EP Jonah Nolan gave these ominous spoilers to TV Line: "As taxing, difficult and ultimately lethal as the battle [with HR] was, that was just the beginning of the challenges put in front of our heroes." Added EP Greg Plageman: "We're going to see these various entities jockey for control of The Machine or at least something commensurate with it."
And that's where Root comes in. When asked by the website about Root's insistence that "something big is coming," Michael Emerson claimed to be unsure of Root’s meaning,
“but that line from her made my hair stand on end, because she clearly knows things that we don’t know...She’s a confidante in the Machine in a way that no one else is, so I’m sure Mr Finch lays awake at night wondering what the heck she meant.”
Is Root on her way to being seen as an ally to Team Machine? Slowly, and not at all surely, said Emerson: “Mr. Finch is warming to her, a bit. She’s proven certain things, and it’s not all bad. But it’s all crazy."
Do you think Root can be trusted?
