Let's be frank: The Blacklist Season 1 Episode 12 wasn't the strongest installment of the series.

This was partly based on a lack of Red Reddington, but also based on a couple of very entertaining hours over the past few weeks. There's always bound to be a letdown on any series.

Overall, The Alchemist was an interesting idea for a character. He protects the guilty? So he can turn these people into entirely different folks via genetic manipulation and hide them from being located? Pretty cool.

But there wasn't a ton of charisma involved, making him into a rather generic individual unfortunately.

There was one major reveal, however. We finally learned the identity of the mole, a secret that came out toward the end of the hour. Who is it?
