Does no one find it strange that soon after Billy Chambers reveals the president's affair that he dies? How did no one think to look for murder? The whole storyline just blows over, which no visible consequences.
It turns out by the end of the second season that Billy Chambers is not dead, and that he became The Mole known as "Albatross". It should be pointed out that the first season was only 7 episodes long and the people behind the show probably didn't know at the time that the show would get a second season. It could be chalked up to an Aborted Arc.
Olivia Pope doesn't do a background check on the strange man that's suddenly appeared in her life, and is an important military man with access to the president? Really?
If Mellie wants power so badly, why doesn't she just divorce Fitz and "dance on his ashes," as she threatened Cyrus she would do? She seemed pretty convinced that she'd be able to increase her political power if she did so.
There are several points throughout the second season that suggest that Mellie feels affection towards Fitz (after all they have been married for twenty years and have three kids together) and is angry at Liv stealing her husband not just because it would hurt her political power but because she is emotionally invested in their relationship. Also,if Mellie attempted to "dance on his ashes", Fitz would still be the President and so be able to carry out a massive PR campaign against Mellie, which she is threatened with in the last few episodes of the season.
In "Beltway Unbuckled", President Grant is unwilling to press Kyrgistan over a diplomat who murdered a blogger because he needed access to their airspace for an upcoming conflict in East Sudan. Which is nowhere near... Does Shonda Rhimes own a map?
Gladiators were slaves that fought for the amusement of the crowd and to make money for their owners. So why do two black people who think they're doing an important job use "gladiators in suits" to describe themselves?
