The winter premiere of "The Blacklist" featured Red in a state we've never seen him before - no mercy. Everyone and anyone connected to the Anslo Garrick attack was killed, even his right hand man Newton Phillips.

However, as Red told Liz at the end of last week's episode, there is still an issue in the FBI. Someone there gave Red over to Garrick and company.

According to a clip provided to TVGuide.com, Red is going to find that person in next week's episode. The preview feature's the announcement "Red Finally Finds The Mole". You can watch the video here.

Another sneak peek of the episode shows the next Blacklister does favors for other Blacklisters. Actually he does one really big favor.

As the preview below shows, The Alchemist makes Blacklisters disappear by faking their deaths. What makes his job even worse is that he kills innocent people to do it.

In a recent interview with the Wall Street Journal, show creator Jon Bokenkamp said fans are going to get answers about one of the biggest mysteries of the show - Tom.

"I will tell you that we are going to start exploring him a little more closely," he told WSJ's Jason Evans. "We are going to have some answers about Tom and Liz coming up. That's not a story we are going to be putting on the back burner."

The only thing we know about Tom is that Red doesn't trust him and he may be connected to Gina Zanetakos. It will be good to get some much awaited answers.

"The Blacklist" airs on Mondays at 10/9c on NBC.
