For all that is said about rape on television — it’s gratuitous, it’s unnecessary — we can at least agree that rape on television exists. Sure, TV features plenty of rape scenes used as mere plot devices: Anna Bates is raped on "Downton Abbey" (which builds tension in an otherwise happy marriage), Mellie Grant is raped by her father-in-law on "Scandal" (which shows she’s not just power hungry, but that she’s wounded).
