I believe we're all farmiliar with the outcome of this temple run. In case you're not: Red Jaguars, artifact in Lightning Ball Room, Ben goes in first, temple gaurd in Laser Light Room, Removed in the Swamp, Renee goes in next, passes half pendant in Swamp, hesitates between Dark Forest and Swamp thinking if she should go back for it or not, but she doesn't, reaches hand into tree, temple spirit in tree ends run.

So that's that, right? Maybe not!

However, there's also a chance that Medusa's Lair could've just been a dead end. I'm not sure.
This run was very peculiar to me. I have a theory that even if Renee tried to bust through the rock wall, it wouldn't have broken down... Cuz that would've been too easy, right? And the temple spirit was in the tree farthest away from the breakable wall. However, we'll never know... and we'll also never know if they could've gone upto Medusa's Lair.
So, someone else watch this temple run and tell me if i'm crazy or not cuz it really looks like the door to Medusa's Lair opened to me.
