Altercation
"You want to fight?" The man said, as his craziness got worse. "We can do that but first you need to join my guild!"
Jayce didn't even think twice before saying his answer.
"No."
As for whether or not Jayce did want to join Brightdane, it wasn't up to him. Oliver and now Rose knew about Nightmare which they could use to blackmail him if he chose to leave the Academy.
Then there was the fact that he himself didn't want to join Brightdane. There was Bella, who was teaching him Limitless, Ashley who had made friends with both Bella and Yuko, and the fact that the Headmaster and Ms. Moore knew had seen him use demonic energy.
He had too much at the Academy to up and suddenly leave; yet none of these were the most important one. Jayce didn't know if Brightdane was the S-rank Guild who was cooperating with the D.A.
