Edinburgh was one to not take advice especially because he believed he was always right. He believed he was better than the other two faction leaders and that had been his downfall.
He had fallen off first because he had refused to accept that he was prone to rushing into situations without thinking them through.
Rochan was a deep thinker; he preferred to go through situations knowing that no matter what he could see possible scenarios that would benefit his own life.
After he heard what had happened with Edinburgh and how he had been taken down through such a meticulous process, he knew he was not dealing with a child and decided to take the bull by the balls.
He knew the only way to defeat Greg would be to fight him at his own pace and that was the hat he was prepared to do.
