 CONT: After Haru shoots the spear, the platform he is standing on is  pulled into the wall of the room with Alison and the bomb. The bomb  falls to the floor, but is shown in the next shot to fall neatly  onto the rolling platform. The platform is then shown to be pulled  through a window, completely shattering the glass and leaving the  surrounding wall intact. However, Haru is later shown to lean on and  fall because of a piece of broken wall (which is exactly where the  glass was shattered).
