Kate McKittrick (Dervla Kirwan) has been a rather shadowy figure in Ennis so far, only glimpsed during her tense conversations with Danvers, whom she appears to despise because the detective had an affair with her husband at some point. As an executive at the Silver Sky mining company, Kate’s presence has always been subtly suspicious, as it is clear that she is indirectly responsible for the pollution in the town’s water supply that has been claiming the lives of the local populace. Apart from this, she seems to have a close relationship with Hank Prior (John Hawkes), who was revealed to have hidden crucial evidence from the Annie K. case, which also casts doubts on her potential involvement (more on this later).
After Kate and Ted call Danvers for the meeting, they reveal that the official report for the case behind the frozen researchers’ deaths has been chalked up to an avalanche. When Danvers counters that this explanation is not plausible, Ted doubles down by claiming that the report supports the nature of the injuries on the bodies, but completely disregards the grander context of the crime scene. Kate interjects by smugly stating that it is a relief that no murderers are roaming around in Ennis — a curious statement, as this meeting is called right after Danvers and Navarro locate an ice cave owned by Silver Sky.
A furious Danvers rightfully accuses Silver Sky of wrongdoing: after all, Tsalal’s research is backed by them, and their pollution numbers directly contribute to stillbirths and deaths, presenting a conflict of interest. While Kate feigns innocence, it is clear that Silver Sky is responsible for everything going down in Ennis.
