Well we already beat Blake, it would be kind of weird to have beaten the Champion before, right? Using your deduction system that would make it Arclight, Anna, Lin, Heather and Gossip Gardevoir.
GG seems wierd, as well, she's a Pokemon and we've already beaten her.
Arclight has a story line? I've only met him once at the club, never seen him after that, still waiting for him in 7th Street.
Heather, being raised very restricted by Corey seems like a weird plothole to me (sure, she has a Salamence and ability to Fly, yet she officially wasn't able to beat Corey's Crobat(Champ level Salamence should be able to 1hko a level 30 Crobat. Actually any Salamence should, since it evolves at level 50, c'mon). When, between being constantly watched by Corey, getting stuck in the Orphanage, and getting "adopted"(locked up) by Blake would she have time to become the Champion?
Anna and Lin still make the most popular options, but I'm honestly hoping for a complete plottwist later on that no one sees coming.
Btw How's Laura doing? Where'd she go? And I think her ass just got done replaced by Bennett, but also just speculating...
Thanks!! That is one awesome map.
