"I'm right here," Achilles promised Patroclus. "Don't let her see fear." No god should ever see fear from them. Even in the face of Zeus himself Achilles had relinquished his fear. He showed his respect but he would not let something take him over in that way. Any fear he held was kept behind closed doors. To his dreams, to his nightmares, to the future he was uncertain of, and to the past. It in no way would be due to some other being.
Achilles stepped past Patroclus, locking a watchful eye over her. "I'll speak with her." He wanted Patroclus to stay back. "Stay with Polyxena." At those words he dropped her hand.
