Since we got old Spock and Romulan baddies...do you think there's a chance we'll see a reunification?
Perhaps Nero is travelling back in time to prevent Spock from being born/seving in starfleet/something else entirely because they don't want the reunification to happen.
Then at the end, the Romulan Star Empire joins the United Federation of Planets.
