SpoilerDuring Tiger and Barnaby's confrontation with Ouroboros, Jake accidentally shoots down the escape helicopter she is piloting, causing her to fall out onto the stadium roof. After the conflict, she falls into a coma and is hospitalized, her head shaved to prevent her from using her powers should she awaken. Ten months later, Kriem comes out of her coma, only to reveal that Jake had kidnapped her on the day that Barnaby's parents were murdered.
Kriem was harassed by people for being a NEXT throughout her childhood, which made her feel worthless and inferior to humans. When she was kidnapped by Jake, her parents, ashamed and afraid of their daughter, did not bring the ransom. Urging Jake to kill her and end her worthless life, Jake instead taught her that she was superior to humans and that they only ostracized her because they were afraid of her. From that day on, she joined Jake in the fight to create a world where only NEXT existed. Upon revealing her past, she rips out the IVs keeping her alive, telling Barnaby that he would live the rest of his life in doubt as punishment for killing Jake before dying. She also reveals in her final moments that Jake only controlled a small portion of Ouroboros, and the organization is far bigger than anyone could comprehend.
