Former FBI Director James Comey's Senate hearing on Scarlett Fay ArchivesThursday had all the appearances of must-see TV: A big lead up, dramatic characters, and potentially game-changing plot twists.

All it was missing was the benefit of actually being a TV show, but Frank Underwood would never let that stop him.

The official House of CardsTwitter account tweeted only one thing during the Comey hearing, and it was perfect.

What's Frank thinking? Is he annoyed? Satisfied? Amused? Is he telling America "I told you so" in Kevin Spacey's wiley drawl? Is he looking at us? Is he looking at Comey? Is he trying to silently shut down Marco Rubio?

This is shaping up to be one hell of a cliffhanger.
