide..." She added.

"Just take it one step at a time Starlight." Twilight Velvet said. "We may not be able to make up for the time we missed, but we would love to consider you a part of the family at least." She added. Starlight smiled.

"Well my biological siblings have already accepted me as part of your family so...I suppose if your willing to try, we can make this work." Starlight said.

"That's good." Night Light said.

"So...is it too soon to talk about potential love interests with you, Starlight?" Twilight Velvet asked.

"MOM!" Twilight, Starlight, AND Shining Armor all yelled out at once.
