Continuity mistake: Ernie told Marissa about a mission that she was supposedly involved in before Ernie knew that KC faked the memory spray.
Suggested correction: This doesn't happen.
Continuity mistake: On the school dance KC takes out her earrings and lays them on the table, but when she is locked in the A/V room she has her earrings on. (00:22:17 - 00:23:24)
K.C. Undercover: The Final Chapter - S3-E24
Continuity mistake: When KC loses her phone you can see Ernie texts her saying that Amy is the mask, but he only gets the call from his parents saying that that Amy is the mask after that.
Suggested correction: This never happened. Ernie's text read "Bishops are in custody. Safe to break the news to Amy." Kira's text is the one that said Amy was The Mask.
