Season 2 Episode 8
Well at the end of the second season I still don't know why Hanna was so loyal to and protective of Clara. Clara was mostly a self absorbed bitch.
And in the last episode when they were cornered in that house Clara sent the house sitter hostage guy outside knowing he would be killed. That was cold blooded murder. Yes he got the girl to trip the alarm but from his point of view it was a totally reasonable and justifiable thing to do and he didn't deserve to be killed for it.
