Season 5

Complete listed story — includes the ending

1. Eden

In a flashback to six weeks after Praimfaya, Clarke searches for food and water in the rover, first going to Polis where she tries to dig out the bunker, then to Arkadia where she finds Maya's MP3 player among other people's possessions as well as Jasper's goggles and a suicide letter addressed to Monty. She then drives to the Dead Zone, where the rover breaks down in a storm. She follows a bird, at one stage considering suicide, and discovers the Shallow Valley. She finds a room of dead people, then a young Nightblood girl who runs from her. Clarke follows her and tries to get acquainted with her, which does not work until Clarke draws a sketch of her. The time jumps back to six years after Praimfaya, where Clarke and the Nightblood, Madi, are living together. Raven and the other six on the Go-Sci Ring try to boost signals to contact the Bunker, when they see the Eligius ship. Clarke watches the passengers debark the ship, where they roam the area and almost kill Madi, before Clarke jumps in. Echo tells Bellamy she is afraid of returning to the ground. Octavia watches over Wonkru warriors fighting to the death.

2. Red Queen

Shortly after Praimfaya, the clan delegates discuss punishment for a thief. Kane and Abby hear Clarke knocking on the bunker, and when they try to open it, they discover it has been sealed shut due to the rubble from Polis. A Skaikru rebel stages a coup and locks several Skaikru members in the farm area. While grounders gather the remaining Skaikru not in the farm area, Jaha is stabbed. Octavia spares him due to his expertise as an engineer. With Jaha, Indra, and Gaia's help, Octavia resolves the problem of opening the farm area door and proves herself to be a capable leader. When many grounders question her leadership, she kills them, telling them they are Wonkru, or they are against Wonkru. Those remaining bow before her. After opening the door, Octavia, Kane, and Abby rush to Jaha's aid. As Kane recites the Skaikru prayer, Jaha dies of his injuries. As punishment for Kara and the guilty Skaikru involved in the coup, Octavia instructs them to fight to the death. Kara emerges victorious. Six years later, Octavia and her advisers watch over Wonkru warriors fighting to the death. The next batch of combatants are brought in, Kane among them.

3. Sleeping Giants

Clarke and Madi hide from the Eligius crew, while Diyoza sends McCreary to find them and interrogate them. He captures Clarke and brings her to Diyoza. To make Clarke talk, she orders Madi shot on sight. Clarke promises to tell her everything. Raven and the others board the Eligius IV ship in space and find a way to Earth. Monty and Murphy argue over returning to Earth, when Echo finds a lab of cryogenically frozen prisoners. One prisoner is remotely woken up by the prisoners on the ground and attacks Bellamy, who kills him. In order to leverage the frozen prisoners against Diyoza, Raven stays behind. Bellamy objects until Raven tells him of an escape pod that she can use to go to Earth. Bellamy, Echo, Monty, Harper and Emori safely make their way back to the ground. Murphy stays behind with Raven and learns that there is no escape pod and they are trapped. The Eligius men find Bellamy and the others. Shortly after, Madi kills the Eligius men and guides them to Clarke. McCreary uses a shock collar on Clarke. Bellamy arrives, telling Diyoza that 283 frozen people will be killed if they do not release Clarke.

4. Pandora's Box

Octavia punishes Kane for stealing medicine, which is a crime against Wonkru. Bellamy and Clarke reunite after he brokers a deal with Diyoza. Diyoza outwardly accepts the deal but still tries to hack into the Eligius mainframe. Bellamy and Clarke, with the help of Diyoza and McCreary, break into the bunker and rescue everyone inside. Octavia is the first to be lifted onto the ground. Miles opens the docking bay doors to Eligius 4 in an attempt to kill Raven and Murphy, but they counter by waking up the frozen prisoners. The Eligius warriors on the ground break the deal and take Kane and Abby. As they attempt to fire missiles at Wonkru, they find that the launch codes have been changed. Miles tells them it must be Raven. They fly to retrieve Raven while Octavia tells Wonkru to prepare for war.

5. Shifting Sands

Diyoza orders Kane and Abby to help and cure Vinson, while Octavia takes her people to march on the Shallow Valley. McCreary tortures Raven and threatens to kill Murphy to find out how to turn their weapons system back on. Miles stops him with a gun to his head and reveals to Raven and Murphy that he was the one who disabled the system. Abby tells Diyoza she does not know if she can help Vinson. Murphy escapes with Miles' help and Echo finds him. She, Murphy, Harper, Emori, Monty and Madi set out to find Bellamy, but McCreary activates Murphy's shock collar, leaving him with Emori while the rest keep on the journey. A Wonkru warrior dies and worms pop out of his chest. Octavia and Wonkru retreat, as the four in the van arrive. Octavia angrily witnesses Bellamy and Echo's reunion, as do a reconciling Madi and Clarke.

