How would my friends react?

Some friends were likely horrified. The Chris Watts case was so heinous. His actions of murdering his family were unimaginable. Friends might have initially been in disbelief, thinking that the person they knew couldn't be capable of such a thing. They could have felt a sense of betrayal as well, since they thought they knew him but he had this dark side.

Draco's Slytherin friends would be quite shocked. Some might shun him, thinking he's betraying the Slytherin ideals. However, a few might see the advantage of having a connection to Harry Potter. For example, if there are any threats to Slytherin as a whole, Harry's influence could be useful. So there would be a split in how Draco's Slytherin friends react.

Their friends would probably be very excited. Some might offer practical help like baby - sitting tips or giving them baby clothes. Others could be super emotional and start planning baby showers right away.

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.

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.

Harry and Ron would likely be very shocked and concerned. They know Fenrir is a dangerous werewolf, and they might not understand how Hermione got into this situation. They would probably try to persuade Hermione to leave Fenrir at first.

Their friends would probably be very excited at first. They might throw a surprise baby shower for Brian and Mia. Some friends could offer to help with things like setting up the nursery or giving them advice based on their own parenting experiences.

Hermione's friends from Hogwarts like Harry and Ron might be a bit shocked at first. Ron, in particular, might have some mixed feelings as he has had a bit of a competitive streak with Viktor in the past. But eventually, they would come around and support her. Viktor's friends from Durmstrang would probably be more accepting as they might respect his choice more blindly. They could be excited for him and offer their own unique magical gifts or knowledge for the upcoming baby.

Leonard would probably be really shocked at first. He's known Sheldon for so long and might not have expected him to become a father. Howard and Raj would likely be full of jokes and teasing, but also offer their support in their own goofy ways.

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.
