>>54636975>Are there ever any episodes after Johto that have callbacks to gen1 or gen2 stuff? Yes
>Do they ever run into old gym leaders, or even random trainers like the bugcatcher in Viridian Forest, or that anime-only gym leader with the Sandshrew?Yes
>Does Ash ever meet/battle Giovanni?Yes
>Do all the Elite Four from gen1 or gen2 show up?Not Will and Karen, but all the others
>And how many episodes before the finale do I need to start watching fromIf you're just going to watch for muh continuity, don't bother. If you're not going to watch the show for the fucking show and just for the ebin 25 year long story, there's nothing in here for you. As
