Tear Jerker / Tenet

• The expression on Kat's face when they first talk about Sator and the forged Goya drawing in a restaurant. It is the despair of someone who is trapped in a terrible situation: either stay with Sator, or never see Max again.
• Neil's final farewell to the Protagonist. The Protagonist has seen Neil's inverted body in the pit, and Neil figures out that he won't make it. But it doesn't bother him. He calmly restates that "What's happened, happened," and gently tells his friend, "Now let me go." Neil then reveals that he's known the Protagonist's future self for years—because in the future, the Protagonist recruits Neil for Tenet. The look on the Protagonist's face through this can be summed up to a nonverbal "don't go". Neil assures him that he'll have a lot to look forward to in the future. "I'll see you at the beginning, friend!"
• The fact that in the end, the trust phrases "We live in a twilight world" "and there are no friends at dusk" gain a more real meaning. Ives leaves with a third of the Algorithm to give the Protagonist and Neil a Mercy Lead to make sure the future antagonists never get it back. Neil himself goes to invert himself one last time to save the Protagonist in the hypocenter cavern. Kat is finally able to raise her son in peace, though some people see her as a loose end. Priya tries to have Kat assassinated, only for the Protagonist to arrive in time to thwart the attempt and kill his "boss". The Protagonist watches Kat and Max walk home from afar...from his vantage of the twilight world of espionage, with no friends at dusk. What eases the weight is the knowledge that the Protagonist will eventually recruit a younger Neil into Tenet for further operations against the antagonists.
