There's not enough information given to know exactly who Mr James is. He could be the author of the story, in which case he might be a writer known for his spooky tales. Or he could be a character within the story, perhaps the protagonist who experiences the Christmas - themed ghostly encounters.
A fanfiction on this topic might also explore the challenges they faced. There could be opposition from some in their respective communities. However, they overcame these difficulties. Pocahontas and John Rolfe's love for each other and their unborn child could be the driving force. Their story could be a tale of love, courage, and the blending of two different worlds through the new life that was about to come into existence.
One common theme is friendship. Often, James and Mr Evans start off as strangers and gradually form a strong bond of friendship. For example, they might help each other through difficult times or share common interests.
A possible plot is that their pregnancy becomes a symbol of unity. People from both their cultures start to see the potential of a new future together. The fanfiction could show how they deal with the physical and emotional changes during pregnancy. Pocahontas might have to adjust to the more European ways of prenatal care that John Rolfe is familiar with, while John Rolfe would learn about the Native American spiritual connection to pregnancy. It could be a story of two people from different worlds coming together to welcome a new life and a new future for their combined cultures.
Another great Mr James story is 'Casting the Runes'. It has an interesting premise where a man is cursed through some strange runic symbols. The sense of impending doom as the victim realizes he's been hexed and tries to fight against it is very engaging. The story also delves into themes of power and the occult in a very effective way.
