Theory about the foot (spoilers)
So, at this point I'm sure we all know the general Blair Witch franchise theory about how the witch has the ability to manipulate time. Okay, here's my theory concerning the foot. Not precisely why she got so infected and *beep* up and why it was like…moving, but.
Anyway, at a certain point in the movie where Ashley wakes up and goes and talk to Lisa, starting her, we see Ashley walking back to the tent. Then Lisa looks down at her foot and it SEEMS that Ashley's walking just fine. Like as if her foot miraculously healed. Idk if you all caught that. The film INTENTIONALLY showed that though. My theory is that the reason why her foot healed and why Ash was able to run and climb trees like a monkey is due to the fact that the witch manipulated time many times throughout the film and in those moments where Ashley was walking back to her tent and when she was climbing the tree, we were at a point in time where Ashley's foot had not been injured yet.
Thoughts?
