in this show，Underwood is a singularity. all rules don't apply to him. even the rule between reality and fiction： ONLY he can talk to the audience.
what happened in the very end of this episode is， Claire became ANOTHER singularity. (she looked at the camera)
i think in the next season， she will directly talk to the audience too. there is no more leading role or supporting role， there are only THEM, and this,i believe is also the meaning of the post of this season： Two Singularities.
（by the way，the post did a good job of misleading the audience，it made us think that this season was going to be Frank vs Claire.）
