"The 100" season 4 episode 3, titled "The Four Horsemen," brings new problems and possible solutions, beautiful character highlights, and more than one huge revelation.

According to a synopsis published on Spoiler TV, the upcoming episode of "The 100" is about Jaha (Isaiah Washington) leading Clarke (Eliza Taylor) and Bellamy (Bob Morley) down a road to possible salvation. Meanwhile, tensions rise in Arkadia and Polis.

In "The 100" season 4 episode 2, titled "Heavy Lies the Crown," the Arkadians found a glimmer of hope that may ensure their survival in the form of a hydro generator. When the retrieval mission took an unexpected turn, Bellamy chose to liberate a group of prisoners, and he blew up the hydro generator. Because of this, Raven's (Lindsey Morgan) fragile survival plan completely fell apart.

If the previous episode is about choices, this season's episode 3 is about the consequences of those choices, according to Hypable. The characters will have to deal with the fallout of Bellamy and Clarke's divisive decisions.

Based on the promo released by The CW for "The 100" season 4 episode 3, Clarke and Bellamy will be facing a huge hurdle as several members of the Sky People are beginning to show signs of acute radiation sickness. This means that their current base will soon feel the full-blown aftereffects of the nuclear power plant meltdown, and they only have two months to find a fallout shelter that can protect them from radiation.

Running out of options, Bellamy and Clarke receive a dangerous proposition from Jaha — to evacuate and find the fallout shelters before it's too late. However, this mission also opens them to many risks, especially since the people of Polis may attack their group at any time.

However, their actions are not the only ones that have inescapable consequences. In the coming episode, Raven, Octavia (Marie Avgeropoulos), and Murphy (Richard Harmon) also stand to deal with their own respective moments of reckoning.

"The 100" season 4 episode 3 airs on Wednesday, Feb. 15, at 9 p.m. EST on The CW.
