The discussion of Batuu reminds me of how very surprised I was that they DIDN’T crowbar in a reference to Batuu- in particular, I was expecting an off-handed reference to having gotten help repairing the Skywalker lightsaber at Savi’s. There’s a couple of random references to Batuu in Solo, which was interesting.
Though, given that we know there were originally plans for an ongoing plot about Rey building her own saber across the movie and that, at the very least, earlier drafts of the script (and the visual dictionary) tied Rey learning to heal with her healing the Skywalker Kyber crystal, I understand why they didn’t, in this case.
