Sheldon: Paige?
Paige: Sheldon?
Bobby: You know him?
Paige: Yeah, no, we go way back.
Sheldon: What are you doing here?
Paige: Would you believe me if I told you I was working on a femtosecond laser in the engineering department?
Sheldon: Yes.
Paige: Then that.

Paige: Sheldon?
Sheldon: Paige?
Paige: I'm so happy to see you. Are you happy to see me?
Sheldon: Not immediately.
Paige: That's okay. I'm happy enough for both of us.

Paige: You're being weird, and not in the usual way. Guess that's my life now.
Sheldon: What do you mean?
Paige: Everyone is acting weird. My mom is going on dates and my dad is acting like a child. My sister's crying all the time. I just wish that everything could go back to the way it was. I don't think it will.
Adult Sheldon: It turned out I was really good at listening. The trick is to sit there, and when you want to leave, don't.
Paige: I have to live in two separate houses. And my grandma says the meanest things about my dad. I know that everyone is upset that I'm not doing well in school. It's just hard to care. Everything that used to seem important to me just doesn't anymore. So I guess, really, I just feel alone.
Sheldon: That sounds hard.
Paige: Yeah, it is.

Sheldon: Paige? Why are you here?
Paige: The lecture.
Sheldon: Well, if you're looking to jump the line, I don't do cutsies.
Paige: No, I'm actually part of the lecture. Professor Patterson is my mentor at U.T.
Sheldon: Really? You're part of the quantum gravity team?
Paige: Yeah, it's actually really interesting. We've been examining all...
Sheldon: I know what it's about. It's why I've been waiting in line for three hours.
Paige: Wow, three hours to see me speak? I didn't know you were such a fan.

Adult Sheldon: Many cultures throughout the world relied on percussion to send messages across long distances. For example, the West African dundun was used to imitate human speech... [loud music playing] ...while I used my fist, the wall of my dorm, and Morse code to send a message.

Bobby: [opens door] Yeah?
Sheldon: I'm here to talk to you about your music and your abysmal Morse code skills.
Bobby: What?
Sheldon: Four dots is just the letter "H." Was your message "Huh"?
Bobby: What?

Sheldon: You know she's not old enough to drink beer.
Bobby: I'm not old enough to drink beer. [chuckles]
Paige: Yeah, one second. [closes door] Come here.
Sheldon: Did I convince you that drinking is wrong? Good for me.
