We get a surprising amount of growth for Morty this episode. Not only is he more confident with Rick at the beginning of the episode, which we’ve seen as a growing theme throughout the seasons, but he’s even ready to directly challenge Rick. For the first time ever, we see Morty in his full capacity, not just when his good and bad sides are separated, actually growing past Jessica.
