09 - The Edge
We've already covered two immovable objects, but what happens when two unstoppable forces meet?
Sometimes, they cancel each other out. Usually, they destroy each other (and much of the world around them in the process). However, very rarely, they resonate. When two unstoppable forces resonate, neither heaven nor hell can stop them.
Lucky for all afterlives and related bureaucratic bodies, these two didn't want to do much that warranted stopping. To be honest, they were just chilling.
