The Night the Dragon Screamed - S1-E17
Continuity mistake: After West saves the man from falling into the spiked pit, they walk to leave but a trap door opens, and they fall into the water. As they get onto the pier, both of them are soaking wet and have wet hair. They crawl out, sit, and start talking. The close-up of their faces, while they talk, shows that both of them now have dry hair.
