Clark might be initially shocked but then very supportive. He would probably offer his help in any way he could, given his own experiences with dealing with extraordinary situations. Lois might be a bit more outspoken, giving Chloe advice on motherhood and also teasing Oliver about becoming a dad. Tess could see it as an opportunity to use their situation to her advantage in some way, but eventually come around to being supportive.
Dan would probably be shocked at first. He has a complex relationship with both Lucifer and Chloe. But he would also be concerned for Chloe's well - being and the future of the baby. He might offer his help in more practical ways, like making sure Chloe is safe during her detective work. Ella would be super excited. She's always positive and would probably start knitting baby clothes right away and be full of ideas for baby names.
Harry would probably be shocked at first but then very supportive. He'd offer his help and protection, knowing how important Hermione is to him and how much she's been through. Ron might be a bit more hesitant, having his own complicated feelings about Hermione, but in the end, he'd come around and be there for her. Ginny would be excited and would start giving Hermione all kinds of advice about motherhood. Neville might bring over some magical plants that are good for a pregnant woman's health. Luna would say some very unique and wise things about the new life that's coming and how it's connected to the magical universe.
There could be a fanfic where Chloe gets pregnant by accident with Oliver in Smallville. At first, they are both shocked and a bit scared. But as time goes on, they start to see it as a new beginning. Oliver might have to face his own fears about being a father, while Chloe could be worried about how her pregnancy will affect her work or her friendships in Smallville. Eventually, they grow closer as they anticipate the arrival of their baby.
Maybe a story where they discover the pregnancy in an unexpected way. Like, they were on a mission together and Chloe starts feeling unwell. After some tests, they find out she's pregnant. Then it could be about how they break the news to their friends and family in Smallville. Lois might be overly excited and Clark could offer his support in a very Clark - like, selfless way.
Their friends could be overjoyed. Diggle might offer his support and protection, as he has always been a loyal friend. Thea could be excited about becoming an aunt and start planning all kinds of baby - related things. Curtis might use his tech skills to create some amazing baby gadgets for them.
One possible plot could be that they face challenges from their families. Maybe Oliver's family has certain expectations for him and the baby, and Chloe's family is worried about her future. Another aspect could be how they balance their superhero/vigilante activities with preparing for the baby.
One idea could be that they face challenges in their relationship due to the unexpected pregnancy. For example, Oliver might worry about how his vigilante life could affect the baby and Chloe. Another could be that they go on a journey to find a safe place for their family, away from the threats in Smallville. They could also have to deal with the reactions of their friends and family, some of whom might not be as supportive as they hoped.
Definitely Clark. He has always been a central figure in Smallville. His friendship with Chloe and his acquaintance with Oliver make him a natural addition. He could offer his super - strength to help protect Chloe during her pregnancy if needed, and also give Oliver some advice on being a good partner and father based on his own values.
Some of their friends would be immediately supportive. They would offer to help with whatever Laurel and Oliver need, whether it's setting up a nursery or just being there for emotional support. Others might be more skeptical. For example, some of Oliver's old friends from his playboy days might not believe he's ready to be a father. But overall, the reactions of their friends would play a big role in how Oliver and Laurel navigate the pregnancy in the fanfiction.
The plot could be that Chloe and Oliver have a secret relationship in Smallville. One day, Chloe realizes she's pregnant. They then have to decide whether to keep it a secret or tell their friends. Their friends in Smallville, like Clark, might have different reactions. Some could be supportive, while others might be skeptical about their relationship and the pregnancy. As the pregnancy progresses, Oliver and Chloe face challenges such as dealing with Chloe's health issues during pregnancy and preparing for the baby's arrival.
