It just seemed a little out of character of Darlene to have a fun lighthearted laugh with her sister so I wondered if Sara and Lecy did a little impromptu.
I wonder if it was an in-joke the writers slipped in or if they're just that good at acting they just ran with it. It's an out-of-character moment for both of them and they both did it well.
Interesting take. I never thought about it like that. Maybe? It does stick out as a scene that carries a certain amount of tension, but I always attributed that to a demonstration of their sisterliness despite their differences/strained relationship.
I have no idea. But that scene always felt off to me. I hate it.
The two of them trying to stifle giggles tells me they might have had part of it scripted and then they just carried on with the joke
