IS JEAN- #NancyDrewWAIT, WHAT? IS JEAN- #NancyDrewNancy Drew on The CW: Jean's pregnancy drives internet berserkWhile the latest episode of Nancy Drew season 4, titled The Sinner's Sacrifice, had its fair share of supernatural plotholes, one particular story came completely out of the blue; Jean was shown pregnant with Carson Drew's child.Jean was seen visiting a hospital. When she bumped into Nancy on her way, she tried her best to cover the truth. However, Nancy was no fool; she knew something was not right instantly but instead of confronting Jean, she chose to ignore it. The protagonist had massive problems of her own and didn't have to think about the baby, who was supposedly her half-brother.Finally, Jean revealed the news to everyone at the Seder. Carson was initially shocked to learn about it but he too was happy about the situation. While most fans were shocked by this particular storyline, many had predicted for quite a while that Jean was pregnant. This is how they reacted to the news on Twitter:kenz🌻 nace angst era@starcrossednaceJean’s def pregnant lol #NancyDrewJean’s def pregnant lol #NancyDrewem@nancyscompassguys this photo really was about nancy finding out jean is pregnant we were really on it this week #nancydrew pic.twitter.com/kNvg6SZ2bP152guys this photo really was about nancy finding out jean is pregnant we were really on it this week #nancydrew pic.twitter.com/kNvg6SZ2bPcarrie saw barbie.@addisonsdrewI knew Jean was pregnant! #NancyDrewI knew Jean was pregnant! #NancyDrewStarryMag@StarryMagJean: I’m pregnant.

While some didn't mind this plot, many were skeptical and called the entire thing unnecessary at this point in time. There is a lot going on with the main characters and emphasis on Carson and Jean is not something everyone was onboard with.Some fans liked the lead-up to the announcement of the pregnancy over the actual news. They thought that Carson's attitude and behavior were hilarious and cringy at the same time.Nancy Drew's synopsisAccording to Rotten Tomatoes, the synopsis of the show reads as:"Nancy Drew is a brilliant teen detective whose sense of self had come from solving mysteries in her hometown of Horseshoe Bay, Maine -- until her mother's untimely death derails Nancy's college plans.
