Getting Even - S4-E3
Factual error: Ash gives Albert a slip of paper with Lily's home address, including a postcode of WC2E. That postcode is in Central London, but the house Albert then goes to is somewhere far more suburban, a long way from WC2. (00:50:21 - 00:55:22)
Continuity mistake: Shiro cuts Stacey's right cheek with his sword, drawing blood. However, in subsequent shots, Stacey's cheek is completely unmarked, and there is no sign of any cut or blood. (00:32:46 - 00:33:58)
Continuity mistake: When Danny and Stacey walk into the Human Resources office, a shot of the woman behind the desk shows the glass countertop has nothing on it. However, when Stacey spins the monitor around, a mouse suddenly appears in the next shot on the glass countertop. (00:30:05)
