Things take an even darker turn after Danvers and Navarro discover the final video Annie K. shot moments before her death, and some digging reveals that she was in an underground ice cave somewhere in Ennis. Danvers corners Otis Heiss (Klaus Tange), the mapper of the ice cave system, who has a history of disorderly conduct and substance abuse. He reveals that Raymond Clark (the only Tsalal Arctic Research Station scientist unaccounted for, who was in a relationship with Annie K.) is hiding in the Night Country. This deliberate phrasing indicates that “Night Country” doesn’t refer to Ennis as a whole, but to a specific place that is hidden for a reason — perhaps some sort of liminal space. Yet Heiss also says that they are all in the Night Country now, which feels like a warning and the prelude to something terrible.
A lot is going on adjacent to the investigation. Navarro is seen to experience more intense visions after the death of her sister, Julia, and the clues connected to the case point to the spiral time and again. It is still unclear what any of these things mean, but the Night Country probably harbors dark secrets that might be the key to solving both the Tsalal incident and the Annie K. murder case. It is impossible to ignore the implication that Night Country might have connections with something hidden in the ice — a theory that is supported by the Annie K. video evidence and the fact that researchers were sequencing an extinct species buried deep inside the ice before their demise.
The fact that Tsalal is funded by a conglomerate named Tuttle United certainly does not help matters, creating direct threads to season 1’s central antagonists.
