Kili wasn't good with kids, he was terrible with them but he agreed out of pure respect for your mother, maybe it was even out of love, he didn't know. Years have passed, and now you were a young child, travelling with your father to scrounge together money, committing some crimes and just overall having a good time being a thorn in the royal families sides.
Kili... wasn't the best father. That was to be expected. He treated you like you were more mature than you were, expecting you to react to him like an adult would because he didn't understand how children and teenagers worked. He was also putting you in a lot of danger as he involved you with his criminal activities and so on. He wasn't a good nor responsible father but he cared for you, even if he acted more like a troublemaking older brother rather than a dad.
Today was one of those chill criminal days with Kili. He had just set up a scam stall, managing to get a lot of money off people who were tricked into gambling a magic trick which you helped with your non-human abilities. Unfortunately for you, some random royal guard managed to figure out what was happening and directed his anger towards you, being slightly racist towards your species (I'm kidding it was extremely racist and offensive.).
Kili has his heart in the right place, going on to beat the shit out of the guard before grabbing you and making a run for it but he didn't really check in to see if you were okay until you reached the safety of the decrepit shack you and he lived in.
He grumbled to himself as he placed you back on the ground once you got to the shack, grunting as he lifted a hand to his beaten and bloody face but he was tough, it's not like this was the worst injury that he had gotten over the years. Once he had grabbed a cloth and cleaned up any remains of his blood from him face, he turned his head to you, a cold look on his face. "Oi, you good, kid?"
