I watched your video and like it MR.
It’s really clean and fits with the “seriousness” of what’s going on with the situation
I mean, the way I always interpreted it is that he knows Zorri would never actually shoot him. They had a thing going for a while there and he probably believes she’s just venting her frustrations at him.
Furthermore, I personally feel like it’s a good idea to try to make the audience feel a bit better after the last portion of the movie “killed off” a beloved character. Sure, maybe it isn’t right for the trio to be acting that upbeat but it might be what the audience needs to keep them invested until Chewie is revealed to still be alive.
Would be interested to see what Hal has to say about this, though.
