There's nothing like a juicy origin story to get at the heart of a character. Last week, the show delved more into Cara's past and this time it was John's turn - and what a past it was.

I had wondered how a guy like John could ever have ended up in Ultra and this episode gave me my answer: He was recruited young. Not only was he recruited young, but he was taken out of a horrible family life. It was a strange thing to realize that Jedikiah had actually given John a better life than the one he had before he became a part of Ultra.

Finding out that little John used to go out and steal to keep his foster brothers and sisters fed came as no surprise. In fact it made a lot of sense when you think about how he is with the people that are under his care. John has basically been caring for people ever since he was a child, which is kind of sad when you think about it.

John didn't only gain a father-figure when Jedikiah brought him into Ultra, he gained another brother. Killian was someone for John to look up to, but luckily that admiration didn't extend too far, at least not to the point where John had become a heartless man who killed innocents to make his point.

But become a killer he did and that was perhaps the biggest shocker in this episode. Even with the all the double-crossing back and forth between Jedikiah, John and Killian. Everyone was trying to trap everyone, but in the end John did what Jedikiah wanted him to do. I knew that Killian had been "fixed" so that he could overcome that hurdle, but I hadn't realized that John had, too.

Now that John has revealed that he can not only kill, but is willing to kill someone who was like a brother to him, it raised a lot of questions in my mind. What will it take for John to feel as though he might need to kill again and just who could be at the end of that attack the next time it occurs? Or was this simply a very rare event that will haunt him for a long time to come?
