This is Sci-Fi about alternate universes created with every life choice we make. What if we had made a different choice? There's a universe for that choice.
This series was made in Barcelona, Spain and as such uses the Catalonia dialect of Spanish. Since I don't speak Spanish I tried different ways of viewing the series. I personally prefer the English overdub without subtitles, but every option is available. You could listen to the original Catalan Spanish with English subtitles, but I find the subtitles inaccurate. In any case, this series is absolutely excellent for any Sci-Fi fans who happen to also be hopeless romantics.
Episode 9 - After nearly getting run over... by himself, Eduard returns to his universe to find Dr. Everest in the hospital dying. He comforts her and goes home. Later, with Oscar and Clara, he tells them about Dr. Everest and they think he's crazy. He takes them to the hospital but she's gone and no one there knows anything. He goes to her home and the guard prevents him from going in, then tells Oscar and Clara that he's never seen Eduard before. He takes them to the shop where the portal is and it's abandoned with a mattress on the ground. Now they realize that he's been sleeping in the empty shop all these times he has disappeared.
When they take him home, his father in law tells him a story about regrets. He regrets letting Elisa choose to study arts instead of science. But he encourages Eduard that someday he will be able to go on living. He says that even he has begun living again; seeing a woman again since his wife died and shows him a picture of Dr. Everest. Eduard freaks out and goes to the train bridge where he finds Dr. Everest. He makes her activate the portal and asks that she send him to a universe where Elisa chooses to study science instead of the arts. He goes to a universe in the future where he is in Sweden and gets a mind-bending twist.
