In "The Blacklist" season 4, episode 4, Liz and Tom become more and more desperate to find Agnes as their daughter might not live for long.

The previous episode for "The Blacklist" season 4 has everyone finding out that Alexander Kirk might just use some virus to prolong his life. With this revelation also comes the possibility that using the blood of a kin could help him survive his illness.

This is the predicament Liz, Tom and Red will have to face coming into "The Blacklist" season 4, episode 4. There might be a chance that Agnes' life will be in much more danger than it already is with the fact that Kirk could endanger her to save his own life from imminent death.

According to CarterMatt, the team will have to track down an eco-terrorist who has ties with Kirk in the hopes to finally find baby Agnes. Will the task force be successful this time? It would seem from the video promo that their lead might be a dead end once more.

This may also cause Tom to go rogue in the hopes of getting Agnes back on his own terms. The teaser for the next episode entitled "Gaia" has shown Tom and Liz arguing. This argument might be an aftereffect of Tom's decision.

In addition, Tom is seen leading a small army of men in raiding a home. This is definitely an indication that the devastated father will do things his way this time around.

In other promos for "The Blacklist" season 4, episode 4, it appears that people's fears are not found unjustified. Kirk is seen being injected with what looks like a temporary cure for his illness. At the same time, the doctor looking after him makes a comment about how they could try using Agnes to cure him.

It is unclear whether Kirk will really use Agnes to save himself but by looking at the promos and how this season is panning out, Kirk may just hold off on the suggestion, for now.
