Buona Sera, Mr. Campbell: Part 1 - S7-E6
Revealing mistake: After the younger bad guy delivers Amanda the cast iron skillet with fried eggs, he turns to leave, and she hits him over the head with it, knocking him unconscious. She then escapes through the window and older bad guy runs after her, and she hides in the bushes. A moment later all clear, she runs the opposite direction and straight into younger bad guy, who has somehow miraculously 'recovered' from getting hit over the head with a cast iron skillet.

Buona Sera, Mr. Campbell: Part 1 - S7-E6
Continuity mistake: When Amanda is tied up lying face down on the floor, the next moment cuts to her using broken glass to cut the ties to free herself and her hands get all bloodied in the process. Yet after she frees herself then grabs her coat, and runs out onto the porch, her hands are suddenly clean.
