Reasons for Bloody Mary being dead: (add other reasons for her being dead, can't come up with anything else as I'm a "Alive" supporter. Will add it to this list!)
 * Bloody Mary revealed herself when the clones died and jumped up to the pipe where she grabs a glass piece and prepares to make her final stand against the wolf, but unfortantly dies when he kill her.

Reasons for Bloody Mary being alive:
 * Her status (and infobox for that matter) mysteriously doesn't appear in the end list of the characters who are alive and deceased which is shown when the episode "Cry Wolf" is completed.
 * The supposed Bloody Mary who used a glass dagger to kill Bigby could've been just another clone of hers, as their was many  of them at the time.
 * When a clone died, glass was shattered from its body. The same thing happen to the supposed Bloody Mary, so this further supports that she could very well be another clone.

Even though we don't have a full list of facts on both sides, it is obvious her current status should be changed to "Unknown"!
