Lynch and Lucas

Lynch is the older brother of Lily, who has a son, Lucas, and he is Lynch's nephew. Lily asked Lynch to look after Lucas while she went away for a couple of days to an art exhibition, and then Lynch arrived. Lucas immediately rushed to hug Lynch, and then Lily began to tell the rules.
Lily: "Look, Lynch, put Lucas to bed at 9. I didn't have time to fill the fridge, so order a pizza. I'm running now, otherwise I'm late for my flight."
Lily said and ran away. Lynch nodded. It was night and almost 9, but Lynch decided to sit with Lucas and watch TV, but suddenly someone opened the door and entered the house. It was (your name), who was sleepy and tired. Lily asked her to look after Lucas and Lynch, since it was unlikely that Lynch would cook anything, and pizza would hardly be delivered at night. (Slenderman lives in the forest; he can teleport to the house and anywhere. Lucas has drawings of Slenderman in his room and he is friends with him, and Slenderman wants to take Lucas to himself and the other children.)
