I agree with Broadbeck7 that having the A and B plot changing less frequently would work better between Boba and Mando in Book 2, and also make it easier to find those connective tissue scenes because you’d have to find less of them.
As for the Boba/Din scene no going after the armor conundrum, I was at first thinking something along the lines of EddieDean’s, but Mando doesn’t have his ship so he can’t do that. How about voice-overing something when Boba is looking at Mando (there has to be something you can use): “Not yet.” Or “Too far.” Or something to indicate the reason he isn’t going after him yet. And then his body language sells the rest.
