Maybe it was someone from Elsa's past that we don't know much about yet. For example, a childhood friend who she had lost touch with but who returned to her life. They rekindled their friendship which then turned into a deeper relationship, resulting in her pregnancy.
The plot could also involve the father of the baby being a mysterious figure. Maybe he's from a far - off land that Elsa visited during her adventures after the events of the Frozen movies. And as she gives birth, the baby could inherit some of her ice powers, which would lead to a whole new set of challenges and adventures for Elsa as a mother, like teaching the baby to control its powers from a very young age.
Perhaps it could be Kristoff. Although he was more interested in Anna in the original story, in fanfiction, the relationships can be reimagined. They could have developed a closer bond over time and he could be the father.
It could be some other wizard who Harry had an unexpected encounter with. Maybe it was a wizard who was secretly in love with Harry and used some sort of love - related magic that had an unforeseen consequence.
It could be that the father is an unknown wizard who Harry had a brief encounter with. Maybe it was a one - time magical connection that led to the pregnancy.
Well, it could be Finn. They had a long - standing relationship on the show, and it would be a natural choice for him to be the father in the fanfiction. They had a deep connection, and if the story is set in a timeline where their relationship continued to develop, it makes sense that he would be the one.
Another possibility is that the father could be a completely new character introduced in the fanfiction. This new character could be from a far - off land and bring some new elements to the story, like different ninja techniques or a new perspective on the ninja world that influences the upbringing of the baby.
It could be a mortal man who somehow managed to catch Artemis's eye. Maybe he was a great hunter like her, and their brief encounter led to the pregnancy.
Puck could be a likely candidate as he had a relationship with Quinn in the Glee series. Their on - again - off - again relationship makes it a plausible scenario for him to be the father in the fanfiction.
It could be one of her long - time friends in the Lost Girl world. Maybe someone she has a deep, unspoken connection with. This person might be revealed to be the father as the fanfiction progresses and there could be a whole backstory about their relationship that led to this pregnancy.
She might face the challenge of controlling her powers during labor. Since her emotions are closely tied to her ice powers, the pain and stress of giving birth could cause unexpected ice surges. Also, she has to deal with the public perception. As a queen, her giving birth is a big event for the kingdom, and there could be a lot of pressure on her.
