There could also be other characters like Tyrion. He might be involved in advising Jon and Daenerys on how to raise the children, or he could be helping to protect the twins from political intrigue within the Seven Kingdoms.
One interesting plot could be the twins growing up in a post - war world. They might inherit the leadership qualities of their parents, Jon and Daenerys. The story could focus on how they are trained to rule and bring peace to the Seven Kingdoms.
One great fanfiction could be where Jon Snow's twin sister plays a crucial role in the politics of Westeros. She might use her wits and charm to gain allies in King's Landing, much like Margaery Tyrell. Another idea could be that she has some hidden powers and uses them to protect Jon and their friends from the White Walkers. There are also fanfictions where she is a key figure in uniting the different houses against a common enemy.
A lot of fanfictions use the 'redemption' trope. Maybe she makes a mistake early on, like trusting the wrong person, and then has to redeem herself. There's also the 'forbidden love' trope. She could fall in love with someone she's not supposed to, like a member of a rival house. This adds a lot of drama to the story. Another popular one is the 'mentor - mentee' trope. She could be mentored by an old and wise character, like Brynden Rivers, and through that mentorship, she grows into a strong and capable leader in the world of Game of Thrones.
I'm not sure specifically who Jon Franklin is without more context. He could be an ordinary person with a passion for sharing true stories, or perhaps a professional storyteller, journalist, or writer.
There could be a wise old wizard who gives Jon advice on how to hatch and take care of the dragon. Maybe there's also a rival of Jon's who is jealous of his discovery and tries to steal the dragon egg.
Was Jon Chen pregnant? Some articles claimed that Chen Qiaoen had announced his pregnancy. His belly was bulging and he was very pregnant. His boyfriend, Alan, had also held a three-year anniversary celebration. However, other articles mentioned that Jon Chen was not pregnant. The previous rumors were because she had gained weight or reposted news about her pregnancy. Jon Chen himself also denied the pregnancy rumors in his post. Therefore, based on the information provided, it was impossible to determine whether Qiao En Chen was pregnant.
He could meet some of the last remaining Valyrian descendants. They might be hiding in the ruins, still holding on to their ancient knowledge and traditions.
It's interesting because it can explore different aspects of their characters. For example, how their relationship might change if they were in different situations, like facing a common enemy or having to make difficult decisions together. It gives a new perspective on their individual personalities as well.
