Disclaimer: I do not own any of the characters, places, events, etc. that come from the CW's Smallville. Kir-El and her adventures are all mine though.

Authors note: These are a series of tropes that pop into my brain as 'what if' scenarios. Several will be crossovers. If you have any ideas or requests I would love to hear them and see what I can do. Also constructive criticism is always welcome. Thanks for reading!

Clark sat at the kitchen table staring intently into his mug of coffee trying to digest the newest curveball life decided to chuck his way. He took a sip, grimacing to find it had gone cold. Setting the mug back down with a sigh he tried once more to wrap his mind around the idea that another Kryptonian had survived, he wasn't the last one anymore. Kir-El, his sister.

He had a sister. How weird was that? But amazing at the same time. There was so much she could tell him, teach him about where they came from and what Krypton was like. And she had been looking for him, searching all this time. Clark could help but wonder, he had let down his friends and parents so many times, what if he let her down. What if he couldn't live up Kir's expectations and disappointed her too? What if she decided that she hated him and left?

The sound of a chair being pulled out jerked Clark out of his brooding. He looked up to see Kir sitting across from him her expression blank as always but something in her eyes made him think she was worried.

"You are troubled."

Clark huffed, "Yeah, it's a lot to take in you know." Kir nodded. Neither spoke for a while, the only sound came from the old clock on the wall ticking away the minutes. With each tick the questions buzzed more and more incessantly around his brain demanding answers until Clark couldn't stand it anymore.

"Why?" he finally asked. She cocked her head to the side reminding him a bit of Shelby. "Why did you look for me? You could have gone anywhere in the universe, done anything you wanted. Why waste any of that time looking for someone you weren't even sure existed anymore? Why did you even want to? What were you planning to do when you did? Now that you have?" He shot the questions out in one long breath.

Kir took a deep breath. "Clark," she began softly, "I looked for you because you are my brother, my blood. I couldn't settle anywhere in the galaxy or beyond knowing you might be out there somewhere. That you might need me somehow."

She sighed leaning back in her chair. "The initial plan was to take you from where ever Jor-El had placed you and raise you myself. As the years dragged on and seeing what you have here, I am hesitant to follow that course of action. I want to be a part of your life, even if it is a minor one." Briefly she looked down, when she spoke again the words seemed strained as though she was forcing them through her throat. "But if you want me to leave. I ….will go. If, that is what you wish."

"NO!" Clark looked up panicked. "No that's not it at all." He wasn't sure but he could have sworn that her shoulders slumped just a little after he said that.

"Then…"

Now it was Clark's turn to duck his head. "I'm always disappointing everyone, and letting them down. I just don't understand why you wouldn't run when you had the chance. Everyone else does."

A hand on his leg brought his head back up. Kir had crouched in front of him. Cupping his cheek with her other hand she looked directly at him.

"Kal-El. I do not know who has led you to believe that you are worth leaving behind but I can assure you that you are not. You are my brother, and I care for your health and happiness with every fiber of my being. No matter what the circumstances or obstacles that stood in my way I would never have stopped searching for you. I'd like to believe that there is not a single instance in any reality where upon learning I had a brother to watch over and protect, that I did not shake the stars, and raze whole worlds, just to find you. That is how much you mean to me."
