Sandra in the car with a crossbow, swim queen Shauna below in scuba gear saves both Grote A and Grote Beate. With Beate’s makeup washed off there’s a classic “I don’t know which one to shoot” moment (which makes no sense at all because they’re wearing different clothes but I’m spitballing here) and that tattoo Lottie got in Scotland (which I’m guessing is of a literal Chekov’s gun) is the identifying factor. Case closed, justice served, they all go out for ice cream and get ready for “The Case of Really, Really Apologizing to Dean.”
