People were searching for Alex everywhere. In this area, Alex's death meant every other person's relief.
If Alex died, then the second sub-scenario would be over, meaning no one would have their difficulty level increased in the next scenario.
No one actually had anything against Alex; they were quite scared of him, but by now, everyone knew that Alex didn't have a leg, so they started tracking him down.
The group of leaders, then ones that had thought that there was no way they could win, now had a new flame burning in their hearts.
But still, not all of them wanted to fight against Alex, not when he could move without any restriction.
Alex had never lost a fight or so was what everyone knew.
Even if this was wrong and Alex did lose a fight, he was still a monster. During the time all five leaders faced off against Alex, they realized one thing: If Alex was allowed to move, then they would die even without knowing where the arrow came from.
