The season two finale of Paradise, titled "Exodus," revealed that Alex, played by Sterling K. Brown, is an AI and will Alex save the world or destroy it? The show's writers are now looking ahead to its renewed third season. The finale also raised several questions about the relationship between Sinatra (Julianne Nicholson) and Alex, who are played by Thomas Doherty. The writers also explained the quantum physics involved in the Alex-AI storyline and how they simplified it for actors so their minds wouldn't explode thinking about it. Hoberg, who co-wrote the finale, also explained that the series hired a quantum physics consultant and their theories were vetted by quantum physicists.
