Herman agrees: “I’m very grateful for that.”

I remember me, my sister.

and my mom were at a Halloween store in San Diego.

“Yeah, I am.”

[Laughs] I’ve had some really nice notices, even at the mall.

I feel like I’m much more comfortable now.

ERIS BAKER:I don’t think I fully understood that I was on an NBC show.

I didn’t understand how big that was.

I was just happy that I finally got a part.

I’m this kid that’s basically growing up on a No.

It was like, “Oh my God!

Throughout all of the recognition and the fame that has surrounded the show, they haven’t changed.

And our car scenes and family gatherings…. Those are always really fun.

BAKER:Of course, Faithe would say that.

I love our breakfast scenes.

[But] the moment I will definitely take with me is when Tess came out.

Speaking for myself, I was very terrified.

I had never cried or been vulnerable on camera before.

I’m going to remember that scene forever.

ROSS:The scene where Deja tells Randall that he’s her day 1.

I remember that setup and just the atmosphere being so pure and genuine.

It was just raw… it was real and honest.

I’m definitely the one who loves to joke around.

BAKER:I think Tess is very comfortable with being open and being vulnerable.

She’s a great communicator.

I’m not that comfortable with being that vulnerable.

In so many ways Tess has taught me about communication.

ROSS:I take a stab at listen more than Deja.

[Laughs] Especially when it comes to people who are truly wise.

I was always super nervous, so it’s always a learning process when I’m on set.

I felt like I’ve learned my craft from being around all the adults.

BAKER:Just being around Susan and Sterling I’ve learned that acting is a lot like tennis.

You hit the ball back and forth.

ROSS:“Just go for it… just do it.”

Sterling gave me that advice.

I mean, Sterling… he’s all the way up here.

[Laughs] He’s huge!

But his personality he’s so true to his weirdness.

And there’s so much freedom to that.

Life after This Is Us

HERMAN:I’m definitely finishing up school.

That’s going to be pretty exciting.

I want to go behind the camera 100 percent.

I want to break out to film.

As an actor, I have so much to learn.

I’m only 16.

I’m still finishing up high school.

ROSS:Eventually I will be going to college.

I do have some projects that I will be working on that I cannot say what they are.

But yes, you will be seeing more of me.
