The plot could center around Kenna's pregnancy journey. She would have to deal with the physical and emotional changes while being in the court environment. Bash would be her pillar of support. For example, he could stand up to those who try to undermine her during this vulnerable time.
One possible fanfiction could involve Bash finding out about Kenna's pregnancy. He might be initially shocked but then filled with joy. They could face challenges from the court, as their relationship was complex in the 'Reign' series. Maybe they have to fight for their future together and the future of their unborn child.
I have no information on Kenna James' real wife, so I can't determine if there are interesting facts in their stories. But if Kenna James is involved in a creative field, perhaps his wife has been a source of inspiration for him, which could be an interesting aspect of their relationship story.
Searching for Kenna and Bash pregnant fanfiction can be a bit of a hunt. Some fanfictions might focus on the emotional journey of Kenna during the pregnancy, how Bash reacts, and how it affects their relationship with other characters in the story. You may need to dig through different tags and categories on fanfiction platforms to find the ones that really catch your eye.
Archive of Our Own (AO3) is a great place to start. It has a large collection of fanfiction from various fandoms, and you can search for Kenna and Bash stories with the pregnancy tag.

In my opinion, 'Reign on Me' isn't a true story. It likely combines imaginative elements to craft an engaging narrative rather than being a direct account of real-life events. Maybe there are some common themes or emotions that can be related to real life, but not the entire story.
