Present Yo-Yo will have to try and interpret her words to stop the world from ending, and Mack will have to deal with the trauma of watching future Yo-Yo murdered by Kasius.
On a desperate mission to find and save Inhumans before Kasius could harm them anymore, Yo-Yo came across somebody she didn’t expect: a future version of herself.
She had been killed and reanimated over and over again so Kasius could take her blood to create new Inhumans, which resulted in both of her arms being amputated.
