Time Fugitives: Part 1 - S2-E7
Continuity mistake: When the quarantine sign is being stapled to the door, it is black and yellow striped, with an orange stripe running the opposite direction, and "Quarantine" written on the orange part. When the mob is trying to get into the building, the sign is now gray with a single yellowish-gray stripe running diagonally across it, and no writing. (00:10:14 - 00:10:44)
