[Sivana looks at Shazam's costume]
Dr. Thaddeus Sivana: What made you so worthy?

Dr. Thaddeus Sivana: Give me your power.
[Sivana removes his sunglasses, revealing the Eye of Sin as his right eye]

Shazam: That's because I am one. I-I'm a kid! You don't wanna hurt a kid, do you?
[Sivana punches Shazam down back to the city]

[Billy arrives at his mother's apartment and knocks on the door]
Billy's Mom: Just a second.
[she opens the door]

Billy Batson: Oh, I'm not. You probably don't recognize me, but...
[Billy shows her his compass keychain]
Billy Batson: I found my way home. Mom. It's me.
Billy's Mom: Oh, God. Is it?
[Billy nods, then approaches to hug her, but she stops him]
Billy's Mom: Um... hang on.
[she closes the door]
Billy Batson: That wasn't Dad, was it?
Billy's Mom: No. Listen, son... It's really you, huh?
Billy Batson: I didn't mean to run away. You know that, right? I let go, but it was by accident.
Billy's Mom: Yeah, no. I know, yeah. I saw you.
Billy Batson: What?
Billy's Mom: I saw you after. So, it was never your fault. Look, I was 17, okay? And my daddy kicked me out. And your dad just decided not to be a part of anything. And I was hurting, and I was screwed up.
[pause]
Billy's Mom: Look, it's just once I saw you with the police, I realized they could do a better job taking care of you than I ever will. But you're good, right? I mean, you landed on your feet. Because, I mean, you look real good. It's just... now is not a really good time for me, Bill.
Billy Batson: All I wanted to do is... let you know I'm doing good, but I have to get back to my real family. Here.
[Billy gives her his keychain]
Billy's Mom: What's this?
Billy Batson: You might need it more than me.
