I don’t think it is an insult to her character, but beyond that I have to agree with Dr. K, though. I think it would be of a benefit to omit that line for the reasons he previously mentioned. It would actually feel like the First Order is invading various parts of the galaxy, like the crawl mentioned, if Maz is off somewhere else also fighting them. The last time we see Maz, her home and livelihood was destroyed by the First Order, and she even says that “we” must fight them. Plus, if she is going to be with the Resistance in IX, wouldn’t it make sense to have Maz already be fighting the First Order?
I personally didn’t think the “union dispute” was sarcasm. Maybe it was meant to be, but I don’t think think it came off as sarcasm to most people if you were to ask them. Just my guess though. I think if you heard something like Stormtrooper blaster sounds or chatter through the hologram it would probably help get that idea across.
Sorry poppa, I know this discussion isn’t directly related to your edit.
