First I had some really second thought if to watch this serie but for episodes like this, it shows that this serie has so much to offer. They have great characters and the story, motion... It really catches the eye and you just cannot notice when those 42 minutes pass. And when it is over, you cannot wait for another episode.
What this episode has special? I think this episode is somehow turn point - when season started with big boom, then got some slow tunes and then started to build the heat, then now everything explodes. And not only literally.
So, this is most episode - and get ready as after this, you just have to see the season finale!
