في الخسائر المقبولة Madi has started her training with Wonkru. Clarke advises her to do bad on purpose so that no one will see her as a leadership threat. Madi follows Clarke's advice during the first training, but it is too obvious to Gaia. Gaia tells Madi that she agrees with Clarke's advice but Madi has to be less obvious. She tells Madi that she wants to protect her too because it's her job as Flamekeeper to protect the next commander. She shows Madi the Flame she's been carrying and Madi is fascinated by it. Gaia says she will be faithful to Octavia but that she must ensure the Flame's succession.

They agree to leave Clarke tied up while they initiate their plans for peace. Since no one can listen to them, Indra and Bellamy devise a plan to have Madi become the commander. They would then use Madi to do according to their ideologies and the grounders would listen to Madi because she's a Nightblood. Indra asks her daughter, Gaia, the Flamekeeper to perform the ascension ceremony for Madi. Gaia is reluctant because she made a promise to both Madi and Clarke. Gaia grees to do it only if Madi accepts the flame. Madi doesn't want to take the flame because Clarke wouldn't want that. But Bellamy convinces her to take it, by lying to her that it would be the only way to save Clarke.

So, Bellamy decides to keep Clarke chained until the ceremony is over. after Niylah helped Clarke to get out of the cell Clarke goes into where Octavia and Indra are. She points a gun at Octavia. After a little argument, Octavia convinces Clarke that they're on the same side. They both don't want Madi to become the commander. So, Clarke and Octavia make a deal - Clarke would help Octavia stop the ceremony and Octavia would help Clarke and Madi escape to the valley. By the time they get to Madi's ascension ceremony, Clarke and Octavia find that Madi has already taken the flame and is unconscious waiting for the flame to take over. Octavia orders one of her guards to take Clarke and Madi to the rover. After getting to the rover, the guard tries to shoot them in Octavia's name. But then Madi wakes up and asks him to drop the gun. She recites the lineage, implying that the ceremony worked and she's now a rightful commander. The guard kneels down and calls Madi "Heda!" But then, Clarke shoots the guard and forces Madi into the vehicle against her will.

In The Warriors Will On their way to the valley, Madi insists that she wants to go back to the bunker to help her people but Clarke forces her to stay in the rover. They find that Octavia had kept the worms inside a bottle in the trunk. Clarke drops the bottle, releasing the worms onto the ground.

Upon arriving at the valley, Clarke and Madi are shocked to see McCreary's people killing the defectors. When one of the prisoners is left to bury the dead, Madi and Clarke approach him and force him to tell them what's going on. He explains that McCreary is in charge now and that Diyoza is in hiding. They ask where to find Abby. After that, Madi kills him immediately. Clarke and Madi head to the gas station medical room. They find Abby lying on the floor, unconscious, due to overdosing.

In The Dark Year After finding Abby unconcious, Clarke and Madi start working to resuscitate her. Clarke makes her throw up to reduce the opiates intoxication, regaining consciousness. Just then, McCreary enters the room and wonders how Clarke and Madi got in without being detected by "the eye." Without hesitation, Clarke reveals that Wonkru worked with Raven and Echo to turn off the satellite camera and replace its feed with a video loop. Clarke and McCreary make a deal for him to let her and Madi stay as long as Clarke gets Abby back on her feet to treat McCreary and his people.

Madi disagrees, arguing that they wouldn't be able to live with themselves. After waking up and hearing Clarke's plan, Abby opposes it too. She tells Clarke that McCreary is a horrible, dangerous. But Clarke insists that she and McCreary have to work together because they both want the same thing - to stop Octavia. As Clarke works on opiates detox process for Abby, Abby says that she's not worth saving. She starts telling them what really happened at the bunker during the dark year.After revealing this to Clarke and Madi, Abby starts crying, admitting that it was her fault. She is responsible for what Octavia has become. This gives Madi confidence to defend Octavia in front of Clarke. She tells Clarke that Octavia did what she had to do to save her people. Octavia bore the burden so that her people didn't have to - just like Clarke did at Mount Weather. Clarke is shocked that Madi knows about Mount Weather. Madi then calls out Clarke for pretending to be the hero. She says that the real heroes have always been Octavia, Raven, Bellamy and even Murphy. Madi declares that she is ashamed of Clarke. Clarke tries to justify herself and goes to help Abby treat McCreary and his people.
