One popular storyline could be about how they deal with the reactions from their friends and family. Their friends might be shocked at first but then become very supportive. Another could be them preparing for the baby, like shopping for baby clothes and setting up the nursery together. It could also involve them facing challenges in their relationship due to the pregnancy stress, but in the end, they grow stronger as a couple.
Some stories may focus on how Sam and Quinn's relationship changes during the pregnancy. They might have arguments about who will take care of the baby more, or how they will manage financially. However, they also have really sweet moments, like when Sam talks to the baby bump at night. There could be a part where they attend parenting classes together and meet other young couples in similar situations, which helps them feel less alone in this new journey.
I think Santana would be a great addition. She could be the sassy friend who gives them brutally honest advice. Also, Brittany. She might be really excited for them and offer some really unique and endearing ways to help with the pregnancy, like knitting baby booties in really strange colors. Puck could also be included. He might start out as a bit of a troublemaker, teasing Sam about it, but then turn into a really good support for them.
One popular storyline could be a magical or cursed situation that causes one of them to become pregnant against the normal laws of nature. For example, a spell gone wrong in a hunt that has unforeseen consequences. Another could involve some sort of alternate universe where male pregnancy is the norm and Sam and Dean have to navigate this new reality while still dealing with their usual hunting duties. And sometimes, it might be a really out - there concept where they are impregnated by some sort of otherworldly being as part of a deal or a plot to either save or destroy the world.
The plot could involve Quinn and Sam's relationship taking a new turn when they find out about the pregnancy. For example, they might have to deal with the reactions of their parents. Quinn's mother might be disappointed while Sam's parents could be more accepting. They'll also need to figure out how to balance school and the upcoming baby. And of course, there could be some sweet moments like when Sam feels the baby kick for the first time.
One idea could be that Quinn and Sam are high school sweethearts who find out they're pregnant unexpectedly. They face the initial shock and fear together, then decide to tell their families. Sam stands by Quinn throughout, and they start preparing for the baby's arrival, like painting the nursery and taking parenting classes. It could also involve how their friends react, some being supportive and others being judgmental at first.
Their relationship can grow deeper as they face the pregnancy together. They become more reliant on each other for emotional support. For example, Sam might hold Quinn when she has pregnancy - related mood swings or fears. They also start to communicate more openly about their future as a family.
Another idea is that the father of the baby is a mystery, and Harley goes on a journey to figure out who it is. Along the way, she discovers things about herself and her past relationships. This could involve her visiting old friends or foes and reminiscing about different parts of her life.
One possible storyline could be Harley Quinn adjusting to the idea of motherhood while still dealing with her chaotic life. Maybe she's trying to figure out how to raise a child in a world full of villains and heroes. Another could be her relationship with the father of the baby, whether it's the Joker or someone else, and how that dynamic changes during the pregnancy.
One possible storyline could be that Sam and Jack face challenges in their military careers while also dealing with the pregnancy. Maybe there are rules against their relationship in the military context, and they have to fight to be together and also ensure a safe and happy environment for the baby. For example, they might have to keep their relationship a secret for a while.
One of the most popular themes is the redemption of their relationship. After all the ups and downs in the show, fanfiction often explores how they can fix things between them. Another is the exploration of their musical connection, since music was such a big part of Glee.
One possible storyline could be about how Quinn and Puck deal with the reactions of their friends and family. For example, Quinn might be worried about her parents' response, while Puck could be concerned about how his bad - boy image will be affected. Another could be their struggle to balance school, their social lives, and impending parenthood. They might have to make sacrifices like giving up some of their extracurricular activities in Glee club to focus on preparing for the baby.
