Quote from the episode Carbon Dating and a Stuffed Raccoon
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.
Quote from the episode A Rival Prodigy and Sir Isaac Neutron
Paige: You actually believe in the multiverse theory?
Sheldon: Very much so. It's the most elegant interpretation of quantum mechanics.
Paige: So you really think there are an infinite number of universes?
Sheldon: Stephen Hawking believes it, so, yes, I do.
Paige: Well, if there are an infinite number of universes, I think that theory's dumb in all of them. [CHUCKLES] This is fun.
Quote from the episode A Stunted Childhood and a Can of Fancy Mixed Nuts
Paige: Hi, Sheldon.
Paige: What are you doing?
Sheldon: Chemistry homework for extra credit.
Paige: Cute, I did that last year.
Quote from the episode Body Glitter and a Mall Safety Kit
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: [v.o.] 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.
