This is slice of life moment, and I imagine a tru sibling interaction.
Allen and Katherine were spending time in the living room, Katherine was dancing after the dancing show on television, and Allen wanted to turn down the TV's noise while trying to read. So they might have a small argument, which resulted in one victim of grandmother's crystal planter.
Allen and Katherine knew that their strict grandmother would give them a bad time. Luckily it was their father who found them on "the crime scene". Daniel is less strict than Madelyn. Nevertheless, he wasn't happy with siblings performance, as they turned the blame on each other.🤥
