Pushing further into the dense woods than anyone has ever dared, Boyd and Sara find a tree adorned with clinking glass bottles. Inside one, they find a slip of paper dated "1865".

This episode perfectly sets up a three-pronged cliffhanger heading into the Season 1 finale: the completion of the antenna, the bottom of the basement hole, and Boyd's survival in the deep forest.

This heavy, atmospheric episode masterfully balances the desperate hope of building a way out with the overwhelming, claustrophobic dread of the surrounding wilderness. 🛑 What Went Down

Fans are heavily speculating that the sudden blaring sound and illumination are coming from a lighthouse hidden deep within the forest.
