...And Finally: Black Bolt - S1-E8
Continuity mistake: Maximus asks Black Bolt who the bunker was designed to survive an attack from. Black Bolt signs back that hope you never have to learn who. Bolt's head is turned towards the right, while he's looking left, giving Maximus the side eye. Then in the next shot, Bolt is looking directly at Maximus. (00:37:25)
Behold... The Inhumans - S1-E1
Character mistake: When Hunter One and his men are trying to sneak up on Gorgon in the jungle from behind them, Gorgon chuckles and says, "Never approach downwind, dumbass." He then proceeds to counterattack them. This implies he smelled them coming with the wind. However, this is backwards, as they would need to approach from upwind for their scent to carry to Gorgon. Approaching from downwind would be correct. So he should have said, "Never approach from upwind, dumbass." (00:33:35)
