* The subway murder had so many variables, how could (because I don't know how to block something out for spoilers, I'll just say) the murderer know that they would have been followed by the murderee behind the fence out of sight entirely? How would the murderer have known the timing for the train, and how did he go through the metro gates undetected. Surely a man with sunglasses and a mask appearing when a reporter died would give the police something.
* In the first ep, why was it a humongous gotcha moment that Underwood was checking Zoe Barnes out? That isn't really enough dirt on someone to blackmail them into anything.
** ''Any'' picture of an older, married politician appearing to leer at a young woman who is clearly wearing a thong would get some attention, even if it was only with the more gossipy newspapers. With Frank's ambitions, it's definitely not the kind of headlines he needed at that moment. Plus, Zoe's determination to see him likely roused his curiosity and he let her in just to see why she would go to such lengths for a private meeting.
* Why didn't Peter Russo confide into his girlfriend in Chapter 4 that he was being blackmailed when she was basically on her way out the door. She was on her way out the door anyway
* So... in the first episode, DID SHE lick his balls?
* How would Russo's death be thought a suicide if he was sitting in the passenger seat of the car?
** With all the alcohol in his bloodstream and no sign of anyone else there. The Police would probably draw the conclusion, That Russo had left his engine running and switched seats to get comfortable. Or had got in the wrong side turned the key from there.
*** Which we saw he could easily do. The car was one of those where you just push a button, and Frank easily forced Peter's hand on to the button.
*** I have that same car, and the engine won't start if you aren't pressing the brake.
*** Frank [[BlatantLies explained]] to Zoe that the passenger door was open and that Russo was halfway out, having changed his mind but losing consciousness and dying before he could escape the fumes.
* Underwood meticulously wipes away all of his fingerprints from the crime scene, but he's also trying to make it look like a suicide. If the police dusted the car for fingerprints, wouldn't they notice that the door handles and steering wheel had been wiped? That would be a big indicator for murder.
** Depends if they even bothered dusting after the autopsy. Plus there's no obvious signs of a struggle or forced entry. You have a drunk and depressed senator in one hand. In his car, in his garage filled with carbon-dioxide in the other. Plus the paramedics probably contaminated the crime scene trying to get him out too.
*** You'd think the death of someone as important as a Congressman would at least trigger an automatic investigation, no matter how plausible suicide is.
*** It likely would, if the police commissioner was not indirectly linked to his death. The commissioner has every reason to downplay what happened as a suicide, because the moment a ''murder'' investigation is opened, its only going to lead back to him releasing Russo from custody.
*** It would have to take a lot of pull in higher places than DCPD. The death of a congressman would be under FBI jurisdiction.
* The Peachoid subplot. Am I the only one with thinks Underwood getting dragged into it seems off? The teenager who died got into that crash because she was texting while driving. Not to sound heartless, but that's her own fault. It's a stretch for a congressman that just kept it up to be blamed.
** Note Frank's mood throughout this episode: Frustrated. Not angry. He knows he can solve this in the minimum amount of time. His rival and opponent down there, is just using this as political ammunition to score cheap points, if he can drag it out long enough. The point isn't the Peachoid. Its showing (and us learning about) Frank in his home constituency and his attitudes and actions whilst there. Aloof, annoyed and viewing it as a step-back from dealing with bigger things. Like the military school episode, we find out a bit more about how Frank became Frank.
* Why did Walker rescind his pardon offer from Tusk?
** Frank convinced the president that he could whip the votes away from impeachment. Walker had to call off having Tusk confess or he'd lose Frank, and with Frank his only shot at not being impeached and losing his presidency.
* 'Gay girl meets future girlfriend while out recruiting for her cult-ish church.' The first part of that sentence doesn't fit with the last part of that sentence.
** Whether or not "cult-ish" is a fair description of the church, your Headscratcher assumes all Christians are anti-gay. [[http://en.wikipedia.org/wiki/LGBT-affirming_Christian_denominations They are not.]]
** I don't think the church was meant to be read as cultish once it was shown. Instead, I think it was meant to come across as a non-denominational liberal church more concerned with teaching "Jesus/God is love" and "acceptance of all." I think it was suppose to be a non-judgmental community environment for Rachel.
* Why wouldn't Frank immediately guess that Claire had went to Adam when she got mad at him and left? They were open about their outside dalliances and he had to know that she wouldn't be mad enough to be anything less than discreet and wouldn't cause a scene by completely disappearing. Adam, who knew he had to keep their relationship low profile, would seem like the obvious place for her to go with exception of maybe her parents if they were still alive. Was Frank just testing Meechum's discretion and ability to track down people (or find someone who could)?
