Alright so, since its a pain in the dick explaining without a visual, I spent a million years in PS making this shit ass autistm chart.
Basically, there are 5 states that the Pokemon can be in relevant for this. Relearning happens while in states 2 and 4, ie; deposited in a game, but viewing through Home. While in states 1, 2, 4, and 5, the Pokemon's moveset gets wiped and replaced with whatever the Pokemon's moveset is FOR THAT GAME. So if you had Chilling Water on Pex as it went into Home and into SwSh, once it returns to SV, the moveset with Chilling Water returns.
In that one anon's interpretation that relarning happens in state 3, this would render relearning immediately useless, because as soon as it enters states 2 or 4, the moveset it had while in 3 would be wiped anyway. So it necessarily HAS to happen while in 2 or 4. We already know this is the case through prerelease screenshots.
>>53825467>since there's per-game data for each pokemon, it's probably a per-game "tutor" optionThis is the case, yes, the question comes down to the scope of what its able to learn while in states 2 and 4.
Each individual has a txt file of its moveset associated with each game its been in. IF relearning ONLY checks whats in that pokemon's learnset in the respective game (ie SV has only TMs, egg moves, and level up moves, while SwSh has Tutors and TRs as well), then it makes the feature not technically pointless, but extremely underwhelming.
I suspect the relearning feature MAY check against all compatible txt files for whats relearnable. So a Pex in state 4 or 5 can relearn Scald, since that Pex's state 1 and 2 had it. But we dont know how this works yet, its a big question mark.
