Early-nineties CGI alert! It's Perpetual Night in Owl Cave, and Cooper, Truman, Andy, and Hawk approach the triangular symbol with much awe. Cooper posits, "Two symbols combined into a larger whole…but for what purpose? The tattoos are the question. This must be the answer." An owl watches Cooper approach the cave wall, then flies wildly around them. Discouraging PETA enthusiasts everywhere, the normally docile Andy goes for the owl with his pickaxe, which gets caught in the cave wall. The four then watch in shock as a Styrofoam panel slides out of the wall, and another symbol, kind of a triangle with two arms, comes sliding out of the wall toward them. Cooper approaches and describes it as a "petroglyph." And not a triangle spider, as I thought would be most descriptive. Cooper sets up the show's remaining dramatic action in alerting them, "I have no idea where this will lead us, but I have a feeling it will be a place both wonderful and strange."
