Priya reveals that she is a member of Tenet and the man who inverted her bullets, Russian oligarch Andrei Sator, is communicating with the future. Sator's estranged wife Kat Barton is an art appraiser who authenticated a forged Goya by her friend Arepo, which Sator purchased at auction believing it to be legitimate, later using the situation to blackmail her. To get Kat's help, the Protagonist and Neil try to steal the Goya from Sator's freeport facility at Oslo Airport but are thwarted by two masked men who emerge from either side of a machine. In Mumbai, Priya explains it was a "turnstile", a device that inverts entropy. The two men were the same person, traveling in opposite directions in time. She reveals that Sator's henchmen sabotaged his CIA team but KORD got the artifact, 3/4kg of weapons-grade plutonium-241.
