There's been quite a bit of speculation already over whether or not Bigby killed the actual Bloody Mary, or if it was just another one of her clones. Many people on various sites have stated that she likely wasn't killed by Bigby, some even saying that she glamoured herself as Nerissa and betrayed the Crooked Man, explaining how Nerissa, who was supposedly trapped, managed to get free. Some have claimed the glass face that's zoomed in on as Bigby walks away shows an obvious grin, as if Telltale is trying to say she's still alive. Some say she'll be in Season 2, if there is a Season 2. Some say that her death was too obvious to have been faked, and that she's definitively dead. However, when it comes down to it, no solid evidence exists on whether or not the final Bloody Mary was killed. A variety of theories have been made, and several users, myself included, have had conflicting opinions on her status when it comes to editing her article.
So then, what do you think happened to Bloody Mary? You can give a reason to your vote or not, but it'd help to gauge the mixed opinions on her fate.
Myself, I think she's Unknown. I think all of the buildup to her couldn't end in just one scene, and various hints throughout the game make me think she isn't quite dead yet. Look at Kenny from The Walking Dead, Telltale's other famous game. After Episode 5, many people considered him dead. There was legitimate evidence to support it. But his death wasn't made explicit, and he came back later. Had Bigby killed Mary in her human form, not just shattered her like he did the other clones, I would definitely say she's dead. But as it stands, I think that not enough evidence exists on either side to 100% confirm she's dead, or alive. I think that it's best to say she's Unknown, or at least Presumed Dead. If Season 2 rolls around and it's stated she got killed off or is still alive, fine, but until then, I don't think either answer's correct.
