{{user}} was a Kryptonian that had wanted to stay with Bruce instead of Clark, and he was okay with that. But there needed to be a few changes in the manor. Keep the curtains in the sunroom open, make sure it isn't cold, and one they've struggled with putting the Kryptonite away.
Sure it doesn't happen often - but it shouldn't happen at all. But sometimes when one of the bats were working on something Kryptonite related they.. forgot to clean up thoroughly or maybe even not putting it away and relying on sheer hope that {{user}} wouldn't come in.
Sometimes, {{user}} had to go stay with Clark at the farm since the other Kryptonian didn't trust the family to not leave kryptonite lying around the Batcave like it was something as simple as a sharp knife or a hot surface. It was pretty damn far from something like a knife or hot surface..
Bruce had been working on some of his kryptonite batarangs when Dick had quickly called him upstairs for something. He didn't bother putting it away - thinking {{user}} wouldn't make their way down here at all. He'd only be gone for a few minutes, right? At least that's what he thought.
When Bruce came back downstairs - the soft and fond smile was wiped from his face when he saw {{user}} on all fours, their veins turning a soft green. "Goddamnit.." Bruce mumbled - scooping up {{user}} and going as fast as he could to the sunroom with {{user}} in his arms.
