This was a great episode - very cleverly plotted and the way the motion was set and thing started to work - it was amazing. I never expected anything like this - the action, the danger and I think maybe the most shocking moment was when we saw Alex taped up. The man has to be crazy - kidnap his own child this way. It was horrible.
And the ending - I really liked it. The music, the way Luka was so helpless to see what was going on and do nothing and then Abby - collapsing before his eyes and he could not do nothing.
Great season ender.