6. Exit Wounds

Octavia confronts Bellamy over his relationship with Echo and reiterates the latter's banishment. Diyoza's ship arrives, delivering apples and offering free passage to any Wonkru defectors. Octavia offers Echo a deal to spy on her people and report anyone that plans to defect in exchange for her banishment to be lifted. Echo decides against Octavia's plan, offering instead to go undercover as a defector so that she can hack into Diyoza's camp, with Monty's help. Octavia agrees, but has Cooper shoot fleeing defectors, ostensibly for appearances. Monty eventually deduces that he will need to access the firewall for Diyoza's camp from the inside. Murphy and Emori work to remove his shock collar and decide to use his collar to set up an explosive trap, during which time they discuss and rekindle their relationship. The two find that McCreary survived the explosion and take him hostage. Clarke, believing that Octavia will figure out and kill Madi for her natural Nightblood status, plans to leave with the defectors. Madi objects, fearing for Clarke's safety, and reveals her status to Octavia. Octavia tells Clarke that nothing bad will happen to Madi and that Madi will train as a Wonkru warrior. Echo successfully infiltrates Diyoza's camp.

7. Acceptable Losses

Kane finds Abby huddled on the floor by a dead patient and deduces she was high on pills during the surgery despite her denials. Later, Kane gives Abby an ultimatum; him or the pills. Diyoza interviews the Wonkru defectors to determine their use and trustworthiness. In order to gain Diyoza's trust, Echo reports Shaw as the one to shut down the systems despite Raven's protesting which distracts Diyoza, allowing Echo to install Monty's backdoor into the prisoner's system. A bloodied, collared Shaw later appears in the defector's room. In the bunker, Clarke and Bellamy discover Cooper's human experimentation to breed the parasitic worms as a weapon. Octavia reveals her plan to release the worms with the next group of Defectors. Diyoza reveals her pregnancy to Abby. Madi, at the urging of Clarke and Gaia, initially hides her aptitude in hand-to-hand combat, but drops the charade during a class presentation to Octavia and is designated Octavia's second. Clarke attempts to negotiate a nonviolent settlement of the valley with Diyoza. The only term Diyoza will agree to is Wonkru's unconditional surrender, to which Octavia will never agree. Clarke declares the need to assassinate Octavia.

8. How We Get to Peace

Octavia is ready to prepare for an all-out war against Diyoza which Clarke opposes. Despite perfecting the algae, Monty's request to end the war and forget about the valley is ignored. Monty, sick of the unending violence, resolves to not go with his friends to the valley. Due to Octavia's unwillingness to listen to reason, Clarke and Bellamy decide to sabotage Wonkru's plan to attack the valley. Clarke and Bellamy enlist the help of Indra to sabotage Octavia's plan. They use the worms to kill Cooper, and attempt to make her death look like an accident. At the camp, Diyoza reveals to Kane that she is pregnant while the two discuss their plans for a better world. Raven finds out about Abby's addiction to pills, and feels betrayed when Abby tricks her into creating a device that can cure the lung disease of the Eligius prisoners. Later, Octavia finds Cooper's body, and immediately deduces Cooper was murdered and she reveals to Indra that she had planned to use the worm's eggs on the camp instead of the worms. Octavia arrests Clarke for treason and plans to have her executed. Bellamy and Octavia have dinner where Bellamy uses Monty's algae to poison her food.

9. Sic Semper Tyrannis

Indra announces her intentions to surrender to Diyoza to Wonkru, only to be challenged by Miller for leadership.

In Eden, Murphy successfully starts a civil war by telling McCreary that Diyoza has a cure for the lung disease. A battle breaks out, and McCreary takes over the valley with Diyoza escaping. Raven, Emori, Echo, and Shaw escape while Kane and Murphy stay behind to find Abby and Diyoza. Octavia wakes up and reports Bellamy's betrayal, but Indra secures the room and will not let her leave. Niylah eventually rescues Clarke who goes to kill Octavia. Octavia convinces her that neither of them want Madi to ascend. However, Gaia performs the ascension on Madi; Clarke then shows up and escapes with Madi in the rover. Octavia arrests Bellamy, Indra, and Gaia and sentences them to fight in the arena. Then, behind closed doors, Octavia sheds a tear.
