I don't know about you, but I don't think I'm ready for this! Tonight is the second to last episode of This is Us. And more importantly, it's the one where Rebecca passes away. Mandy Moore said it's overwhelming, and Sterling K. Brown (Randall) said we all better have a full box of tissue ready. He also said it's going to "wreck us" I'll be staying up late to watch tonight. What about you? Will you be watching. Check out a sneak peek below, and an interview with two of the stars talking about the impending end.
