(Another slightly off topic post)
What we are seeing is a power struggle in another universe, the mirror world. The key to the power struggle – which could be between a) the Queen, the Prince and their cohorts and b) the Resistance, fronted by Finnegan, perhaps the original Puppet, perhaps Pinman etc – is one person from our world, i.e. Sam.
The struggle begun ages ago when the siblings – toymaker sister and prince brother, who incidentally were not nice persons at all – found out that they were, in fact, siblings. This they found out when she was commissioned to make him a puppet.
Through magic means (I think the magpie is sort of the fairy of this tale, granting wishes or making things happen) the toymaker is given the opportunity to bring the puppet to life. Still, bad person as she is, she tries to trick the magic. She ends up in the Mirror World, and finds that some of the things she has brought there – items and skills – give her power over the things residing there. At last she has a chance to be a queen in her own right! Eager to bring her brother along and rule this domain together, she struggles to find a way to do so. She realizes the only way is to bring him through the mirror, which she manages to do.
The original people of the mirror world take up the fight against the Queen, who manufactures armies. But the longer she’s in the other world, the more diminished her powers become. What she would need to finish the fight is the powers of one special person in the real world – Sam.
The Queen tries to ensnare her by her love of her brother. But, even though she made the promise, Sam recoils and runs from the fate she sees beckoning. The Queen is furious and traps her unfortunate Brother in the body of a magpie, but doing it so clumsily she left parts of him out, like the voice Pinman now has – perhaps mocking the original magpie, perhaps “on top of” the original magpie’s personality? – until she’ll get a chance to get her hands on Sam again.
Now, the Resistance is in trouble, as the Queens armies are overwhelming them. They see that the only way to get to the queen is through Sam, so they arrange, through the first puppet and through Finnegan, to have her transported into the mirror world. One last throw of the dice, so to speak. The mirror-Sam is a doll who became alive when she entered the real world. She’s not evil per say, just to keep Sam on the right track, worrying about her family.
Incidentally, I think Badger is the one who will turn out to be a traitor in the Resistance. Never quite trusted that fellow, much too quiet.
So – evil people are the Queen, the Prince and their cohorts. Good people are Finnegan, Pinman, the original Puppet, the magpie, mirror-Sam. I think the whispering voice could be the original Puppet, driving her along, trying to get her on the right track.
So now, just get rid of the evil people, get Sam back, wrap things up?
