"Okay, so here is another for you." Lena smiled as she passed Kara a rectangular shaped present.

Kara smiled gleefully as she shook it gently, "It sounds interesting."

"When you open it, it will be more interesting." Lena smiled as she sat cross legged in front of the fire with thw superhero.

She watched as Kara avidly tore away the red paper from the gift. Her smile brightened once again, but then the smile turned into a frown.

"It has..." Kara then noticed the numbers on the doors, "It has 24 doors..." She read the box, "24 chocolate treats-" Kara then gasped, and looked at Lena, "I have seen these but Alex never wanted me to get one...She thought I'd eat all of the chocolate at once...That's the point, isn't it?"

Lena chuckled as she eyed the brightly coloured box, "It is a little late now, but it is called an advent calendar. The point of it is, there is a chocolate for each day from the first of December up to Christmas Eve..."

Kara looked appalled, "Why would anyone wait a whole day for a chocolate every day? Why not eat them all at once?"

Lena laughed, "This is the challenge for you. You can have a chocolate now and then wait until the morning to have another and every day will go like that."

"Pfft, yeah right. As If I'd do that." Kara laughed.

"That's why there are rules."

Kara's heart sank and the smile was wiped off of her face, "Rules? There are rules to this calendar? I thought it was one for every day?"

"Yes, but I know you." Lena smirked, "If you eat the entirety of this calendar at once, you are not allowed Pot Stickers for 24 days."

A pout appeared on Kara's face, "You can't do that."

Lena took a breath, "I believe that I have found Supergirl's biggest challenge yet."

"You are cruel." Kara hissed.

"I know, it must be the Luthor in me." She grinned devilishly.

"You." Kara growled playfully, "This will be so hard."

Lena giggled as Kara passed her a gift, "Here you go."

Lena accepted the gift and smiled as she looked down at it, "Whatver could this be?"

"Open it, find out." Kara smiled.

Lena briefly glanced at the TV, "I'm guessing Doctor Who is on after this?"

"Yup." Kara smiled and reverted her attention to Lena as she finished unwrapping the gift.

Lena's face lit up. She opened the box and saw a silver plated House of El symbol necklace. The gaps were filled in with a black paint.

The Luthor's jaw dropped, "This is beautiful." She spoke softly.

Kara sat chewing on a candy cane, and smiled smugly, "Look on the back."

"Of the box?"

"No, silly. The coat of arms." Kara smiled.

Lena glanced at her briefly and gently turned over the plated silver, and it read, 'A friend means so much more, and your heart is gold and pure.'

Lena felt a tear running down her cheek and looked up at Kara, "Thank you." She said in almost a whisper.

She then chuckled, "You know, my mother would have a field day if she saw me wearing the symbol that is associated with the Supers."

Kara leaned forward, "She'd have even more of a field day if she knew that her daughter was screwing one of them."

Lena laughed at this.

Kara was so daring around her, almost like she was using the Supergirl attitide with her when she was flirting.

Nontheless, she liked it.

"And what's more, if it goes missing or if by chance, you get kidnapped again...It has a tracking device inside and is bullet-proof."

"How very thoughtful of you." Lena said modestly, "And what with the attempts on my life all the time...And when mother finds out, which I have no doubt she will...I will get kidnapped again."

"On a lighter note though, I will be able to find you, so it is a win-win situation." She smiled.

Lena kissed her slowly, "Thank you."

Kara looked at the TV, "Doctor Who is about to start!"

Lena smiled and followed her to the sofa. The Luthor leaned on Kara's chest.

Kara hummed in delight as she found the box of chocolates on the floor beside the sofa.

She unwrapped one sweet and put it in Lena's mouth for her.

Lena smiled, "Thank you honey."

"Did I tell you how cute you looked in glasses?" Kara asked softly.

"The same could be said for you." Lena said softly, before grabbing the discarded blanket from the end of the sofa and draping it over them.

15 minutes later

Kara was chomping away on chocolate and was in awe of this programme. Doctor Who was beyond fascinating.

"So, he fights creatures from outer space like me?" Kara asked with a mouthful, "He is similar to Kal and I."

Lena playfully hit her on the arm, "Do you ever watch TV without talking through it?" She said with a smile.

"He can travel in time! That is so cool!" Kara gasped, getting giddy.

"I will tell you all about him afterwards if you stay quiet for the remainder of this."

Kara obliged, resting back into Lena's stomach.

45 minutes later

Kara's jaw could have been on the floor as she stared at the TV. Lena couldn't quite make out the expression and it amused her.

"Kara?" She asked softly.

"He's..." Kara began, still staring at the TV.

Lena gave her a moment, "Now...There is one thing you don't know about me. I'm actually a nerd at heart." She chuckled placing a firm hand on her chest where her heart was.

Kara eventually looked at Lena, "He just turned into a woman! That is extraordinary!" She gasped, almost breathless.

"And he met himself...He has a machine that is bigger on the inside, he fights aliens, he has a box that can also travel in space as well as time! Did I mention that he is now a blonde, and quite attractive woman?"

"Hey! Eyes on me Zor-El." Lena chuckled, as she sat up, "Would you like me to explain?"

"Please." Kara said avidly.

Lena happily obliged, "Buckle up kiddo."

