I want to back up for a sec with Marcia Roy, after some more thought.
There is this anti-Semitic narrative that Jewish Americans have dual allegiance.
But to be clear, I don't think that's what this is. For one, Marcia is non-Jewish Lebanese, and her American citizenship is unclear.
To further solidify that Marcia was hinted as being a spy for the Israeli military, the person she is based on, Wendi Murdoch, is also suspected as being a spy!
It all works too well.
