|“||Quiet, they take the strongest.||”|
|— Echo to Bellamy [src]|
Throughout the Series
In Coup de Grâce, Bellamy Blake awakens in the Harvest Chamber in a cage next to Echo in Mount Weather. She quickly tells Bellamy, "Quiet. They take the strongest," in Trigedasleng which he doesn't understand. Bellamy asks what she said and Echo realizes he is a Sky Person and spits on him. She then has the alliance explained to her.
Later when Echo is selected for harvesting, Bellamy saves her by rattling his cage aggressively so that he is taken in her place. Echo then watches Bellamy as he is harvested and after Maya comes to rescue Bellamy. While Bellamy fights Sgt. Lovejoy, at one point Echo grabs Lovejoy's arm to prevent him from stabbing Bellamy with a scalpel, allowing Bellamy to choke him to death. After Bellamy's tracking chip is taken from his arm, he places it in his cage and promises Echo that he will come back for her.
In Blood Must Have Blood (Part 1), Bellamy keeps his promise to Echo and returns to free her. Bellamy tells her that there is a Grounder army outside ready to attack and they need to free all the Grounders within Mount Weather. Echo tells all Grounders to be quiet if they wish to be free. After the Grounder Commander agrees to a truce with the Mountain Men, Echo is released along with all of the other Grounders within Mount Weather.
Echo has brown hair with blonde highlights and brown eyes.
Echo appears to be very loyal to her clan. Since she was unaware of the peace between the Grounders and the Sky People, she initially shows disdain for Sky People. After Bellamy returns to free her, she is shown to cooperate with him and agrees to help the Delinquents when he tells her he will be sending them to her for safety.
Bellamy and Echo at the beginning have a hostile relationship, as Echo is unaware The Woods Clan-Sky People Conflict had come to an end and an alliance was formed. When Bellamy barely escapes from being harvested, Echo sees him as an ally and comes to his rescue when a Mount Weather guard attempts to kill him. Bellamy tells Echo he will return for her and he does so, freeing her and the other Grounders.
