Timeless is traveling back to 1865, where the team’s next mission is saving President Abraham Lincoln from getting assassinated!

ET debuts an exclusive sneak peek from Monday’s episode of NBC’s freshman time-travel drama, in which Lucy (Abigail Spencer) meets Abe’s eldest son, Robert Todd Lincoln (Neal Bledsoe), at the famous Ford’s Theatre where his father was killed more than a century ago.

“You know, my father’s coming to the play tonight. Will you see him?” Robert asks Lucy, who fibs and says she’s an actress named Juliet Shakesman.

“It’s … not very good,” Lucy answers, trying to hint that the play might not be the best thing for his father to do that evening. “Should I tell him not to come?” Robert charmingly responds.

Lucy attempts to change the topic, asking him how it feels to have the president for a father. “What’s that like for you?” she asks.

“He casts a long shadow. It’s not one I mind living in,” Robert admits. “I’m proud of him. He’s done some great things, and he’s just getting started.”
