Sterling K. Brown Says He Knows How 'This Is Us' Ends For Randall (Exclusive)

The star coyly addressed one particularly cryptic scene from the season 2 finale that has fans speculating like crazy.

Sterling K. Brown is playing things very cautiously when it comes to accidentally revealing any This Is Us spoilers.

While Brown admits that he has a "preliminary" idea for what is going to go down in season three, the star tells ET that he's still got a few weeks to go before sitting down with creator Dan Fogelman for a full outline for his character, Randall Pearson.

"I have heard an outline for [my character]," Brown told ET's Leanne Aguilera at NBCUniversal's upfront presentation in New York City on Monday. "I like it. I'm pleased. [But] I'm always pleased, so nothing is new."

While Brown seemed excited to talk about the upcoming season, he found himself having to be super cautious, especially when asked about one particularly mysterious scene in the dramatic season two finale that has had fans freaking out since it aired in March.

The dramatic finale features a flash forward into the future and shows an older Randall talking to his adult daughter Tess in which the pair share a very cryptic exchange.

"It's time to go see her, Tess," Randall says. 

"I'm not ready," Tess replies, shaking her head.

"Me neither," Randall concedes. Clearly, the father-daughter duo are not looking forward to visiting this mysterious "her," whose identity has been fueling fan theories for weeks.

However, when asked about the rampant speculation that the "her" they're talking about is actually Randall's wife, Beth -- who has either died, has a terminal illness or had a falling out with the family, depending on which wild and totally baseless fan theory you read -- Brown did everything in his power to carefully navigate the treacherous terrain of a response.

"I know who I'm talking about [in that scene]," admitted Brown. At first, this seems obvious; however, not every actor on This Is Us is always privy to the twists and turns the show throws at them and their characters.

For example, Susan Kelechi Watson -- who plays Beth -- doesn't know who the "her" refers to, but told ET that she thinks they are, in fact, talking about her character.

"Yes, that is what Susan thought," Brown said when presented with his co-star's comment, pointedly not confirming or denying the possibility.

While he wasn't able to give any specific details, he admitted that it "will be a while" before fans get the answers they are looking for.

"This is what I can tell you: The show kind of knows where it ends, and future Randall [in the scene in question] is sort of in a place [that occurs] towards the end of the show."

"I can't say any more than that," he added, smiling.

This Is Us season three premieres this fall on NBC.
