I mean, even if it is an alternate universe, we know travel between them is already possible with the Mirror World and Alternate World. They can just have Ash fall through a portal or something and send him back once his role is done.
You're right. I'm getting ahead of myself. They'll probably get back together next episode considering it's a direct continuation of this one. Still, it wasn't a good feeling watching them walk away like that.
With the fake-outs they're doing with Ash and Pikachu, I get the feeling that the last episode will have Pikachu thinks Ash is doing a fake-out but Ash ends up going with his original choice. Maybe in the last battle (possibly with Latias), Pikachu thinks Ash won't pick him, but Ash actually does.
I liked most them though. Except for Tri and Sevens, which funnily enough are the latest ones I think.
edit: Okay apparently there's a new Digimon series. So I haven't watched that one yet. Or know anything about its existence until now...
Haha. That's true. But I meant both of their storylines. Although I can see the potential to stretch them out, they feel better suited for a singular (Paldea) series than presumably long-spanning like Ash's.
While I genuinely love Charizard, Infernape and Incineroar. I'm pretty sure having three fire types on a single team would be bad for Ash given that Leon could probably take them out/deal heavy damage with Inteleon alone.
