Time Travel Episode

Basically, an episode whose plot revolves around time travel, whether it's to the future or to the past. Maybe the villain wants to remove the hero from history. Maybe the resident Gadgeteer Genius wants to see the tech of the future.

Groundhog Day Loops don't really qualify, since in that case the time travel is reset at the end.

In some cases, the time travel is a Framing Device for a Recap Episode, or for giving a character's origins.

  • Murdoch Mysteries: The plot of "Twentieth Century Murdoch" revolves around a time machine. A man gets involved in a couple of incidents (a suicide attempt and a shooting) and claims he went to the future, saw the events and went back to intervene. He also wants to save a boy from being trampled by horses, and Constables Crabtree and Higgins later go to the street intersection and witness events unfold just as the man said they would. Soon word gets around, and people are lining up and paying for trips to the future. Murdoch is initially skeptical despite the testimony of other paying travelers, but when the scientist suggests he try the device, Murdoch takes him up on the offer. What Murdoch sees (including himself married to Julia in 1912 and an eight year old boy who introduces himself as "William Murdoch Junior") changes his mind, and he's soon closeted in his office with the scientist, with his blackboard covered in equations. It turns out the machine uses electricity to make people more suggestible and they have "visions" of the future based on what the scientist tells them they're seeing and the scientist is using the money to finance a cryogenic chamber for his half-brother Dr. Roberts, who has Huntington's disease.
