deltarune
Aw geez. I just realised King Dad reflects some of Bad Susie's mannerisms (even repeating one of her lines, word for word)
And like, I think it's a stretch to say this is canon, but you know my opinion that Susie is the actual protagonist of DELTARUNE.
And like, what if that entire character was metaphor for her overcoming her guarded, antisocial tendencies and reconnecting with the part of her that can make friends and trust other people (Lancer?)
