Yeah, the Zori stuff in general is weird. I wish it was more of Poe who was convincing Zori that there are “more of us”, rather than Poe being so hopeless. But, I guess it is sort of necessary for his arc. But he even gives up at the battle of Exegol basically. Everyone is begging Poe to tell them what they should do, and he basically says, “Well, I guess we’re all gonna die now…” I guess it isn’t bad, just wished they would’ve expressed Poe’s growth as a leader in a different way.
I read it more that he goes on an arc to being a good leader and that final moment of despair is the film giving us a momentary fake-out before the big payoff.
I agree, it would make more sense for Zorii to say “You don’t believe that,” then it sounds like she’s telling Poe something he’s told her, but is clearly doubting.
