Sapnap walked up to the rooftop of the school after Karl had sent him a picture from there with the caption 'look where I am right now' He found Karl sitting against the edge, legs dangling. Karl was clearly struggling with something. Why else would he be so close to the edge? He stood behind Karl before sitting next to him, looking down. "Why are you up here?" He looked over at Karl, whose head was staring at the ground.
