"Y'all are way too tense. Have some fun, and swing your butt to whoop the monster's asses!" Dilan calmly suggested.
He didn't plan to kill the Ascenders of the Blue Star camp. It would be way too annoying to attack Mayor Clerens, Sheriff Jennie, and Hunter Jared head-on.
It was not impossible for him to kill them, and Dilan was confident of defeating them if he would be honest with himself. However, it wouldn't prove any benefits to him.
The Blue Star camp could be said to be an additional defensive layer against groups of evil Ascenders. The fact that the group the bloodthirsty Ascenders belonged to openly attacked the Blue Star camp was a great precursor for Dilan's behavior.
Nonetheless, the fight against the monster tide was way too long and drawn out, and Dilan worried that the unconscious bloodthirsty Ascenders would get hit by an astray attack, or bulldozed the moment the monsters of the tide were to be able to push a few Ascenders of the Blue Star camp away.
