Dark Matter · Season 2

Jason Dessen, a college physics professor, was abducted by a masked man, who was revealed to be another version of himself, Jason2. Jason1 found himself in a laboratory facility, Velocity Labs, where he met psychiatrist Amanda Lucas and Velocity CEO Leighton Vance. He escaped and returned home, only to discover that his life was different, with no sign of his wife Daniela and son Charlie. Jason2 had taken his place in Jason1's life and was living with Daniela and Charlie. As Jason1 tried to make sense of his situation, he learned that he was a world-renowned physicist in this reality, and that Jason2 had discovered a means to travel between dimensions using a metal box and a chemical compound. Jason1 agreed to work with Velocity, claiming he wanted to regain his memories, and studied Jason2's research. He and Amanda used the box to travel to different realities, but found themselves in desolate and ruined worlds. Jason1 and Amanda's journey through the multiverse continued, with them visiting various worlds, including one where a lab employee, Blair, resided. They eventually found a world that was similar to Jason1's, but not identical. Jason1 attempted to write a description of his world to focus his mind and better the chances of finding his reality. Meanwhile, Jason2 was using the box to manipulate events in Jason1's world, including replacing Ryan with another version from a different world. Jason1 eventually succeeded in returning to his own reality using his last ampoule. However, he soon discovered that every decision he made while inside the box had created another Jason, and that these alternate Jasons were now in his world. Jason1 reunited with Daniela and Charlie, but they were forced to flee from the other Jasons. The family took refuge at a holiday home, where they discovered that the other Jasons were attempting to decide which one would stay with Daniela and Charlie. In the end, Jason1 and his family escaped the other Jasons and made their way to the box's location, where they found a crowd of Jasons. The Jasons eventually decided to let them go, and the Dessens chose a doorway to escape. Jason2 left a box of ampoules and an audio recording, apologizing for his actions. The season ended with the Dessens escaping into a new reality, while Leighton from Jason1's world entered the box, and Blair2 left the world where she met Jason1 and Amanda.
