I don’t know if Wally would’ve been a good rival for May. It would’ve been a cute precursor to Sawyer, but May needed someone to push her and make her realize her faults as well as her strengths. Drew did that, but I have no idea how Wally could’ve.
I had problems with some of his writing, but by and large he was such a fun rival. Ursula was similar and she was great, too. I didn’t really like Georgia, but Burgundy was hilarious, and I wish she had been given more development.
I also wish the writers didn’t make Miette so nice and friendly after the Poképuff episode, but her and Serena’s dynamic was fun regardless, so I can overlook it. But Amelia was the perfect candidate for a Harley/Ursula-esque rival, and it’s annoying that she was wasted as a COTD. She didn’t even show up at the Master Class, which was disappointing.
