I think there’s also a non-Arlo interpretation: that Rita immediately started thinking of Edna as an innocent little girl and treated her as one (”here’s a snack, honey”)

Which comes back to the idea of Brooke either missing the innuendo inherent in the choice of such a phallic food, rather than something like a chocolate bar, or leaving it in despite seeing it, but not intending it.

I do suspect, though, that Edna missed it. What with her being virginal and all.

Or maybe Miss Hayworth wanted to see what she’d do with it.

You remember the story of Sherlock Holmes and Dr. Watson walking past three women who were sitting on a park bench eating bananas. “Good morning, Ladies,” said Holmes.

Watson:”I say, Holmes. Do you know those ladies?”

Holmes: “No, my dear Watson; I have never seen that nun, that prostitute or that newly-wedded bride in my life.”

Watson: “How on earth do you know what they are?”

Holmes: “By simple observation. Look: the nun is cutting the banana into small slices with a knife before eating it. The prostitute is trying to cram the entire thing into her mouth. And the newly-wedded bride is holding the banana in front of her mouth with her left hand while her right hand is behind her head pushing it down.”
