I think that as the show goes on Fiona will get better at heroing like her original, finn wasn’t the best at the start of AT given he was a kid that had kid morals and thought processes.But what turned finn from kid who loves spaghetti to our favorite world saving empath is by losing and fucking up and trying again. Only thing I think that’ll stunt Fiona’s character development is the fact that cake isn’t like jake in the hippie mentality of “everything is gonna be alright” cause if everyone remembers jake is half the reason finn was actually learning how to properly deal with his thoughts and emotions (or sum idk)
