Because Jessica is the best thing that ever happened to any of the Suits characters, Anita ultimately voted in Mike’s favor, and Mike will officially become an actual lawyer.
She didn’t seem to have any regrets about her decision to leave when she made her big exit in the Season 6 summer finale, but evidently Mike’s future in jeopardy was reason enough for her to come back to the Big Apple and save the day.
The show that began as the story of hotshot lawyer Harvey and his fraudulent genius protege Mike has been turned into something brand new now that Mike is a lawyer, and it’s all thanks to Jessica flying back to New York from her life (presumably) in Chicago.
