Everyone in the council watched on with their mouth open except A'Mila, who had a smile. Silka was the weakest member of the council, but they hadn't expected her to lose against Adrian in such a pathetic manner.
On top of that, Adrian also proved that he wasn't much weaker than them, and he endured their mistreatment only because he was at fault.
The council recognised that Adrian had done plenty to earn forgiveness for his small mistake, as anyone from outside wouldn't endure their abuse while assisting them willingly.
Had Adrian truly been against them, he could have just sided with Malachi and caused trouble from within the tribe.
This would have made them vulnerable to Malachi's attack, setting the prisoner, including himself, free. But Adrian chose to help them, going against his kind and doing what was right for the tribe.
