>>22866945Brock was still kind of the older brother of the group. He cooked the meals, he took care of sick pokemon, etc. I agree he didn't have much to do but at least they got a couple really important notes right, like his farewell with Ash.
And at least he isn't like XY TRio a lot of the time where he sucks up time in an episode with literally nothing to contribute. His flirting gag can get old but at least it can get a chuckle out because it's different based on what girl he's flirting with.
