>>50756459Trying to give a serious answer to this, I think it is due to the mishandling that was given to her in the BW season, she is a very complex character, especially when they return to her past, but she lacked consistency, on the one hand you have the wild girl who was adopted by a village and who fights with Pokemon just for fun, to become under the tutelage of Drayden the strongest Gym Leader in the region for being a prodigy in battles (As an infant she defeated 100 trainers from continuously) but she was miserable being a social outcast, then we have the Iris that Ash met, a girl with a strong character, bossy, and with a tendency to point out the flaws of others without seeing her own, basically a person without a filter Social.
Finally in Journey she returns, and although she retains her childish and problematic attitude to a certain degree, the atmosphere around her has changed, she no longer projects that antagonistic personality, she feels rather playful and with pardon of the expression it feels as if the shrew was tamed.
Now from a technical point of view it is obvious that these character contrasts are due to creative differences, disrespect to the lore of the games, poor writing, different teams working throughout the series, and although all of this has not been planned the sum of all these mistakes creates an effect of development and growth in the character, it's like those cheesy movies where you get a garbage MC at the beginning of the film and by the finale you end up loving him because of his arc of growth and redemption.
