Fast & Furious 8: What The Ending Of Fate Of The Furious Really Means
6. Cipher Lives...
During the climactic battle, Cipher manages to escape her own plane as Deckard Shaw breaks into her control room, taking the only parachute (which she magics out of literally nowhere) and presumably not landing in the middle of the frozen Russian ocean.
This is absolutely not the last we will see of her. She really doesn't seem like the kind of person to let things lie - in fact, most of her story arc here is based on the fact that Dom and his crew ruined two of her plans. She's not going to suddenly retire because he did it again.
At one point, it actually really looked like it was going to be revealed that Cipher was Mr Nobody's daughter, given the so-very-obvious ghosts in her past relating to family. But that itch hasn't been fully scratched yet, so all we were left with was the questions of why she felt familial betrayal so poignantly.
Could that be a revelation for the next film?
