Final Exam - S1-E1
Deliberate mistake: Cyborg, Starfire, Raven and Beast Boy are kicked out of the Tower by the HIVE, and the trio watches them from the Operations/Main Living room panorama window. But whenever Jinx, Gizmo and Mammoth are seen (before they send in the tidal wave), the same window is on their right-hand side, whereas there should be a solid wall separating Ops from the side wings.
Chosen answer: No, she is not.
