In season six, Piper decides that she wants to write a memoir about her time in prison. That fits with the show's inspiration, the book Orange Is the New Black by the real-life Piper Kerman. While the fictional Piper just had a prison wedding to Alex, the real Piper is still married to Larry Smith. It's unlikely the show would have the fictional Piper and Larry reunite, but it would be a full-circle moment for Larry to congratulate Piper on the book deal.
