I recently posted this on a discussion, and decided to make it it's own. Below is the very comment and theory I contributed:
I like to call this little one 'The Magic Mirror Theory'.
'These lips are sealed.' It is said twice in Episode 1, once by Faith, and again by the magic mirror (when asked to show Faith). If Faith isn't really dead and the there is an explanation for the head, this is more to go on than you may think. The Magic Mirror obviously knows something about Faith or has a close relation to her (likely the former). If this is indeed the case, the Magic Mirror has either knowledge of Faith's "death" and whereabouts and wishes not to tell, or some magic is preventing him from doing so. Again, I suspect the former for a number of reasons. When he says '...these lips are sealed.', he has a sort of grin on his face - he knows, and is not telling. And not because he isn't allowed to; because he doesn't want to. He is voluntarily involved in it or plays a more major than minor role in it. Of course, he cannot be the killer, because he's a mirror. But think. He is a Magic Mirror. If he IS playing a role in this, he is a huge aid to the walking culprits. He has the mans, and most certainly the time, to tell them exactly where the people are and what they are doing; what more could a murderer/kidnapper/etc want? In conclusion: I think the Magic Mirror may know a lot about Faith (more than a simple gaze through the mirror, what happened to her, where she is if she is alive, and he is in it voluntarily and provided info to the actual murderer (I use italics with 'murderer', because there is no solid evidence that they are really dead, or even murdered at all).
Of course, like so many other things, this is a mere theory.
