An apology
In the end, the boys just couldn’t take it anymore. A lot of people that once spoke to them normally were now treating them like the plague. They wanted things to return to normal, but they knew what it would take for them to come clean about their actions and what they did.
The only question was if they would have the strength and conscience to finally admit that they were the ones who destroyed the rock. What would the consequences be for them and would it fix everything? There was only really one way to find out for certain. They needed to apologize to everyone.
