>>53707983As long as the subject of liking Ash never, ever came up, it wouldn't be out of character for Misty to really like Serena a lot. She's usually gets along with girls her own age, wallflower types especially, she loves cute romantic stuff in spite of her brusque confrontational attitude and even nerds out for Paris specifically.
But it would be very out of character for her to not give a shit about another girl trying to woo Ash.
