A World Where You Can Be Both

So...this is...super late...
Sorry! Real life kept getting in the way. Hope this chapter makes up for it :-)
Warning: the following chapter contains high amounts of tooth-rotting fluff. Author is not responsible for cavities, sore jaws from smiling too much, or sobbing fits.
Now that that's settled, onward!

Mon-El awoke in a way he hadn't for the past ten years; slowly and contentedly and not at all ready to get up. Especially with the sight that greeted him when he opened his eyes.
    Staring into Kara's sparkling blue irises, Mon-El couldn't help the smile that spread across his face, matching her own. The brightness of her cheek would shame those stars.
    "Hi," she said softly.
    "Hi," he whispered back. He had half expected her to be gone when he woke up. "You stayed."
    Kara scooted forward, laying her head over his heart as he wrapped an arm around her back. "I missed waking up with you."
    "Me too," Mon-El whispered, almost hesitantly. He was afraid that this was all too good to be true, that he'd wake up in his cold lonely bed on the Legion ship, Kara's warmth a distant memory. 
    "As much as I'd love to stay here forever," he muttered, "I think your alarm clock has other ideas." 
    Kara groaned when, sure enough, the device on her bedside table began to beep loudly. "Way to ruin the moment..."
    Mon-El laughed as he reluctantly got up, searching for his clothes. "Wouldn't want to be late for the wedding."
    "Speaking of which..." Kara said, pulling on her dress, "Do you think Winn would be okay with waiting a few days to go back to the future? I need some time to say goodbye to everyone."
    "Yeah, of course. I'll talk to him," Mon-El said as he buttoned up his shirt. It was hard to believe this was really happening. She was really coming with him.
    He paused, taking a deep breath. "Kara, are you...sure about this? Leaving everything behind just to come with me to the future?"
    Kara stopped getting dressed and walked over, setting her hands firmly on his shoulders. "Absolutely," she said, lips curling into a smile. Her tone turned playful. "I want to help you keep the world spinning."
    Mon-El chuckled softly. He remembered saying that when he first decided to be a hero. Kara had inspired him more than she could ever know.
    "I love you," he said almost involuntarily. But who cared? After all that had happened, they were together finally and he could say he loved her as much and as randomly as he wanted.
    Kara bit her lip in that adorable way, a light blush covering her cheeks. "I love you too," she said shyly. "Always."

    Kara adjusted her glasses, her gaze sweeping across the crowd. Everyone had huge grins on their faces, ecstatic to be here, and Kara was no different. She had watched her sister struggle with love and being a mom and being herself, and she was so happy to witness Alex getting it all.
    Especially when Kara was, too. She glanced at Mon-El standing next to her and he smiled encouragingly. This was one duet they would happily sing.

We belong to the light
We belong to the thunder
We belong to the sound of the words
We've both fallen under

    Alex entered and walked down the aisle, clinging to J'onn's arm. He had on his proud papa smile, and Kara didn't think she'd ever seen either of them so happy.

Whatever we deny or embrace
For worse or for better
We belong
We belong, we belong together

    Kara and Mon-El turned and smiled at each other with that line, eyes twinkling. A lesson learned the hard way, but one they would never forget.

Close your eyes and try to sleep now
Close your eyes and try to dream

    Esme walked down the aisle tossing petals, looking like a little angel with her flowery dress and toothy grin. Alex leaned forward to wave at her daughter as Esme reached her chair and was pulled in for a kiss to the head from Eliza.
