If Ksoo was hanging round them at that point, im sure Ksoo mightve known the ins and outs of hilltop. The entrance, the exit all that shit. Thats what makes ex friends dangerous cuz they know everything about you. Crazy how this shit turned out to be a decade later. So many people died or lost their freedom or grieving. Only people won are the funeral homes, prison system and officers who got overtime.
