On Monday's episode of NBC's freshman psychological thriller, The Enemy Within, Carpenter's Erica Shepherd, a CIA agent convicted of treason against the United States after she gives up four names of the agents working against terrorist Mikhail Vassily Tal, has an emotional reunion with her teenage daughter, whom she hasn't seen in years. For the past three years, Erica has been jailed in a supermax prison and labeled a traitor.
"I can't believe I have a sophomore," an awestruck Erica says to her 15-year-old daughter, Hannah (Sophia Gennusa), in ET's exclusive clip.
"It's okay. It's better than being a freshman. And, I get my license soon," Hannah says proudly.
"Your driver's license? Hannah, I don't know how I feel about that," Erica replies, putting on her mom hat. When Hannah tells her it's not a big deal that she's already driving, the years Erica has lost with her daughter becomes too much for her to bear.
When Hannah asks her mom whether she's cooperating with the FBI in her assistance of tracking Tal down and bringing him to justice once and for all, Erica isn't interested in talking about that at all.
"I don't want to talk about that. I want to listen to you. I want to hear everything about you," Erica says, before asking about their new home in an effort to make their brief time together count. "Hannah, please talk to me. I don't have a lot of time..."
Hannah takes a beat before tearfully addressing the elephant in the room: "Why did you do it? I need to know mom! Tell me." Erica declines. "We didn't want to move. We had to."
Erica tries to keep the conversation pleasant, but the more she punts the question, the more frustrated and emotional her daughter gets. "But you won't tell me why." Somehow, Erica maintains a stoic face, which prompts Hannah to make a brash decision. Watch ET's exclusive clip to see what happens next.
