In the episode four of "The Blacklist," "The Stewmaker," Liz (Megan Boone) would have dissolved in a chemical concoction if Red (James Spader) had not saved her on time. Red pushed the stewmaker in the same tub of chemicals that he had prepared for Liz to disappear, permanently without any residue of her body's existence. Liz called Red a monster for doing that.

It looks like Red has his own personal reason why he pushed the stewmaker in the tub and did not let FBI handle him.

The stewmaker had the habit of clicking the pictures of his victims before dissolving them in the bathtub. From the album of the victims, Red took out a picture of a young girl before giving the album over to the FBI. How is the girl related to Red? It is a mystery to solve for another day, like the biggest mystery of all why did Red chose Liz. Also, for a fleeting second, we saw Red caress Liz's hair -- when she was unconscious -- like someone who really cares. That fleeting second added a new dimension to the character of Red.

The mystery behind Liz's husband, Tom (Ryan Eggold), is getting deeper. In the episode, Tom acted like a sweet, understanding husband, while Liz was trying to dig out information on Angel Station. The man is hiding more than a gun, fake passports and money as his weekend getaway idea was taking her to Angel Station hotel. Angel Station is the key to resolving another mystery in this NBC's new drama series.

"She is so madly in love with her husband and devastated by the cruel world she is being introduced to. It's a tumultuous journey for her. In her case, it's a story of a young woman coming into her own," Boone said to Today Entertainment.

We wonder if there is a possibility of Donald (Diego Klattenhoff) and Liz relationship developing into something more than a cold, professional FBI colleague relationship. After the near death experience, Liz had a breakdown and Donald provided his shoulder and calmed her down.

"The Blacklist" is full of mysteries and each character looks like has his/her own mystery box. The dissolving of victims in a pool of chemicals reminded of "Breaking Bad" and Walter White. "The Blacklist" is riveting and holds the attention and it has the potential to become hugely popular like the cult drama series "Breaking Bad," which wrapped-up in September.
