Absolution - S3-E21
Continuity mistake: In the hangar, Simmons unlocks the security door so Fitz can escape the primitives. The control panel changes from a red SHIELD logo reading "RESTRICTED AREA" to blue reading "CLEARED," indicating the door is open. However, moments later while Fitz is fighting the primitives with a fire extinguisher, the door remains open even though the panel shows red and "RESTRICTED" again, then briefly turns blue before switching back to red as it closes.
