That brings us to the Underwoods.
Thus, at the top of Chapter 64, Frank pushes Catherine Durant down a flight of stairs.
Shes useless to Frank now, preparing to testify before the committee and showing no sign of backing down.

Chapter 64 goes further and looks at just how calculated this downfall has been.
Doug doesnt take the news well who would have thought?
realizing that hes going to have to giveeverythingto the Underwoods.
Hes always been loyal, but is this too far for him?
Its unclear at the moment.
On the one hand, he seems aghast at the idea of taking the fall for Zoes murder.
But, theres more.
Is loyal, faithful Doug the leak?
Is he sendingeverythingto Tom?
Surely the finale will provide some clarity.
Frank knows it, too.
Davis says the same to Mark Usher, convincing him that Claire is the future, not Frank.
He left a manuscript of his book in the house for Claire to find.
If the book goes to print, thats it for the Underwoods.
So, Claire does what she has to do (in her mind, anyway).
She has Mark set up a meeting in his house with Yates.
Their relationship is kind of complicated.
As actorPaul Sparks puts it to EW, Yates wants Claire to choose bedroom Claire over politician Claire.
Sure enough, Claire makes her choice.
With migraine medicine given to her by Jane, she poisons Yates.
Its truly a delightfully ludicrous death.
Thats not the only death in this episode though, even if the following one is more metaphorical.
As Chapter 64 comes to an end, Frank has agreed to testify before the committee.
This being Frank Underwood and all, he uses the opportunity to twist things in his and Claires favor.
(So much for TV drama being escapist!)
Is this truly the endof Frank Underwood as president?
Does this flush the way for Claire?
Will Toms investigation bear more evidence, and will it come from Doug?
