🔀 Best plot twist that actually caught you off guard this year

Watched a show recently that genuinely managed to catch me completely off guard with a fairly major plot twist about two thirds through its current season, something that in hindsight was actually properly seeded throughout several earlier episodes, but that I genuinely did not see coming at all myself until the actual specific reveal itself happened on screen. What made it work so effectively, I think, was that it was not relying purely on shock value for its own sake, the actual twist itself genuinely recontextualized several earlier specific scenes in a way that made complete narrative sense looking back on it properly, rather than feeling like a cheap, unearned surprise simply inserted purely for dramatic effect. Discussed this specific reveal with a couple of friends who watched it around roughly the same general time as I did, and interestingly one of them had actually correctly guessed it several episodes earlier based on a fairly small specific detail neither I nor our other friend had actually noticed or registered ourselves at the time, which honestly made me want to immediately go back and rewatch those earlier specific episodes with properly fresh eyes. This got me thinking about how genuinely rare a truly effective plot twist actually is these days, so much modern television seems to actively lean into predictable twists specifically because audiences have generally become considerably more sophisticated at anticipating common, well worn narrative patterns and structures used across most shows now. The specific shows that genuinely manage to still surprise experienced, attentive viewers properly seem to do it by actually respecting the audience's intelligence throughout, planting real, genuine clues rather than pure red herrings, so the eventual actual reveal feels earned rather than simply arbitrary or unearned when it finally happens on screen. What is the best specific plot twist that has actually genuinely caught you off guard this year, and did it hold up properly on an actual rewatch once you already knew exactly what was coming the second time through?

A twist near the end of a thriller I watched last month made me pause the episode and rewatch the previous one immediately, something that had not happened to me in years of watching this kind of show regularly on my own. A small early detail suddenly meant something completely different once the full picture properly came into view near the very end.
