You have couple shows left.

Everyone who knows you from the show loves you.

I got to, um... [ Cheers and applause ]

Yeah. -Thanks.

-But another guy that we really loved

was Luke Perry.

-Mm. [ Cheers and applause ]

-We were all -- I was --

[ Cheers and applause continue ]

I kind of grew up on Luke Perry,

and I was just kinda shocked

by the news that he's not with us anymore.

-Yeah. -It was...

I just couldn't really kind of wrap my head around it.

I can't even imagine how you feel.

-It was, uh... Yeah, it was --

[ Sighs deeply ] Everyone was pretty shocked,

and I think, um...

It's not every day you come across a guy like Luke.

Like, Luke is the kind of person

who did everything you can to make whoever you are,

no matter how big or small you are,

feel comfortable and feel welcome.

And I...

I think -- Yeah, there's not really --

It's hard to kind of put into words

how that makes me feel but [Inhales deeply] yeah.

-I mean, he was your -- He was your dad on the show.

-Yeah, we had a really close relationship.

He would call my parents every week

and, like, keep them updated how I'm doing.

Like, if I had a cold or something,

he'd be like, "I took some Gatorade

to his apartment the other day."

-Is that right? -Yeah, him and my dad

were always texting each other and stuff,

and he made an effort --

He made such a huge effort from the very beginning.

And to me, I was like -- I don't know --

like, "I wish I could be like that," you know?

-Well, you can. You can be like that.

-I can. -You are like that.

[ Cheers and applause ]

You haven't really talked about it,

except on Instagram.

I follow you.

-You follow me on Instagram? -Yeah.

I have to. Come on, man.

We're boys.

-We are, yeah.

I got to take care of you.

I don't know if I'll bring Gatorade to your apartment

but, I mean... -[ Laughs ]

-But you put a picture of Luke,

and you put, "Rest in love, bro."

[ Audience "awws," cheers ]

-My favorite photo of Luke.

-It's a great photo.

Why did you choose that photo of Luke?

-I just think he's in complete

and utter peace in that photo, you know what I mean?

Like, look at him.

-He's just living his life. -Yeah, living the dream.

-Living the dream, yeah.

It was very beautiful that you did that, buddy.

Well, we have a couple episodes left of "Riverdale."

-Yep. -Can we set anything up --

What's gonna -- No spoilers,

but what are we gearing up towards.

-Oh, we're gearing up to some pretty intense stuff,

actually, the last couple episodes.

-Oh, really. -Real exciting stuff.

[ Laughter ] -Are you gonna get --

-There's one last fight of the season,

'cause Archie's, like, fighting now and stuff.

-Yeah.

-It's between me and Mark Consuelos.

-What?!

-And Mark got so ripped.

-Oh, he's jacked. In general, he's jacked.

-He was, like, dehydrating himself.

I was like, "This old man has,

like, put me to shame."

[ Laughter ] It was crazy, bro.

-Oh, my gosh, dude.

People are going to go nuts

to see two good-looking dudes fight each other.

Okay, here we go. [ Laughter, crowd cheers ]

I do want to show a clip

Here's KJ Apa in "Riverdale."

Take a look at this.

-Are you sure about this?

I love seeing you back in the ring,

but if the tournament's too soon,

we can send Mad Dog.

You can keep training and go next year.

-No, I'm ready. It's just, um...

I was just wondering...

what are you doing for prom.

-Prom? -Yeah, I thought,

maybe, we could go together.

As friends. -[ Chuckles ]

-I would honestly love that.

-Yeah, great.

[ Cheers and applause ]

-Hey, we love you, buddy. Thank you so much.

Come back whenever. KJ Apa, everybody!
