who is the father of sarah platt's baby

Marc Platt is likely the creator or author of the 'Marc Platt Christmas Story'.

It could vary depending on the specific fanfiction. Maybe it's a character introduced especially for that story.

Another option could be an alien from Starfire's home planet. This would add an interesting dynamic as the baby would have a strong connection to Starfire's alien heritage. It could also bring in some unique storylines about the alien culture and how it affects the baby's upbringing. Maybe the alien father has certain powers or responsibilities that are passed down to the baby.

I'm not sure exactly who Sarah is without more information from the story. But she is likely a person who has a weight problem and is the focus of the '600 pound life' story.

Sarah is the main character in the story who experiences the tragic events.

It could be someone Ginny had a past relationship with before Harry. Maybe an old schoolmate or a character from a side plot in the fanfiction.

Maybe it's a completely new character, someone from a different part of the wizarding world. He could be a mysterious wizard with a special talent or power that Rose was drawn to. This would open up a whole new set of plotlines as the reader discovers more about this unknown character and his connection to Rose.

It could be Sai. Since they work together and have developed a relationship over time, it's possible that they could end up having a child together.

Another possibility is Clark Kent himself. Their friendship was very strong, and there were always some unspoken feelings between them. A situation where Clark is the father would bring about a lot of emotional turmoil as they both try to figure out how to handle this unexpected development.

The father of Vivian's baby in American Horror Story 1 is Ben Harmon. This is a significant plot point that adds to the drama and complexity of the story.
