In 4B:

*bringgg* *bringg*

Sheldon: Oh who is it now?! 

You know I hate phone calls

oh it's my MOTHER!!

Mary: Hi Shelly! How are you?

Sheldon: I am good how are you doing?

Mary: Ohh Shelly, so good to hear from you. Anyway, I was calling to let you know that Alfred and I are getting married

Sheldon: *crickets* and hangs up 

Mary: Shelly!

Mary:  Looks like the call got interrupted

Later that day:

Sheldon: Amy, my mom called me to tell me she's getting married to Alfred

Amy: That is great news! They will make a great couple. It's been a while since we last saw them

Sheldon: It's been three years and 2 months. What have they been doing all this time? Don't they owe US an explanation to their disappearance

Amy: No they DON'T, Sheldon!

Sheldon: I still don't understand why she never bothered to tell us about her plans to get married. It's like she didn't trust us with her secrets. And why did she wait for so long to get married? It doesn't make any sense to me.

Amy: Sheldon, she has her own life, you know. She doesn't owe us anything. Plus, maybe she was just nervous about telling us. We can all get nervous about things sometimes. The main thing is she's happy, and we get to celebrate her happiness with her.

In 4A:Amy: Leonard, Penny, Mary and Alfred are getting married

Penny: Yeah Alfred called us telling us her good news, she said we're all invited 

Amy: Let's text the others

Pastor: Alfred Hofstader do you take Mary Tucker Cooper to be your lawfully wedded wife, to have and to hold from this day forward, for better, for worse, for richer, for poorer, in sickness and in health, to love and to cherish, till death you do part?
