There could be a friend who is initially shocked. Like Malia, who doesn't quite understand the whole concept of pregnancy and family yet. She might say some inappropriate things at first, but then slowly come around and become really fond of the idea of having a baby in the group, and start to look out for Lydia in her own unique way.
Some friends might be overjoyed. For instance, Stiles could be really excited and start making all kinds of plans for the baby shower. He might also be a bit overprotective, constantly checking in on Lydia and making sure she's taking care of herself.
Their friends might be initially shocked. Some of their more cautious friends could be worried about the implications of a child born to such powerful individuals. However, their closest friends would likely be very supportive and offer help in any way they can, like providing a safe place to stay or resources for the upcoming baby.
Well, Serena would probably be over the moon. She's always been close to both Dan and Blair and would see this as a wonderful union. She'd be there for Blair during the pregnancy, helping her with shopping for baby clothes and giving her advice. Nate, on the other hand, would be more practical. He'd offer to help Dan with any financial or housing arrangements they need to make for the baby. And then there are the more catty friends, like Penelope and Hazel, who might be jealous and make snide remarks about how Dan and Blair got pregnant so quickly, but deep down they're just envious of their relationship.
Some of her friends might be overjoyed and immediately start planning baby showers and buying cute baby gifts.
Ross would probably be really shocked and a bit jealous at first. He might have a hard time accepting it. Phoebe would be super excited and would probably offer to be like a spiritual guide for the baby. Chandler would make a lot of jokes about it, but deep down he'd be happy for them. Monica would be practical and start planning things like baby showers and making sure Rachel has all the right things for the pregnancy.
One friend might be a bit jealous at first, secretly wishing they were in Eve and Roarke's position. But overall, most of their friends would be very supportive. They would gather around, offer to help with things like setting up the nursery, and share their own experiences of pregnancy and parenting if they have any. There could also be a friend who is a bit of a worrywart and is constantly giving Eve advice on what she should and shouldn't do during the pregnancy.
Some friends might be shocked at first. Kurt could be overly dramatic, worrying about how this will change everything. Finn might be a bit jealous or concerned for Rachel. Quinn could have a complex reaction, since she has her own history with Puck. But overall, most of their friends would probably come around and offer support, like helping with baby preparations or just being there to listen.
Their friends are likely overjoyed at first. Fishlegs might be a bit of a nervous wreck, constantly worrying about Astrid's health and the well - being of the baby. He'd probably be reading every book he can find on dragon - rider pregnancies (if that's a thing in their world). Snotlout would probably make a bunch of inappropriate jokes at first, but deep down he's also excited. Ruffnut and Tuffnut would be their usual chaotic selves, but also show their support in their own unique ways, like bringing strange gifts they think the baby would like.
Some friends might be a bit worried, especially if Carlos and Jane are young or if there have been some problems in their relationship before. They could offer their support by being there for them during doctor visits and helping them get ready for the baby, like setting up the nursery.
Some of their friends from the Fire Nation, like Mai, could be hesitant. She might worry about the implications for the Fire Nation's future and Zuko's role as a leader. However, as time passes and she sees how much Zuko loves Katara and their unborn child, she becomes more accepting. On the other hand, the Water Tribe elders could have mixed reactions. Some might see it as a good sign of unity, while others might be concerned about cultural differences.
Their friends could have a wide range of reactions. Some might be overjoyed and offer lots of support, like bringing over baby clothes and offering to babysit in the future. Others might be a bit more skeptical, especially if Blaine and Rachel's relationship has been a bit rocky before. They could worry that the couple isn't ready for this big step.
