FOLLOWER SUBMISSION THEORY
Here me out. I know it’s far fetched but what if Maya’s the one with the twin? Because the moment that I found out that she ‘died’ so suddenly without us seeing her body just like Ali’s and when their body was found ‘dead’ the same background music played. So I became really suspicious ever since. Plus with this post by alisondilaurentis1 (picture above credits given) looks like Maya to me.
I was also thinking why she’d be helping Jenna and hits Toby on head at the night of the lodge. Maybe he has something to do with Maya’s/twin’s death or something else we don’t know yet that’s why she did it and A also targeted Toby’s house. (I might just be over thinking this part though)
Moving on.. Either Maya was really dead or her twin was the one that died now Maya or the twin’s taking revenge somehow or is helping A. Otherwise, how could the coroner make a huge mistake unless the face was deformed or burnt (and uses the Emily mask?!) somehow that you wouldn’t recognize it easily. Because unlike Ali’s body, hers were found instantly not for 2 years or so.
I’ve always thought this to be Jenna, no offense to your theory, but Jenna’s hair was very similar to this style. Also, it was confirmed in an episode that Jenna and Shana were in the woods that night :)
