Ok, this one was a second different kind of episode in row and to be honest, this one was very weak, at least in story side. The main amount of time was given to Carrera and her past relationship to make some kind of sense out of it, constantly suspecting each other and shouting on each other - in one word, relationship gone bad. I do not know why they needed it but it did looked like a way to fill out the time in this episode.
And the ending, it was kind a weak too. The only possible one you could imagine and if they were going that way, maybe more tragic would have been good.
