Goosebumps Season 1 Episode 3

While at the Halloween party, James accidentally hits his head on a cuckoo clock and discovers that when he tries to leave the house, he gets stuck in a time loop. He decides to use this opportunity to woo another boy named Sam and succeeds.

James turns off the cuckoo clock and is now able to leave. The next day, James learns that every attempt to leave the house created a duplicate. All the "Dupes" team up and capture James, trapping him in his family's mines. The Dupes begin to ruin James' life, but Isabella informs Isaiah and Margot of what is going on. They manage to locate and find the real James, destroying the rest of the Dupes. Isabella reveals to them she was the monster Margot and Isaiah saved Lucas from, and they realize that it all began at the Biddle house.

They question Nora on what she knows, and she implies that Margot's mother has the answers they seek. Margot calls her mother Sarah, who is in Seattle, and she tells them not to trust any of the adults. A surviving Dupe, revealed to have been working for Bratt all along, retrieves for him a suitcase. Finding out that it is empty, Bratt/Harold lashes out and destroys the Dupe, angrily asking where his "friend" is.
