Blanche and Dorothy and Rose and Sophia. Donatello and Leonardo and Michelangelo and Raphael. Max and Khadijah and Synclaire and Regine. Samantha and Carrie and Charlotte and Miranda. The Power of Four (those foursomes were from The Golden Girls, Teenage Mutant Ninja Turtles, Living Single and Sex and the City, respectively) is a well worn television trope. For one thing, it makes it incredibly easy for TV writers to format “Which X Show Character Are YOU?” quizzes, and for another, it’s the perfect number for audiences to latch onto and identify with. It allows for interesting mixes – each relationship reveals further insight into the characters, and allows for more nuanced inferences to be written for, and understood by audiences. It’s a magic TV number.
Whatever permutations the four take on, there is always a “hub person” ie the character around whom the others revolve. The three are mere satellites – interesting and worthy of study, sure – but all working around the main event, the fully formed planet that brings them all together. So that’s why Sex and the City’s Carrie Bradshaw was the only one who “couldn’t help but wonder”. It’s why Sarah Jessica Parker won the Golden Globe for Best Actress, while the others were nominated in the “Supporting Actress” category (only Kim Cattrall ever won). And even when all four of the leads won Emmys in the “Lead Actress” category, as with The Golden Girls, you knew in your gut that Dorothy Zbornak (Bea Arthur) was the show’s centre, just as Khadijah James (Queen Latifah) was the glue that kept the the girls together in Living Single.
