Sakura and Ino almost gave away their secret mission to procure a wedding gift for Hinata and Naruto. Their ninja skills in causing a diversion served them well, kind of.
Sakura and Ino successfully kept their secret mission from Hinata, but they needed a little help from their senior Tenten.
Kiba and Shino acted a little suspiciously when talking about the upcoming wedding, enough for even Hinata to notice.
Tsunade was irritated that Kakashi was following that old rule about attending weddings applied during peace time.
Hinata expected her old teacher Iruka to say something nice and profound about Naruto. She was right.
