Last we saw Root on Person of Interest, she was taunting Reese that her pursuit of The Machine is not over. And as Amy Acker spoiled to TVLine, her worst is yet to come:
“I make it back eventually, later in the season. And when I do, it’s a roller coaster of lots of trouble….A lot of stuff escalates.”
Person of Interest takes this week off for Thanksgiving (there's a repeat), but will return with a new episode on November 29.
