Legends (1) - S1-E16
Continuity mistake: When we first see Music Master's car, it's mostly in the street. In the next shot, more than half of it is on the sidewalk. And then, when the cops show up, it's nowhere to be seen even though it was parked in front of the stairs.
Chosen answer: In this series, Hal Jordan never became Green Lantern. Kyle Rayner did instead. John Stewart is Rayner's partner and serves as Green Lantern in the Justice League.
