Its a lot of fun.

Its just been really nice to get back out there and shield it up.

James is going to be faced with the possibility of his identity being revealed.

How will he handle that?Thats a great episode.

I was able to tell my first experience with racism, when I was 7 years old.

Allowing an actor to infiltrate the character in that way.

I honestly have never experienced a television show, or a film, that spoke about race so eloquently.

We dont frame the debate this way, but we should.

Racism, just like sexism, is one of the earliest forms of bullying, right?

Its just becoming acceptable because its ingrained in our culture.

It was one of the highlights of my career.

I didnt even realize.

I didnt realize how much confusion I had.

Honestly, in some ways I felt sorry for the adults that were doing it to me.

Theres a pathway for healing with this.

I dont have another word for it, really.

I think we have to top what we did last year.

We have to, its a cliche, but save the world again.

I think this whole season has been a lot more grounded, you know?

I think thats really cool, because it almost makes the end of the world believable, right?

No, because of these guys.
