[Spoilers up to the end of "House of Cards" Season 3 above and below.]
In the last "House of Cards" teaser, we saw a bouquet of flowers on the subway track where Zoe Barnes (Kate Mara) was shoved to her death in Season 2. Then there was a slow pan up to a campaign poster asking you to vote for her killer, Frank Underwood (Kevin Spacey), so he could get "America back on track." Get it? "On track" like getting the country in line, but also on a track like a subway track? Do you get it? Yeah, you got it.
So, considering the callback to past secrets from Season 2, it should come as no surprise the latest teaser hints at a memorable image from Season 3. Watch the new spot above, and then feel free to check out a little article I wrote titled, "Before ‘House of Cards’ Season 4, We Need to Talk About Doug."
"House of Cards" Season 4 premieres March 4, with all episodes exclusively streaming via Netflix.
