Korra Alone - S4-E2
Continuity mistake: There are several inconsistencies between the last scene of the previous episode and the one recounting it in this episode: 1) Korra is jumping up and down when she says "Is that all you got?" in the last episode, but in this one, she's standing still, 2) Korra collapses after the line "We have a winner!" is heard, instead of before like in the previous episode, 3) Korra's bag changes design, from a grey duffel bag to a green backpack.
Continuity mistake: Wei and Wing's belt buckles go from identical to being different in the scene where the Beifongs are talking to Kuvira.
Plot hole: Guards at a security checkpoint attack Varrick and Bolin, because a wanted poster identifies them as fugitive traitors. The problem is that poster cannot have been there. Varrick and Bolin escape in the previous episode (Battle of Zaofu) but are captured minutes afterwards. (So, no posters needed.) The next day, they escape again by blowing up their imprisoning train car. Their captor, Bataar, thinks they are dead. Indeed, Varrick intended to die. Later, Bataar is actually shown reporting them dead. One might argue that the poster wasn't a wanted poster, but one that warned people about the empire making an example of the traitors.This argument is too flawed: The empire had many examples already, some very high-profile. And a propaganda poster must be placed in plain sight, not in a security booth corner especially designated to let security guards compare the passing individuals. (00:14:00)
Continuity mistake: When Asami and her dad are talking when he's in the hummingbird he has black eyebrows, but when it zooms out his eyebrows are grey.
Answer: We do not see what happens. Avatar shows rarely have people killed on screen, so either he got away and was never seen again, or just died right there. As Amon was outed as a bender, he would not go back for his old boss.
