Fred Johnson: "The Belt needs a born Belter to be its voice."
Anderson Dawes: "Once a thing is written, im fo sémpere! it is forever."
Looking back at the OPA conclave meeting in S2E7, which is a nice companion scene to the round table negotiations in S6E6.
Ty Frank mentioned that everyone here learned their lesson by the end of S6:
Ty: "And I'll just say this for our audience, here's a little Easter egg for you guys: The things that happen in this scene in this episode lay the groundwork for one of the most important scenes of season six. All the people who are here learned their lessons and those lessons play out in dramatic fashion at an incredibly important moment in season six so we're playing the long game."
It seems that Holden did learn the lesson that Fred Johnson first demonstrates here, and that pays off most notably in Holden's decisions in the finale.
In the conclave meeting, Drummer remains in the background and does not even say a word but the camera never forgets her. The framing is interesting as it slowly pans to reveal Drummer behind and in the blur, when it could have just stayed within the shot of Dawes with Fred. I doubt it is foreshadowing, it seems rather early in the show's production for that, but I really love how even then there is so much attention to detail in these scenes.
Drummer silently supports Fred as he endorses Anderson Dawes, whom she is wary of, having left Dawes to join Fred. And when Holden butts in to support Fred, he gets her attention.
Dawes says Holden is an idealist but everything that the Belters have done was not even enough in the end to gain a real footing and equal voice among Sol's powers. Not even what Marco Inaros did could give them that. In the end it still took someone like Holden, an idealist, to give the Belt real power.
