Hey, World! - S4-E16
Continuity mistake: After Gary says "it's part of the show" and turns to face the dragon, he lowers the microphone offscreen. Cut to the front, and it's up by his mouth again.
Factual error: The Legends are stranded in England and wait for a bus to London. However, the bus that pulls up is left-hand drive, when it should be a right-hand drive one.
Swan Thong - S5-E15
Continuity mistake: During the fight scene near the end when Marie Antoinette tries to stab Mick he grabs her wrist, it keeps changing which wrist he is holding. When it shows from her point of view looking down he has her right, but from his point of view looking up he is holding her left.
Chosen answer: Black Canary, Spartan, Wild Dog, and Ragman.
