I'm one of these players who would like Snow to return, and I was thinking of possible ways that she could come back to life. As a kid, I was an avid reader of fairy tales and mythology, and I've tried to remember if there were instances of resurrection after a beheading in Grimm's Fairy Tales.
And it just struck me right now.
Such a case actually occurs in the original fairy tale of Trusty John as collected by the Brothers Grimm (Der treue Johannes).
For those of you who don't already know this tale, you might want to read it here, I'll just quote the part where such a post-beheading resurrection happens :
"If you cut off with your own hand the heads of your two children, and smear me with their blood, I shall come back to life." The King was aghast when he heard that he had himself to put his children to death; but when he thought of Trusty John's fidelity, and how he had even died for him, he drew his sword, and with his own hand cut the heads off his children. And when he had smeared the stone with their blood, life came back, and Trusty John stood once more safe and sound before him. He spake to the King: "Your loyalty shall be rewarded," and taking up the heads of the children, he placed them on their bodies, smeared the wounds with their blood, and in a minute they were all right again and jumping about as if nothing had happened.
I'm new with the Fables comics, but I've read enough to know that Trusty John is the doorman to the Woodland Luxury Apartments, so he will most certainly be a character that we are bound to meet, and he has to live somewhere in the place.
Could it be that he possesses the power to reattach heads and resurrect people, like in his fairy tale ?
(Oh and another interesting point from Trusty John's tale :
Although the expression "these lips are sealed" per se is never used in any version of the tale I have heard of, he too has to keep secrets he can't reveal (The secrets told by the ravens if you have read the tale) even to the King he so faithfully serves, because if and when he does, he turns into stone.)
