The OA Season 2: 11 Big Questions After The New Trailer
8. What Are The Story Group Doing?
With the trailer largely focused on Nina/Prairie/The OA, there's not a huge deal to glean about the story group, made up of "BBA and the boys" as referred to here. They're still together, at least at one point, but there are also various shots of them in differing states of distress.
The synopsis offered up doesn't give much more, simply stating: "Meanwhile, back in the first dimension, BBA, Angie and the boys find themselves on a journey to understand the truth behind OA’s story and the incredible realities she described."
Again, it just opens up more questions (which is the point). They're believing what OA told them, which means we should see them attempting to learn more about what happened to her and the movements, and perhaps the universe too - but could also lead them into danger.
