They could have a friend named Lily who is always there to offer practical advice on taking care of the baby, like the best ways to soothe a crying infant or how to choose the right baby products.
There might be a neighbor, Mrs. Green. She's an elderly woman who has raised several children herself. She becomes like a grandmother figure to Sadie and Walt's baby. She offers her wisdom, like how to deal with the baby's first cold, and she sometimes babysits when Sadie and Walt need a break.
One possible plot could be that Sadie and Walt face challenges in adjusting to having a new baby. Maybe they struggle with lack of sleep and balancing their relationship while taking care of the infant. They could also have different ideas on how to raise the baby, which causes some minor conflicts but ultimately they work it out and their love for each other and the baby grows stronger.
Relief. If they've been through a lot together, the kiss could be a sign of relief that they are still there for each other. It could be like a weight lifted off their shoulders, knowing that their connection is strong enough for such an intimate gesture.
It could also be a kiss in the heat of an argument. They've been bickering, but suddenly realize their underlying feelings for each other, and the kiss is a way to end the fight and start a new chapter in their relationship.
Obviously, Cyd and Naldo would be the main characters. They are the ones having the baby, so the story would revolve around them. Their reactions, emotions, and actions would be central to the plot.
Their families would play a big role too. Rachel's dads would be very involved, using their wisdom to help Rachel and Finn make important decisions about the baby's upbringing. Finn's mom would also be there, providing maternal advice and helping with babysitting. Even some of the teachers from the school might support them, like Mr. Schuester giving them some flexibility in their schedules to take care of the baby.
The priesthood of an ancient Egyptian cult that has been forgotten but still has some lingering power could be antagonists. They believe that the union of Sadie and Anubis is against the old ways and will bring bad luck or some sort of cataclysm. They might use dark magic to try and separate Sadie and Anubis. Also, there could be a jealous god or goddess, perhaps Isis, who is used to being in a position of power and influence. She might see Sadie as a threat to her status, especially if Sadie's relationship with Anubis gives her some sort of special powers or influence in the divine realm.
It could be that the baby is an alien baby who crash - lands on a planet where the beast is the dominant species. The beast might be a huge, furry mammal - like creature.
The main characters would obviously be the five Avengers. It could be Iron Man, Captain America, Thor, Black Widow, and Hulk. And of course, the baby would be a central character as well. Maybe the story could focus on how each of the Avengers interacts with the baby differently. For example, Iron Man might use his technology to create baby - friendly gadgets, while Thor might tell the baby stories of Asgard.
Amy is also a significant character. She is strong - willed and has a deep affection for Sonic. In this fanfiction, they are the parents of the baby, so they play crucial roles in the story's development.
Their manager or agent could also be part of the support system. They could help Alvin and Brittany adjust their work schedules so that they can have enough time to take care of the baby. They might also arrange for some special accommodations, like a nursery backstage during their performances. Additionally, any close friends or neighbors in their fictional world could be there to offer a helping hand, whether it's babysitting for a short while or just providing some words of encouragement during tough times.
