Advent Calendar: Day 1

Kurt and his daughter's first time Christmas tree shopping after Sebastian's death.
~650 words

Warning: Mentions of major character death

A/N: I plan to write every advent calendar prompt as painful and angsty as possible. Be warned.

"Daddy!" Madeline tugged on the bottom of Kurt's coat sleeve. He broke his gaze from the rows and rows of full pine trees, looking down at her. "Aren't we going to get our hot chocolate first, like always?" She looked up at him and he couldn't help but get lost in her twinkling blue-green eyes that looked so like his own.

Every glance into them was a reminder that Sebastian was truly gone. Nothing remained, not even a child of his own genes. Logically, Kurt knows that if they used Sebastian's sperm, he wouldn't have Madeline, and she really did mean the world to him, especially now. But a darker part of his mind wished that he had insisted more on Sebastian being the biological father just so Kurt would have some piece of him left behind, someone who might have inherited Sebastian's snark and challenging attitude or his critical mind and level-headedness. His train of thought only left him with a crushing weight of guilt on his chest. He tried to mentally shake it off, assuring himself he wouldn't trade Madeline for anyone in the world.

"Of course, sweetie," Kurt finally replied, taking her hand and guiding them to the little snack station.

"But are you gonna have some, Daddy?" Madeline asked when they stepped in line. "We have to buy two."

Kurt paused. He didn't usually indulge. This was Sebastian and Madeline's thing—grabbing hot chocolates before they ran through the rows, inspecting each tree for "fluffy quality" while Kurt walked a few steps behind, watching them fondly. Damn, Sebastian really would've been better at this than him. For not the first or hundredth time, Kurt wished he drove to the store that day instead of making Sebastian go.

"Sure, I'll get one. And you can even get extra marshmallows," Kurt told her. Madeline immediately bounced a little more in excitement.

"You never let me get extra, Daddy."

"Well, it doesn't matter so much anymore," Kurt said, shrugging his shoulders. They finally ordered their hot chocolates, starting down the first row of trees. Kurt's hot chocolate sat in his hand, untouched. After the first row, he tossed the full cup in the trash with Madeline's empty one.

"What about this one, Daddy? Or is it too small?" Madeline asked, running up a little to point at one on their left.

"That one's fine, Maddie."

"I think it's too small," she declared, grabbing Kurt's hand and pulling him into the next row. They walked for a few minutes before she spoke again, "What about this one? There's no bald spots."

"Looks good," Kurt answered. He pulled out his phone to check the time.

"Daddy!" Madeline shouted, almost indignantly. Kurt looked up to find his daughter, arms crossed and with a furious expression, but she clearly couldn't help the tears escaping from the corners of her eyes. "We're supposed to pick this out together. You don't even care how our tree looks. Papa's not here to help me or make you help, so you just need to, okay?" Kurt immediately snapped out of his self-brooding as Madeline's tears racked into sobs. He gathered her in his arms, not fitting as well as she used to now that she was nine, but it did the trick. She wrapped her arms around her dad's neck, crying into the crease between his neck and shoulder. Kurt rocked and swayed her slightly, ignoring the concerned looks from other parents and couples.

"It's okay, sweetie," he murmured into her hair. "I'm sorry, okay? Daddy's sorry. I'll help you pick it out, I promise. We'll get a really fluffy one with no bald spots, alright?" Madeline finally quieted, nodding and disengaging herself slightly from her dad's hold. Once she was back on the ground, he curled his hand around hers, pulling her forward. "Let's go find a perfect one, alright? That one was a little too small." Madeline nodded, giving Kurt a watery, painful little smile as they continued on.
