What kind of a person went into a competition knowingly and also sleep deprived? She would be disappointed in Sasuke if she were aware of this.

If he was going to be polite because of the company, though, then she would take full advantage of that. For the greater good of the team. "That would let teams like the one your brother is on get an advantage in scarf number over us! Sensei is out there, too, and he won't tire out any time soon." She shook her head, frowning determinedly. "No! The only way to compete is to use our advantage of early placement to go out there and catch the weak fish first! Then we'll be ready to take on the teams that have your brother, Sensei, and Kakashi."

And that would also keep Sasuke from slinking off and trying to get out of the game.
