Root arrives as one of the show's most chilling villains, a contract killer and hacker who treats human beings as bad code to be deleted. Coldly brilliant and utterly without conscience, she becomes obsessed with the Machine, which she reveres as a perfect god trapped by its small-minded human keepers. Her early goal is simple and terrifying: free the Machine from Finch's leash.
What makes Root extraordinary is her transformation. Once the Machine begins speaking to her, choosing her as its analog interface, she finds the connection and purpose she never had among people. The fanatic becomes a true believer with a heart, a faithful and increasingly tender soldier whose devotion to the Machine and to Finch reshapes everything she does.
Her romance with the lethal Sameen Shaw gives her a humanity that her early carnage never hinted at, and her loyalty to the team becomes total. Root's story ends in heartbreak, but her voice does not, and her sacrifice echoes straight through return 0 and beyond. Few characters travel further from monster to beloved than she does.
