During the climax of “Fast X,” it appears Aimes finally realizes that Dom and his family have been set up by Dante, and The Agency’s new leader starts helping our heroes as they try to outwit and outlast Dante. But in the end, it’s revealed that Aimes has been on Dante’s side since the events of “Fast Five,” with a retcon flashback revealing Aimes’ presence during that film’s vault heist, sparking a partnership that led to this game-changing twist. The reveal comes when Aimes, the latest antagonistic figure who has seemingly become an ally of the family, uses a rocket launcher to blast a plane with Roman, Tej, Han, and Ramsey out of the sky, sending it crashing into a mountainside. 

Interestingly enough, Ritchson recently revealed to Entertainment Weekly that the connection between Aimes and Dante was almost even more substantial. The actor pulled back the curtain while talking about how much he knew about the character going into production:

“I don’t know if this is divulging too much, but we shot a couple different stories. One was that Jason Momoa’s character and Aimes were blood brothers. They were actually related, and one of the reasons why they were unified was because of their genetic link. There is a version in the editing room of that film, but at the end of the day it was decided that the other version which is what’s in the film now — we learn at the end of the movie that really surprising twist that there was an alliance between them the whole time making him maybe the bad guy — that’s what we’re left with. I wasn’t really sure which version of that was going to live, but I did know that there was a lot of duplicity in the character and that he was ultimately a bad guy, at least for now. We’ll see what the future holds.”
