While Randall (Sterling K. Brown) and Beth (Susan Kelechi Watson) remain one of TV's current favorite couples, the two have had their issues on This Is Us Season 2.

Not only has Randall been annoying Beth with his lack of career direction, he's also pushed her into purchasing a dilapidated building with him to help feel closer to his recently-deceased biological father, William (Ron Cephas Jones).

In the penultimate episode of Season 2, we'll learn more about Randall and Beth's former foster daughter.

We're not blaming Beth for her frustrations—her hubby has been a little off the rails and scattered in his tasks. And when things got rough between the pair in Vegas in the February 27 episode, we saw that tension finally bubble to the surface. By the end of the ep, they seemed to settle those issues, with Randall apologizing for calling his wife "heartless." But something tells us it's not over yet.

Ahead of his upcoming hosting gig on Saturday Night LiveSterling K. Brown teased some scoop on the third season of This Is Us, now that we're just over a week away from the March 13 Season 2 finale. In that episode, fans will watch Kate (Chrissy Metz) and Toby's (Chris Sullivan) wedding, and Brown hints that a number of other cliffhangers will be set up for next fall.

A new theory has 'This Is Us' fans preparing for the worst.

The actor said to People  of wrapping Season 2, "It was bittersweet. We love each other and we have a wonderful time working with each other, but we’re also excited because we know how the season ends and it ends very strongly and also opens up very interesting storylines moving forward into Season 3.”

The promise of a strong ending makes us hopeful that we'll end on a happier note. Of course, as viewers of This Is Us know, no one is ever fully content on this show, so the idea that Randall and Beth will struggle in their relationship isn't out of the realm of possibility.

The showrunner previews a lighter end of the season.

"There will be a bit of an exploration of marriage with regards to Randall and Beth going through times that aren’t all sunshine and rainbows,” continued Brown. “And that’s not to say that they are in danger of parting ways, but marriage is real and takes work.”

Even as the actor confirms some fears fans have had about this power couple, it at least sounds like it won't be irreparable damage. At least, let's keep our fingers crossed!
