Greenstreet takes up a self imposed challenge of camping overnight - alone - adjacent to the claimed haunted hot spot - an old homestead.
Most of the episode is actually taken up with detailing various inconsistencies involving the key players.
Meanwhile, 'back at the ranch' he did experience a couple of overnight stay incidents that his rationalizing as mundane, looks rather thin:
1: Walk through the ruined homestead at night: 19:15 to 20:30
Thumps/knocks. He put it down to either shifting timber from walking around, or a scampering animal.
But one would expect creaking sounds synchronized to walking steps on the former scenario.
Or characteristically scurrying animal motion sounds not just a series of isolated knocks in the latter one.
2: Walk along dirt trail to the property west gate bordering native reserve land, and wait for strange sensations/happenings: 29:14 to 31:17
First a distinct uneasy feeling comes over him (just as others had reported).
Followed by an inexplicable triggering of portable lightning detector.
And to round things off, a sudden burning feeling in eyes and face, quickly becoming inflamed and swollen eyes.
He makes no effort to explain the first two, but subsequently claims the burning & inflammation was likely a natural allergic reaction to being in the region not just Ranch.
Which ignores the sudden onset just at the time of west gate visit. Coincidence seems very unlikely.
For sure though he has exposed the dubious nature of what Skinwalker Ranch is really all about as a business venture of sorts, far more than a bona fide 'long-term scientific study of the paranormal'.
