Christmas was always Kara's favorite time of year. It had been from the moment she landed on Earth. Even Alex, who didn't like her at first, was nice to her during Christmas time. Christmas was just so full of goodness. Kara loves the idea of exchanging presents. That is perhaps her most favorite part of Christmas, although she certainly appreciates the excuse to eat as much food and sweets as possible.

Gift giving is special to Kara because it allows people to really demonstrate how much they love and appreciate each other. She still has the first present Alex ever gave her during her first Christmas on Earth - a Webster's dictionary. Eliza and Jeremiah had criticized Alex for the gift at first, after all, it was Alex's old dictionary. But Kara cherished it from the moment she opened it, because in it, Alex had inscribed, "Dear Kara, this book is to help you learn more about English. Maybe one day, you will know enough words to tell me about your life on Krypton. Maybe this book will help you discover more about my world. I have highlighted important words that you should know. Love, Alex." The book did help Kara learn more about the customs on Earth and more about Earth's history. Eventually, Kara was able to share some things about Krypton with Alex. And when Kara first became a reporter for CatCo, she brought her trusty dictionary with her.

And so, holding the tradition of gift-giving in the highest regard, Kara was now sneaking around the storage rooms of the DEO. This Christmas would be the first Christmas that Lena would be spending with Kara and the Superfriends. Having met Lillian a handful of times, none of which were pleasant, Kara could only imagine the types of Christmases that Lena had experienced in the past. And that did not make Kara happy. Lena was just so good and she deserved to the best Christmas ever. So Kara was searching for the perfect gift. A gift that would let Lena know how special she was. A gift that would show Lena just how much Kara cared about her.

The DEO has a special archive of items from Krypton. Kara rarely looked in the room the archive was stored in, because the first time she went in there, she was too overwhelmed with emotions and started bawling. Alex subsequently banned her from the room without supervision, and since Kara had had such a strong emotional reaction to seeing the stuff from her dead planet, she decided not to fight Alex on this issue. But this was a unique circumstance, and Kara had the perfect idea for a gift for Lena.

Unfortunately, with very limited space in the DEO compound, the Krypton stuff was stored with a bunch of other items from other planets and galaxies. Not all of these items had been properly tagged and some of them possessed properties that were mystical. And that is how, the night before Christmas Eve, Kara found herself reaching for a special necklace from Krypton and instead grabbing hold of a sphere from the planet Monorida. And, further, how the next morning, Alex found her sister in a storage room of the DEO as a very confused and scared fifteen year old.

"Kara!" Alex yelled, looking for her sister in the DEO. It was Christmas Eve and it was unlike Kara to disappear on the day before the most magical day of the year. Kara loved Christmas. And that is how Alex knew something was wrong.

When Kara didn't wake Alex up at 6 in the morning on Christmas Eve, as per Kara's rather annoying tradition, Alex became worried. Kara always woke Alex up at 6 AM. 6 AM was when they began making Christmas cookies, only some of which were reserved for Santa, who Kara swore was real (Alex tried telling her that he was a myth, but then Kara said something about a different planet and since Kara was an alien and had special powers, Alex figured that maybe Kara was right), and made hot cocoa and watched really cheesy Christmas movies.

"Kara!" yelled Alex again. Since Kara wasn't at Alex's apartment, her older sister first looked at Kara's apartment. Upon not finding her there, she decided to look at the DEO. CatCo was closed, after all, and she couldn't think of anywhere else Kara could be. Plus, she had already called Lena and confirmed that Kara was not with her, although that just made the CEO worried, so Alex decided it would be best to find Kara immediately, before the CEO started asking questions.

After fifteen minutes of searching all of the usual spots in the DEO, Alex heard a small voice whimpering. Following the sound, she eventually came to the storage room that Kara was in. Seeing which room it was, Alex was a little frustrated at her sister. She knew that Kara always felt a little lost during the holiday season, even though she loved it, because she wished she could share her new Earth traditions with her Kryptonian family. Which is why Alex had banned her from the Krypton room, especially during times of great emotion for Kara. And now Kara was locked in the room, crying.

But when Alex opened the door and instead of her twenty-four year old sister, she found a fifteen year old version of her sister, her eyes opened wide.

"Shit."

Kara stopped whimpering and looked at Alex with anxious eyes. "Who are you? You look familiar."

"I'm Alex, Kara, your sister."

"You're not Alex, but you do look kind of like her, if Alex was old. But Alex isn't my sister. Alex said she will never be my sister. You're lying! Who are you? I have powers, you know, I could hurt you."

Fuck, thought Alex. She has memory loss, too, and damn, I was an ass to her as kids.

Raising her hands in a pacifying manner, Alex adopted her most reasonable tone of voice. "Kara, it really is me. and I'm sorry for saying that. But, look, something has happened to you. And I need to know what you did so I can fix it. How did you get here?"
