I'm now all caught up. I enjoyed the callback to Cut and his family and the fact that Rex kept in touch with him. That sort of world-building is nice.
I also appreciate the effort they're going through to explain the whole "chain codes" thing, although I think they still have some work to do to make it make sense in the context from the Mandalorian (e.g. when Boba Fett presents his chain code, it appears to be as much a genealogy as a personal identification code, which suggests to me that it may predate the Empire).
