Watch how the team pulled this off

When Oprah sees Jackie, the 13-year-old inside of her is unleashed. "When Jackie Jackson walked through that door, I don't think I've ever seen Oprah scream that loud," Leslie says. "I haven't seen that look on her face in a long time, so that was really, really fun."

Oprah is flustered. "Suddenly, your brain is going like this," she says. "So I had a deeper love than I knew when he showed up."
