>>28255805>despite her not seeming to have a strong crush on the MC like Serena or Angie and having a thing for orange island's or celebrities' D, she's jealous of every girl who's flirty with AshSo logically, maybe the answer to her behavior is that she DID have a crush on Ash, eh? There's I think, two Orange League leaders who had a thing for her, and one even wanted her to stay with him on the island (in the manga, asked to marry him), but despite being heavily conflicted, she still decided on sticking together with Ash.
And, heck, those two episodes had ASH, of all people, jealous about Misty's flirting with the Orange leaders. I'm not sure why people here seem to genuinely think it was "dub added", when even the manga touched on it.
Though perhaps it's the long-ass Johto fatigue with the OG trio that made everyone forget the times when they still had character traits, interests beyond the big, loose goals, and weren't so oblivious of romantic feelings and all that. Well, Brock excluded on the last one.
