I can't help having a car-crash curiosity about what Scorpion will report.
Scorpion is uncertain that he really has a third eye, uncertain whether he can open it, uncertain that there is a spirit world, uncertain that his uncertain third eye can actually see the uncertain spirit world, and uncertain of how he could tell if he is seeing the spirit world he's uncertain of with the third eye he's uncertain of...
On the other hand, we know people regularly misinterpret what they see, or see things that aren't there. We know that sensory deprivation, e.g. shutting your eyes, will cause false perceptions due to noise in the system, and may eventually produce hallucinations. So sitting with eyes shut concentrating on vision for lengthy periods is very likely to result in seeing things (a really fun example is the
Strange Face in the Mirror illusion, sometimes called the Bloody Mary illusion, or the Monster in the Mirror illusion, which involves staring at oneself in a mirror in a room so dark you can barely make out your face).
I'm curious to see how Scorpion, if, as is quite possible, he sees something, will reject the most probable explanation, that is based on well verified experiment, in favour of a fiction, the principles of which he admits to being uncertain of in every respect...
ETA - apologies for the convolution of that last sentence, I wasn't thinking clearly.
