Rachel fears for her life due to a conspiracy involving the deaths of her colleagues, whom she believes were killed for knowing sensitive information.

Charlie is startled and surprised by Rachel's sudden appearance and her conspiracy theory.

Rachel is a statistician specializing in demography.

Rachel's death was initially ruled as a non-accidental overdose of prescription medication.

A second autopsy reveals that Rachel died of asphyxiation, suggesting murder rather than suicide.

J. Everett Tuttle is a billionaire with connections to the deceased individuals, suspected of being involved in a conspiracy.

The conspiracy involves electoral fraud, with statistical anomalies suggesting rigged voting machines in the Brasher election.

The FBI gets involved after Charlie agrees to help Rachel and her connection to the conspiracy becomes evident.

Jane Aliano is a key witness who was involved in designing software that could alter voting machine results. She agrees to testify against Tuttle.

Oswald helps Charlie with statistical analysis and realizes the significance of their work in exposing the conspiracy.

Charlie publishes an academic article detailing the conspiracy, which gets leaked to the media, leading to widespread public awareness.

Despite the exposure of the conspiracy, Tuttle remains untouchable due to a lack of direct evidence linking him to the crimes.

The episode suggests that some conspiracies can be real and involve high-level manipulation, but proving them can be challenging.

The episode ends with Oswald realizing the impact of their work and feeling a sense of pride and purpose.
