I finished watching last night Brooklyn Nine Nine and tonight's Gotham, so I decided to check out the Reigns interview when I saw that it was coming on. Heavily scripted for the softball questions, BUT...
They did finally give a bit of a "unique" backstory that he was missing since the Shield breakup. He has that "the WWE fed my family" thing going, where he was literally born into the WWE system, and now it's his time to be the man. It's not the best/most original thing, but maybe they can do something with it.
