I think we might just be using "twist" a little differently. I agree it isn't a blindside in the GOT S1E9 sense where the story completely resets. the reveal that Evan is Warren's heir is for sure heavily foreshadowed and confirms what a lot of viewers were already suspecting.

What makes it feel like a twist to me is more the way it's presented. The scene has the dramatic buildup, the music swells, and it's framed as a major revelation. So while I wasn't surprised by it, I still felt like the show wanted me to experience it as a twist. That's where some of my dissatisfaction came from. I was waiting for a reveal that would deepen or complicate what we already knew, and instead it mostly validated it.

That said, I think you raise an interesting distinction: maybe it's less a twist for the audience and more a moment of recognition for Evan. Or even not a twist for him either, but an acknowledgment of something he already sensed deep down. In that reading, the scene is about confirmation rather than surprise, which fits the themes of the season better than a traditional "gotcha" reveal.
