POP CULTURE THAT LIST APPERS SEEM TO KNOW TONS ABOUT (AND I DON'T)

Mostly TV. I know I will miss some so please share yours.
  1. Hamilton (the musical)
    I am clearly missing so much comedy
  2. Pretty Little Liars
    There is a mysterious "A" who maybe has been identified?
  3. Grey's Anatomy
    I have watched the candle scene and the "pick me" scene; the latter only because someone on ListApp refed it.
  4. Vampire Diaries
    That guy from Lost is on it and there's a love triangle, but I think (spoiler) one of them died?
