Yes! It's finally over! Turns out Mim's powerful evil witch mother Esmerei was the one behind everything! She had lots of people under her control, including her own daughter Mim and even Yen Sid! Esmerei made Mim's life miserable from the beginning so that Mim would become evil and delve too deep into the black magic, so then Esmerei could possess her own daughter to take over the world! How sick and twisted is that!?!? After she left Mim's body, Mim was very weak and dying, but Dad encouraged her and she pulled through and helped us defeat Esmerei! Yen Sid used his magic to help us fix the town and now everything's back to normal, and Dad's spirit isn't going to fade!
And the most surprising part is Mim has turned good and she and Merlin are together again!
