There are often "fish storms" in tornado country. A funnel cloud will suck up water out of a lake, taking fish along with it, and then deposit them miles later. But I've never heard of this in relation to a snowstorm.

A native Californian would pronounce the "Al" as rhyming with "pal" rather than "all".

Agree. Also, there's an element of, "damn, we're going to be hearing about Kiernan Shipka for a long time."

Perhaps making your point, Shirley actually was featured in Episode 1.

As Sally said to Don later, "I'm so many people." I think she tossed off that line just to be cool to her friends. She may have resentments toward Betty, but I don't think they extend that far.
