In the end, Ace found himself alone with Andrew Dawn to discuss matters.
According to Andrew Dawn, Ace's teammates already knew everything he wanted to convey, and he was the only one left out. There wasn't much they spoke about among themselves, but the brief conversation was enough to brief Ace on many details.
After discussing a few other important things with Andrew Dawn and giving his word that he'd assist in keeping the ogres from gaining an advantage in their pre-fight preparations before the war, Ace was going to go his own way.
Andrew Dawn believed Ace was too strong to be part of a team, even with his team consisting of strong members.
While they were stronger together depending on the situation, the task Andrew Dawn had for Ace seemed suitable for him to handle alone.
After they exchanged their thoughts, Ace and Andrew Dawn parted ways.
