And They Were Enemies - S2-E10
Continuity mistake: The moment Madame Kali drops down dead, killed by werewolf Chandler, she's still wrinkled and old. Later on in that scene, though, when the monster runs off, her skin is all nice and smooth again. (00:19:10 - 00:20:05)
Continuity mistake: Dr. Seward is attacked by Brownfield. She hits him on the head with a heavy ashtray. He falls on the floor. First you see his body facing left. In the next shot, his body is facing right.
