Jason didn't expect Brell and the former tribe chief to have a master-disciple relationship.
Thus, he couldn't help but stare at them even after the former tribe chief seated himself on Brell's chair, while Brell accessed his spatial ring to retrieve another chair to sit a little bit behind his master.
This clearly showed how highly Brell regarded his master.
Jason felt that this was a great advantage, and the fact that he had been able to defeat the former tribe chief, whose name was still a mystery to him, played into his hands.
Yet, contrary to his expectations, the other tribe chiefs didn't seem pleased about the arrival of Brell's master.
Rather, they were staring daggers at him, which Jason didn't expect to happen.
Because of that, he was unable to make an assumption about what would happen during the next few minutes.
Luckily, he heard the former tribe chief talking to Brell, and Jason was able to hear his name too.
