Susan Kelechi Watson Says This Actor Was the Biggest Pot-Stirrer on This Is Us

Susan Kelechi Watson appeared on Watch What Happens Live on Thursday, June 16, and spilled some fun tea about her This Is Us co-stars. In a rapid-fire game with Host Andy Cohen, Watson gave superlatives out to Mandy Moore, Sterling K. Brown, Milo Ventimiglia, Justin Hartley, and Chrissy Metz⁠—and they were too good. 

See a recap of everything Watson said, below: 

Her bestie of the group: Sterling K. Brown. 

Who forgot their lines the most on set: "People were pretty good about lines, I 'gotta be honest." 

Who Watson texted the most when the cast was on hiatus: Chrissy Metz, Mandy Moore, and Sterling K. Brown. 

Who the most long-winded is of this group: "Justin tells a good story. I wouldn't call it long-winded, but he tells a good story." 

Who the biggest pot-stirrer is of the group: Sterling K. Brown. 

The person in this group most likely to pick up the bill at dinner: Mandy Moore and Justin Hartley. 

Who the first person would be to sign up for a This Is Us reboot: Justin Hartley, Mandy Moore, and Chrissy Metz. 

It remains unclear what "pot-stirrer" means, but our guess is that Brown was the biggest on-set prankster who liked to have a good time. And of course, we know that he and Watson had an ironclad bond while working together. "So much of what I do is with Sterling," Watson said in an NBC video. "A loving couple who's been together for a long time and also that is willing to do life at its deepest levels with one another. They're willing to do that together." 

And Brown added, “[Our working relationship is] special, and it has this really delicate balance to it. It’s always felt easy."
