I think the google dude is obito and he was probably killed during a dangerous mission because of Kakashi thats why Kakashi always curses himself for being stupid back than....and i think that female is Kiba's mom....just look at those lines on her cheeks...if i remember correctly when they show Kiba's dad and Mom fighting you can see they have those marks too like Kiba....hmmm maybe thats why Kakashi has the Dogs too...

and 4th is exactlly like Naruto both have blue eyes and blond hair....amazing similarity....maybe thats one of the reasons they haven't told naruto that 4th was his father...and he gave aways his life to kill kyubi and seal it inside Naruto....otherwise Naruto would hate himself since his father died to kill Kyubi...hmmmm
