I don't have any data on the popularity of this specific fanfiction. It could be popular among die - hard 'Being Human' fans who are interested in exploring different and often darker scenarios between the characters.
I'm not sure specifically as I haven't read this particular fanfiction. But generally, in the 'Being Human' universe, if Aidan drinks Josh's blood, it could be about a dark turn in their relationship, perhaps exploring themes of power, addiction, or a breakdown of the normal boundaries between them.
Their relationship can be developed through shared challenges. For example, if they are both framed for a crime they didn't commit within the supernatural community. They would have to rely on each other to clear their names, and in the process, their trust in each other would grow. They might also have heart - to - heart conversations where they open up about their fears regarding their respective natures.
Perhaps there is a mysterious illness spreading among the supernatural community that is affecting both vampires and werewolves. Aidan and Josh team up to find the source of the illness. Along the way, they meet some old enemies who they have to either fight or make peace with in order to get to the bottom of the mystery. As they search for a cure, they also learn more about the true nature of their own species.
In some fanfictions, Edward's drinking of human blood could be a part of a darker, alternate universe. Maybe he's been turned into a more feral vampire and has to relearn how to control himself with the help of other characters.
Fanfiction about 'being human' with Aidan and Henry can be really interesting. It often explores the unique relationship between these characters. Writers might delve into their personalities, their backstories, and how they interact within the world of 'being human'. It could show different scenarios that weren't explored in the original work, like their adventures together or how they deal with challenges specific to their natures.
One thing that makes it unique is the combination of two very different supernatural beings. Aidan, a vampire, and Henry, a werewolf, bring their own sets of rules and characteristics to the story. This creates a rich tapestry for the fanfiction writer to work with. Another aspect is the potential for exploring the gray areas between good and evil that these characters inhabit.
Aidan is a vampire. He has to deal with his blood - thirsty nature while also trying to fit into the human world. He has a long history and many secrets which are often explored in the fanfiction.
One common theme is friendship. Aidan and Sally are often depicted as having a very strong friendship that endures through many difficulties. Another theme is self - discovery. They both are supernatural beings and in the fanfictions, they often go through processes of understanding themselves better. For example, Sally learning about her powers and limitations.
Well, I haven't come across such a fanfiction myself. But you could also check out some 'Being Human' fan forums. There, fans might discuss or even recommend fanfictions about Aidan and Sally's possible pregnancy. They might share their own ideas about how such a plot could develop in the fanfiction world. It could be really interesting to see different perspectives from the fans.
