This is...haven't a clue, but I'm guessing a daughter of Em. I'm also thinking that perhaps Fern is a daughter of Em. And it's slightly interesting that this woman is wearing a piece of fabric around her neck with stripes. Basically looks to be the same fabric Em is wearing.
"Oh mother dear, please let me have that excess fabric from your blouse. I will wear it as a tie.""Yes, of course... ummm...what was your name again?"
And I can tell you there is a third person wearing stripes. Possibly more of the same fabric, though it's more difficult to see. That is the person who will force a guffaw from you. A quiet guffaw followed by, "I waited this long for this? It's nothing more than a Seinfeld episode!"
