Man, that's real bad if no one knows what Reva was doing in the finale. That was one of the major plot points.
I can only say that neither I nor my wife understood Reva‘s actions in the finale.It's been explained previously in the thread so I'm not going to go over it again but I knew exactly what and why Reva was doing what she was doing. There's no scene where someone delivers exposition to explain it but it's certainly not hard to figure out. Unfortunately, it seems like modern movies/shows have trained audiences to require an explanation for everything and if it's not there, they complain about "plot holes" when they could easily figure it out themselves.
And Obi was not a subtle show. This is the show where Obi walks out with a girl laughably half-hidden under his cloak, while the Empire’s best and brightness don’t see it. Everything was telegraphed and made explicit. For it to suddenly become nuanced and hint-hint about major character motives is not what this show was doing.
