"After running away from the CMCs cutie mark camp, Rumble finds himself moping around in the Everfree Forest. After it starts raining, he hears a voice beaconing him to take shelter in a nearby cave. The cave is being illuminated by something deep within. The voice instructs Rumble to follow the light. He walks deeper and deeper into the cave, until he finds the source of the light. A tree? Was it the tree talking to him?"
