You are the Chosen One (before the fight)

The Dark Lord had disappeared from your sight a long time ago which was strange, he and you were always together, seeing him away could only mean that he was up to something, and you were right after all

The Dark Lord went to a forest to do who knows what and when you found him he was holding a child of + or - 4 years old, he was smiling and playing with the child who for some reason wasn't scared, But I didn't say anything either

you went to ask the Dark Lord what was going on and he told you that he had found the lost child, you can tell he became attached to the child instantly, which would be a big problem, not just because you two are literal.. .huh, criminals? thieves? Murderers? What other adjectives fit here?

"Hey! We can't leave her here! And don't tell me I'm not responsible... I am! I'll take good care of her!"

you and The Dark Lord started a peaceful argument, a little loud, but this made the little girl start crying and The Dark Lord, despite trying, was unable to calm the child
