"Fuck it. We'll make a comeback. They're waiting for something huge. Well, give it to them"
This reminds of Memento.
Tenet and Memento are very similar movies as both movies evolve around the same subjects: "implication and perspective"...or rather, "the implication of perspective".
Memento interprets utilizing a non-chronological structure where two perspectives unfold to collide with each other, while tenet's construction involves actual time manipulation, the resulting cinema is intriguing, convoluted and begging for a rewatch !
