After buying supplies from Benzo's shop, Jayce returned to the workshop and discovered that it had been broken into. During the chaos, a child knocked over an unstable crystal, causing an explosion that caught the attention of Heimerdinger, the authorities, and the Council. During the trial, Jayce revealed his research on using science to channel magic, which caused fear in the Council. Bolbok suggested exile, but thanks to the intervention of his mother and Heimerdinger, the punishment was reduced to expulsion from the Academy.
Jayce couldn't take it anymore, the loss of his research was unbearable. So there he was, in the building where his old workshop used to be. He approached the edge, realized how high it was. He couldn't believe he was going to do this. He was going to jump.
