Why Does Aggie Choose to Write Nile Jarvis’ Biography?

Writing Nile’s biography gives Aggie three things:
-
A renewed sense of purpose
-
A way to investigate Teddy’s sudden disappearance
-
An excuse to explore the unspoken tension between her and Nile

It’s through this collaboration that Aggie gets her first look at the truth behind Nile’s carefully maintained façade.

Is Nile Jarvis a Murderer in The Beast in Me?
The short answer: yes, but the series takes its time revealing how deep Nile’s violence runs.
Abbott’s secret hack into Nile’s computer uncovers a live video stream of Teddy being held captive. Nile abducted Teddy as a twisted act of affection toward Aggie a gesture he believed would satisfy her desire for revenge.
This discovery unravels Nile’s world. As soon as Abbott confronts him, Nile kills him, then heads straight for Aggie. From this point on, Nile’s predatory instincts fully surface.
But the pressing question remains: did Nile also murder Madison, his missing wife?
The revelation comes later, through a flashback episode. Madison did not die by suicide as initially suggested. Instead, she was the FBI’s mole inside Jarvis Yards, leaking information about the family’s use of cartel funds. When Nile discovered her betrayal tipped off by Nina his violent response ended Madison’s life. His father and uncle buried Madison’s body in the concrete foundations of Jarvis Yards.
By the time Aggie uncovers all of this, it’s almost too late. Nile already knows she’s been digging.
