Tenet || What went down? || Opera Siege

Here is my take on trying to explain what the heck is going on in the opening scenes of Tenet. Reddit was a great resource for discussion and there were a lot of great insights.

Sator used his knowledge to set up a heist to lift the algorithm from the CIA. Having observed The Protagonist’s willingness to sacrifice himself, Tenet( or Future Protagonist) ensures his pill is fake so he can be recruited and continue the chain of events
