Mistakes (a Glee/Supergirl crossover)

That Day

-Three years later-
Today was Kat's third birthday. Ms. Grant gave me the day off, and we were having a small birthday party for her. Even Blaine and Clark were coming! Kat has been really excited about this for about a week now, and today she wouldn't stop bouncing off the walls! I think that she's starting to gain her powers, and I am not excited for when that comes. I hope that it's just normal three-year-old hyper-ness and not her powers. I think that her powers might be dormant until she's in her teenage years. Another thing that happened was about a month ago, was Winn and I started dating(a/n I know that they aren't dating actually but this doesn't happen nearly enough and I think that they would be cute together. Ima stop ranting now baiiii)

-The party-

When Blaine arrived, he told me some unexpected news. The glee club was in National City, looking for Marley. The last time that she was seen by them was at Blaine and Kurt's wedding, and they missed her. Their wedding was about two and a half years ago, and I only went because Blaine is my cousin, and he's like my best friend. He was there for me when no one else was, and I was going to be there for him. He said that he told them that he was going to go on a walk, so he couldn't stay for long. He was there for a warning, and to tell Kat to have a happy birthday, but then he would have to leave. He went and talked to Kat, Clark, Winn, and I. Then, he got a call from a worried Kurt, asking where he was. He said that he just lost track of time and was heading back to the hotel now. He said goodbye to everyone and said that he would definitely come back as soon as he could.
"Bye Blaine! I'll miss you!" Kara said. He said it back and left.

-The next day, at CatCo-

Kara got a message from Blaine. (Blaine Kara)
Kara! You HAVE to get out of CatCo!
Why?
The NDs heard that there was a great hacker/tracker that works at CatCo
Who?
It's Winn. If they show him a picture of you, then he'll call you out! You HAVE to tell him about high school
He already knows about most of it, just text me when you guys are in the elevator
Ok. Looks like I'll see you in a little bit
See ya, Blaine

After Kara had gotten that news, she jogged over to Winn's desk and told him the crisis at hand. He said that he would watch out for them for her. They kissed then went back to work. (Remember they're a couple)

About 15 minutes later, Blaine texted her saying that they were in the elevator and on their way up. She texted back and got prepared for them to come.

When they showed up, they walked up to Kara, and Blaine was the one talking to her.
"Hi" he smiled the smile that he only used with family "Do you know where Winn Schott is?" He asked her. She smiled her smile that was only for family, and Winn came over, hearing his name.
"You asked for me?" Winn said, knowing exactly what was going on. Kara texted Blaine, telling him to meet her by the elevator in 5 minutes. He saw the text, looked up at her, and discreetly nodded to her, agreeing to meet. Kara excused herself, not wanting to spend any more time with the New Directions. After a few minutes, Blaine slipped away to talk to Kara.

"What is going on?!" Kara demanded.

"They missed you, Kara! You can't blame them for looking for their missing friend!" Blaine replied, not wanting her to go all Kryptonian on him. Unfortunately for them, the New Directions finished up and were at the entrance to the area the elevator was in. They heard everything.

"Look. Blaine. I thought that you were going to help me keep them away! I can't deal with them being here, especially right now. Blaine, please tell me that you will help me stay hidden." Kara said.

"Fine.  But, what do you mean by 'especially right now'?" Blaine asked.

"Kat's asking questions. About... him. And I've actually built a new life here. I can't have them come here and tear it all down." Kara sighed. "I'm gonna head back to work now. You gonna come over for game night tonight?"

"Yeah. I'll see you there Kara. Bye!" Kara turned around to go back to work, but stopped, seeing the New Directions standing there.

"Oh crap," she muttered under her breath. "Hi! Can I help you with something?" Kara asked them.

"You're Marley," Jake said, speaking for the whole group. "Why did you lie? And why did you not tell us?"

A/N

Hey guys! So, I know that this is a bit late, but I wanted to make it longer than this. I obviously failed at that. Hope you liked it! 

See you in the next one!
