The OA left many questions to be answered behind with the first season finale and was highly appreciated by the audience. The OA's second season is quite chaotic and confusing.
In the first season, all the theories that came to mind were refuted and an unexpected scenario was written. The OA, which is the most watched series at a time in Netflix, arouses your curiosity with its unexpected plot and never lets you get away with it. In the second season of the series, you understand that the first season is an impressive story in its own right, and it is a preparation for the complex concepts that will be put ahead. In the first season, we find ourselves in a more complex world while watching the life and death issues after death; multiple universe theories and when we die we wake up in one of the parallel universes. In the first season, while watching the life and death issues after death, and in the second season we find ourselves in a more complex world; multiple universe theories and when we die we wake up in one of the parallel universes.
The second season brings together the universe we remembered from the first season and the universe where Prairie wakes up as Nina Azarova after being shot in the school. So the characters we know from the first season are the same but the events developed with small differences. This caused Prairie to wake up in a universe where Nina Azarova's father did not die and she was not adopted. In this universe, the main tasks of Prairie are to find Homer, in which she has come through difficult ways to integrate with Nina Azarova and to be together.
The fact that the first season ended with Homer's name was a clue to us. Yes, Prairie finds Homer in this new universe, but in a completely different way: Homer is not aware of anything in this new universe. In spite of Prairie's efforts, Homer's recollection of his past life is entirely through the integration of Prairie with Nina Azarova. According to Elodie, one of the new characters in the series, the lives of Prairie, Homer and Hap are interdependent. They will find each other in whatever universe they are. This is the truth that prepares us for the third season. In the final episode, we are moving to a completely different dimension. While this dimension answers the question of what's behind the mosaic glass in the season, it also prepares us for developments in the third season. I hope that future seasons will be enriched by adding new layers.
