John would probably be shocked at first. He'd be concerned about how Sherlock would handle being a father, given his rather detached nature. But then he'd be very supportive, offering practical advice like setting up a nursery. Mrs. Hudson would be over the moon. She'd start knitting baby clothes right away and would constantly be fussing over Molly, making sure she's eating well and resting enough.
Sherlock's homeless network might seem like an unlikely group to be involved, but they would actually be very helpful. They'd keep an eye on Molly when Sherlock was away on a case. They'd bring her little gifts they found on the street, like a small, unique trinket for the baby. And they'd be there to offer a different perspective on life, which would be quite refreshing for Molly during her pregnancy.
Mycroft might be more calculating. He'd see the potential implications for Sherlock's career and reputation. However, he'd also realize the importance of family and would secretly make arrangements to ensure their safety. Lestrade would be a bit awkward at first, not really knowing how to handle the situation, but he'd soon warm up and would probably offer to babysit from time to time.
Sherlock might also feel a sense of responsibility, even if the pregnancy wasn't his doing. Given his loyalty to his friends, he would probably try to be there for Molly. He could use his connections to ensure she has the best medical care available. And in the long run, this could be a turning point in his relationship with Molly, either bringing them closer together or causing some strain depending on how he handles the situation.
Their friends might be initially shocked. Some, like Alice, might be excited and start planning for the baby's future right away. Others, like Edward, could be more worried about the potential risks to Bella's life.
Her friends would likely be very protective. They might form a sort of guard around her, making sure she's safe at all times. Some of them would probably be excited about the new life coming into the world and start preparing things like a nursery or gathering supplies for the baby.
Their friends would probably be initially shocked. But then, most of them would be very supportive. Kara, for example, would be super excited and offer to help with anything from babysitting in the future to giving advice on super - powered babies if there are any implications related to that in the fanfic's universe.
Alya would probably be super excited and start planning everything from baby showers to future playdates. She'd be there for Marinette every step of the way, giving advice and support. Nino might be a bit more reserved at first but would soon warm up to the idea and be a great source of comfort for Adrien, like helping him pick out baby clothes or build nursery furniture.
Hermione would probably be super helpful. She'd offer all kinds of advice on everything from pregnancy care in the wizarding world to setting up a nursery with magic. Ron would be a bit more awkward at first, but he'd still be excited. He might joke around a bit to lighten the mood. Neville would be very kind and bring over some of his own home - grown magical plants that could be useful during the pregnancy, like plants that have calming properties or ones that can help with minor ailments.
Some of their friends might be worried at first. They know the dangerous lives that Natsu and Erza lead. But then, they would all come around and be very supportive. They could throw a big celebration for the pregnancy, and everyone would chip in to help make a comfortable space for the baby in the guild. There would be a sense of new hope and family spirit in the group.
Diane would probably be overjoyed. She's always been close to Meliodas and Elizabeth, and she would likely offer to protect them and help out in any way she can. Maybe she'd use her giant strength to build a special place for them to stay during the pregnancy.
The friends' reactions could also vary depending on their own personal experiences. If one of their friends has had a difficult pregnancy or lost a baby in the past, they might be more guarded in their excitement. They could offer more emotional support rather than just focusing on the happy aspects of the pregnancy, like Ayako who might be there to listen to Mai's fears and concerns throughout the pregnancy.
Their friends would likely be shocked at first. Happy for them, but also a bit worried. Erza, for example, would probably be very protective. She might start giving Lucy all sorts of advice on staying healthy and safe during the pregnancy. Gray might be a bit awkward around the whole situation at first, but would eventually warm up and offer his support in his own way, like helping Natsu with any odd jobs or tasks so he can focus on Lucy.
