I like the idea of introducing changelings, and that one of the main characters being revealed as a changeling would be a brilliant twist.

A note on the plurality of the title. It could still refer to a single cast member, since the Human Child and the Fairy replacement could both be considered changelings. Although, there could also be a society of the humans that had been changed out, and that community could also reference the plural changelings.

Some thoughts on how this could play out.

1. Robyn and Neal were both left in the care of the Fairies when the rest of the gang left for the underworld. That would be an easy way for the fairies to swap them out, should it actually be the fairies responsible. somehow either Zelena, Snow, or both notice some startling behavior in their children. This could also be a way to introduce a short arc to deal with the Black Fairy.

2. Zelena could be a changeling, despite the blood magic tie. she was abandoned alone in the woods, and it would have been easy to swap her out with a magical child (which could also go a long way to explaining why she is so powerful in magic). and we don't know all of the limits of Fairy Magic, so maybe Fairy Magic is capable of breaking even Blood Magic.

3. Belle, as some have mentioned could be a changeling, or that could also have been her mother Collette. In either case, that would put Belle as having Fairy blood at the least. Could make for an interesting reveal, particularly in Belle's current condition.
