The main characters travel back in time and interact with a man. When they return to their time, he finds a way to come back with them. He feels much happier in the current time, but might be causing trouble. He migh also be in love with a woman that he met in the current time period. This was probably on tv within the past ten years. It is either American or Canadian.
It’s an episode of Eureka where they went back to the 1940s and brought someone back with them. Thanks for reading my posts and trying to help,
