Long before she met Nick's mother, Betty asked Nick what his mom's name was. The conversation went pretty much like this.
"Nick, what's your mom's name?"
"Oh! Like the sled!"
She says this definitively, confidently.
He blinks, cocks his head. "Like the herb?"
"Yes. And the sled."
He has no idea what she's talking about. And she is waiting for him to get it.
I decide to help out.
