Um, what was the point of this episode? Are the writers trying to make Ronaldo even less popular than Lars? After Ronaldo is given a reality check in his hunt for “rock people” (since Steven is half-rock), Ronaldo wants to become a Crystal Gem himself. Steven tries to humor him, but Ronaldo spends most of the episode telling Steven how he is doing things wrong.
So yes, Ronaldo is a self-absorbed (take your pick of two words that rhyme with brick). This was just an awkward episode from start to finish. It is in Steven’s nature to see the best in everyone including people like Lars and Ronaldo. And yes, Steven has lashed out at Lars before (“Lars and the Cool Kids”) and does the same here with Ronaldo. Yet, they are still jerks and Ronaldo is doubly so here. Ronaldo calls himself “Jerknaldo” towards the end of the episode after the way he treated Steven, but you would be justified if you yelled at your TV or digital device, “THANKS, CAPTAIN OBVIOUS!”
This was simply a terrible episode featuring an uninteresting character who comes off as even more of a jerk than he was previously.
