Leonard: Uh, Wyatt, we need to talk.
Wyatt: Sure. What's up?
Leonard: I want you to back off. You know? If Penny and I don't have kids, that's between us. So you need to stay out of it.
Penny: Oh, Leonard, it's okay. We talked. We're good.
Leonard: Oh. Okay, you could've stopped me sooner.
Penny: Could've let you go longer.
