For what it’s worth, I put like 2-3 additional AI lines into v3 before watching it with the others. And even then, when I outright asked them what lines seemed off, they said that Poe’s mouth movement was off and that Kylo’s line at the beginning seemed new because it mentioned a clone.
That was it.
Neither of them had seen the movie since it first came out and purposely forgot a lot of it. So essentially first-timers.
