"You look happy," Alba Villanueva tells her granddaughter Jane as she twirls in a new blue sundress one morning. The comment seems to catch Jane by surprise — and just five short episodes after a deadly serious revelation, it catches viewers by surprise, too. Is Jane happy? About halfway through its third season, The CW's high-energy telenovela Jane the Virgin — known for its flashy, delightfully farfetched melodrama (pseudo-incestuous lesbian crime lords, accidental artificial inseminations, and the like) — took an unusually sharp, unusually dark turn. This is a show that capitalizes on outlandish plot arcs specifically designed to make you roll your eyes back into their sockets (the story centers on a young Catholic woman, Jane Gloriana Villanueva, who's spent 23 years saving sex for marriage but then gets pregnant due to a medical error during a routine gynecological visit), so you'd think no twist could really catch the audience by genuine surprise.
