Something wrong with the team you mean? It wasn't just made up of Hyuga. That's what she analyzed not that he betrayed the Hyuga Clan.
Just saying she didn't have the most brave portrayal between that and the tunnel which made the fight with Taiyo and personality in said fight jarring (Which I commented at the time and we talked over then if I recall correctly).
Contrary to what you and Shen seem to believe, she's not cowardly. And what I was implying was that based on the information available to her it seemed like her friends and family had been in danger and Kai might've betrayed them.
Being out on a mission alone for the first time why would she choose to fight both Tayuya and Kai?
She thought it better to flee the encounter, so she did.
I never said she was brave, but she's, again, not cowardly. She ran from Taiyo because he started yelling at her for what she saw to be no reason. For someone who I was trying to portray as childish, I felt it was an appropriate reaction.
Her fight with Taiyo was fueled by rage and impulse, because she's again, not a coward, but childish.
Edit:
I might be misrepresentating her personality in RP, but even before she was introduced I made it clear childish was what I was going for.
