Hunters=Brave People

The group arrived to San Francisco and met Annabeth's father and told him that his daughter was in danger so he immediately drove them to Mountain of Despair. Here was the place to which Luke, the manticore, and the General will arrive so they can build the mountain and turn it into the new Olympus after defeating the gods. The group fought against the enemies, rescued Annabeth, and destroyed them, but Zoe was killed by the Titan Atlas who was the General and Zoe's father. After completing the quest, they arrived to Olympus, where they were honored and congratulated by the gods. Blackjack and the pegasi brought the group back to camp half-blood and Percy called to mom and Tyson by an iris message. Nico realized that Bianca died and wanted to kill Percy, but suddenly four skeletons appeared, Nico destroyed them, and after that he was gone.

"He will not hurt me." Zoe said this because she is courageous and is convinced that she can destroy a big dragon that was the guardian of the door that guards Mount of Despair.
"You never had any courage, sister." Zoe said this to her sister that appeared there to alert the group that they should not enter to Mount of Despair. Zoe is confident that she can kill the dragon and once again, she demonstrated that she is courageous.

 The Hunters of Artemis are very courageous people and they will do whatever it takes to save a quest if it is necessary. At Phoenix's desert, Bianca died because she killed a monster to save the other members of the group. After that, Zoe also died after being poisoned by Atlas when fighting him. If there is a word to describe Hunters' personality, that word is brave.
