As with anything, I think there may have been elements of the truth in what Maurice said. Interesting that Maurice (of all people) is the one to quote the show's mantra on Magic.

I agree, though. what REALLY happened? I am still not convinced that Colette is not Helga. They look different, yes. But interesting that Ingrid and Helga are the 2 that vanished, leaving Idunn/Gerda behind. I think that we can presume that Idunn is non-magical, like Anna, and we know that Anna and Ingrid are Snow/Ice magicians.

I will conjecture that Helga (the 3rd Sister) is also magical, which is why Ingrid took her to begin with. However, whatever happened, there was a falling out or fight between these two, and Helga (the better behaved of the 2) captured Ingrid in the Urn, then realizing that Arendelle was not a place for magic users, changed her identity and stayed in the the Enchanted Forest. She hid her status as a magic user, fell in love with a noble (Maurice), and settled down.

During the ogre attack, Colette finally did what she had to do to protect her child, and that was to break out the magic. She defeated the Ogre, helped Maurice block the memory of what happened from Belle's memory, then disappeared. Who knows where she is now?
