I just don’t understand why the dialogue needs to be gutted though, in my opinion it’s much better the way it is originally. I don’t think it works to splice the Crait line before “maybe it is”, it breaks the flow of the conversation, and I don’t get why you’d remove “Everyone’s so afraid. They’ve given up”. This doesn’t contradict Poe’s development from TLJ, and is integral to his arc: Poe still believes the Resistance is the spark, but he laments so many people haven’t joined the Resistance because they’re afraid/given up. When Zorii says “there’s more of us” she’s telling him there are more good people in the galaxy, good people who’d be willing to fight. This is something he still believes (which is why she tells him “I don’t believe you believe that”), he just has moments of doubt, such as this, the scene on Leia’s death bed, and the ‘lowest point’ of the battle on Exegol.

Poe’s arc in this movie goes hand in hand with it’s main theme: he goes from believing the Resistance has to fight alone, to putting his faith in the people, The people who come together and (in this version) Rise in the name of Skywalker. He basically goes from only focusing on the spark, to actually letting it light the fire that brings the First Order down. Poe’s conversation with Zorii is a key moment for the story and his character arc, and is one of the few legit callbacks to TLJ. I don’t think it’s a disposable, meaningless moment… and I don’t think it should be tampered with.

We can add signs of rebellion on Kijimi without interfering with this, in fact it could heighten the fact Poe is so focused on the struggles of the Resistance he’s (partially) blind to signs of the external growing uprising. Maybe the moment he listens to rebellious calls could work, if it can be done seamlessly, as the moment he regains his hope/faith in the people, but I think the previous dialogue with Zorii shouldn’t be altered.
