New Alolan forms and UBs feels highly likely even if this
isn't an actual leak, honestly. More Z Moves are basically already confirmed since the trailer teased new signature ones for Togedemaru, Mimikyu, and Midday Lycanroc.
But the lines about Lusamine and Hau fit right into something I've been wondering: if these really do happen in an alternate universe, could we be seeing a
For Want of a Nail plot, where a couple minor changes in the past have created a very different present? Like, what if in this universe, Lusamine wasn't infected by Nihilego neurotoxin, and Lillie is a well-adjusted and competent trainer (with a Vulpix as her signature 'mon) who fills the role of the friendly rival that Hau did before? Or what if Guzma's abusive father was even worse here, causing him to utterly snap and become cruel and monstrous instead of sympathetic and redeemable?
What if the reason they've been so vague on plot details is because it's nothing like anything we've seen in past games: one that starts out similar to the Sun and Moon we know, but then goes off the rails due to this timeline's different circumstances?
