I Am Starting To Think That The Girl Hiker Will Be Pit Girl For A Couple Of Reasons:

I am starting to think that the girl hiker will be pit girl for a couple of reasons:

First of all the hunt of pit girl and her butchering feel so emotionless, like even with ben there was some sort of emotion (specifically seen with Nat and Misty) and even if these girls going kookoo I can't see the more sensitive memebers having no reaction (at least not from where we're at now) to pit girl at all, at least not if she's one of their own

Second of all the hikers that found them are specifically bird watchers and if you go back to the pit girl scene in episode one you here the girls making a bunch of u guessed it, bird noises. These sounds also mean the girls are playing with their victim, and if it was the hiker girl taunting her with bird noises seems accurate.

As well I think the pit girl scene is coming sooner then we thought considering Tai and Van talking about how winter is coming soon and how back in season 1 it literally came overnight. Not only that but given it seems they're debating waht to do with the hikers it's possible they settled on letting one go back to get them help while they keep the other hostage to keep them silent on what they walked in on. We also know the girls are capable of holding someone prisoner for a while as seen with ben which once again renforces the hostage thing.

Finally we have the fact that pit girl, as her name indicates, fell into the pit. Now we know Mari one of the two viable candidates for the pit girl allegations obviously knows where it is and though we have never seen gen see it on screen I doubt they never end up revisting the hole later. But you know who wouldn't even know the existence of this pit, a hiker.

obviously I could be super far off but like might as well through my theory into the ring lol
