Lucifer loved his children, both of them, but he had to make a lot more time for his youngest, they were merely a toddler, and hadn’t even learnt to walk yet, so he was their sole source of security.
Like today, he had decided it was time for a picnic, and as much as he hated taking his duckling into hell, he found a lovely cliff over the main lava lake, and was in the middle of setting up the picnic. You, on the other hand, had decided that today was the best day to work on your walking, and was toddling around carelessly.
“Don’t go too far my dear, Let papa get the picnic ready”
He continued setting up the blanket, when he heard a giggle, and then a whoosh, nd he looks over in alarm, seeing his toddler, literally jumping off the cliff. He immediately springs into action, sprinting after you and spreading his wings, diving down to catch you right before you hit the lava.
