In "The Maternal Combustion", in the final Apartment 4A scene Beverly says that she always made Leonard earn her affection but realized from Sheldon that there's more than one way to raise a child.
But do you think it's a bit too late to fix any damage?
In this alternate scenario, Amy is in it too.
Mrs Cooper: I’m so glad that you and I were able to bury the hatchet.
Dr Hofstadter: Me, too. And I respect your right to your beliefs.
Mrs Cooper: And I will pray for you.
Leonard: Okay, Mom, Amy will get you back to your hotel.
Amy: Come on, Beverly. Let's go.
Dr Hofstadter: One moment. There’s something I need to say to you.
Leonard: Oh, really? Well, I don't think I'm interested.
Dr. Hofstadter: But it'll probably be good.
Leonard: Ugh, fine. Just say it and leave, please.
Dr Hofstadter: Leonard, I always made you earn my affection, but today I realized that there’s more than one way to raise a child.
Sheldon: I taught her that.
Dr Hofstadter: Therefore, I would like to initiate a new protocol wherein I shower you with unconditional love.
Leonard: Really, Mother? Well, you wasted your time! You had all those years when I was a little boy from when I was a toddler and up to the age of 10 and now it's too late to make things right! You can't change the past! (Turns his back angrily and crosses his arms)
Dr Hofstadter: Please, Leonard. Come to Mommy.
Sheldon: Come on, Leonard.
Penny: It’s okay, baby, go ahead.
(Leonard decides to do so. The hug happens)
Dr Hofstadter: Oh, my son.
Leonard (glumly): Oh, my mother.
Penny: Oh, my God.
