Some more minor details have been revealed in "A Crooked Mile", so I'd like to take a look at some of the questions they raise.
Mainly, in the "Official Compenduim of Authorized Articles" that you find in Crane's desk, there are two items besides the Ring of Dispel that are of great interest to me: The Witching Cloak and a Sword.
Two very important things stand out. First, the cloak is in the care of Boy Blue, and is capable of both "transmogrification" and "teleportation" with a picture of the wearer turning into a bird, as can barely be made out in the discription. This is very bad news. Second, the Sword has a nice picture of someone being decapitated and has the words "anything with a single cut" in its description; also very bad news. But worse, it's in the care of Snow White.
In episode one, after she finds Faith's head and is discussing it with Bigby, she asks, "What could do something like that?" This is most unusual. So not only are all these items under one roof (The Woodlands Luxury Apartments), but combined they could make for a virtually unstoppable killer. Thoughts?
