The reason the third season was so disappointing was because they insisted on centering Piper's character despite the fact that she hear the most boring storylines and she the least dynamic actress in the cast. There are more than enough characters for Piper to be a de-facto side character and we aren't forced to indulge in her White tears anymore. With the new prisoners to (what will be) an overcrowded prison I'm hopeful that the writing crew will hire some people of color and people with disabilities (who actually make up the vast majority of the prison system) and have some freshness to the stale storylines we suffered through for the third season.