Kara got flustered, closing her mouth.

With a smirk, Lena switched off the TV and gave Kara all of her attention.

"The Doctor is a Timelord, he can do this thing that is basically a way of cheating death. That is called, regeneration. It changes every single part of him, and the bottom line is that this alien can change into anything. But mostly for the past 54 years it has been male actors in the role."

Kara nodded, in awe.

"And now for the first time in the history of Doctor Who there is a female incarnation of the Doctor taking over the TARDIS." Lena smiled, "Okay, so that was basic. Now let's get into the other stuff, but before we get into it..."

Lena knew some of this information would be relateable in some aspects even though it wasn't real, she was worried that Kara would take it to heart.

"Kara this is a purely science fictional show okay? It isn't real and some aspects of his story might relate to you and your cousin in some way." Lena said softly.

Kara chuckled nervously, "I know it isn't real."

"But I know you." Lena said pointedly.

Kara went quiet at this point. Lena had a very good point.

"Okay, so the Doctor is believed to be the last of his kind, and when the show came back in 2005, we were all under the impression that he was the last."

"How? How did he become the last?" Kara asked eagerly.

Lena sucked in a breath, and took a moment. She looked into Kara's blue eyes and was reminded at how sensitive she was.

"On his planet, there was a war. The last great time war, as it was described. It was a war between his people and a race called, The Daleks. The Doctor made a grave descision that haunted him for years, hundreds of years."

"Uh-huh." A deeply enthralled Kara replied simply.

"He had this device thay he used and he destroyed his planet and he ran away."

"But he had no other choice, right? My parents sent Kal and I away because there was no other option. My parents died and Krypton was destroyed."

Lena could tell she was getting too into it, "Remember Kara, this is fictional, but yes, the Doctor had no choice. If the Daleks won, they would have carried on destroying and killing. The Doctor ended it. However, when Doctor Who turned 50 in 2013, they made a special episode."

"Oh?" Kara said with excitement in her voice.

"The Doctor didn't destroy Galifrey, it is hidden away, safe. He is-She is trying to find it again. His kind survived."

Kara smiled with relief, "A happy ending?"

"Yes." Lena smiled.

"It seems like she is the one that runs into trouble and solves the problem easily even though people end up in danger anyway."

"Doesn't that sound like someone I know?" Lena said with sarcasm, "We should have a Who marathon, just you and I."

"Can we?!" Kara gasped, "All 54 years?!"

"I was thinking the past..." She pondered, "The past twelve years, but why not? You really want to go from 1963 to now?"

Kara nodded eagerly.

"It will take a while." Lena chuckled.

"I really don't care." She then gasped, "We can invite Maggie and Alex for Whoathons..."

"Who-athons?" Lena only laughed.

Kara frowned, "I will work on that one...But Winn is a Star Wars nerd too! He has only ever made one Doctor Who reference that I know of." She added quickly, "I'm pretty sure he wouldn't turn this down."

"I'm sure he wouldn't, however I must warn you, there are some episodes of the original- Sorry, classic Who that are missing."

Kara then pouted, "But Doctor Who is the best ever! How could they lose them? Did they leave them down the back of the sofa?! No! They are lost in the TARDIS, it's bigger on the inside."

"Is it, I never really noticed before." Lena said with sarcasm, before taking a breath, "Which part of Krypton were you from?"

Kara looked confused, "Uh...The...North?"

"I cannot wait until you get to these Who Marathons. I can tease you for making references in every day life and you wouldn't even be aware." Lena smiled, holding back a laugh.

Kara was still confused, "She has a ship that is bigger on the inside."

"You love that part."

"I can't get my brain around it." Kara gasped.

"I think the fourth Doctor explained it at one point."

"I'll find out." Kara said eagerly.

9pm

"Luthor! I am going to kill you!" Alex snapped through the phone that was sat on the coffee table on loudspeaker.

Kara lay on the sofa with an arm wrapped around Lena, "Kill with kindness Alex!"

"Let me rephrase that." Alex said with a tone that sounded borderline sarcastic, "I will kill you with kindness."

"What did Kara do this time?" Lena asked with a small laugh.

Kara looked offended, "Me?! I didn't do anything."

"You." Alex began, "Have been texting about Doctor Who for the past two hours. Four hundred and Fifty messages."

"Oops." Kara said with a pout.

"I can hear that pout Kara." Alex said through the phone.

"Lena said she could hear my pout too. How do you do that? Do you two have special powers?" Kara frowned.

"It's a talent." Both Lena and Alex replied at the same time.

Both Alex and Lena went quiet for a moment.

"I do apologise agent Danvers." Lena spoke up first, "She has probably been googling for the past two hours."

"Kara, text Winn...And..." Alex began, "Lena, since when were you a nerd?"

"It's a talent." She shrugged, "I think it is beginning to crack dawn over there. We will leave you to it. Happy Christmas Alex."

"Merry Christmas Luthor- Lena." Alex corrected, "And you too Kara. Just stop texting about that show for a bit please."

"Love you Alex!" Kara shouted through the phone.

"I love you too Dummy." Alex smiled, before the phone went dead.

AN: Merry Christmas Eve everyone. One chapter left I believe. I might throw in an extra on boxing day.

Thank you for the feedback.

Yours truly.
