Zombie Kid - S1-E4
Continuity mistake: When gang-tae sits down to eat noodles with Moon-young, just as Moon-young says "Zombie Kid?", she is shown with chopsticks (with noodles in them) in her right hand and has the chopsticks pointed upwards. In the next shot, the chopsticks are suddenly pointed downwards (now back in the bowl). (00:18:15)
Factual error: Emily is in Paris when her boyfriend calls from Chicago and wakes her. She asks the time which he says is 7pm, and she says 3am in Paris, which cannot be. Central European Time is 6 hours ahead of NY and 7 from Chicago. 7 pm in Chicago would be 2 AM in Paris.
