Maybe Remus leaves because he feels unworthy. He has always seen himself as a danger and an outcast. Despite Tonks's love, he can't shake off his self - loathing. So, in the fanfiction, he leaves while Tonks is pregnant, leaving her heartbroken. However, their friends, like the members of the Order of the Phoenix, might try to convince Remus to come back and be a family with Tonks.
Tonks would likely be extremely heartbroken. She loves Remus deeply and having him leave while she's pregnant would be a huge shock. She might first go through a period of denial, not believing that he's really gone. Then she would probably be angry, feeling betrayed by the man she loves.
One possible scenario in this fanfiction could be that Teddy shows some unique magical abilities that remind Remus and Tonks of their own magical heritages. Maybe Teddy can transform in a way that combines both werewolf and metamorphmagus traits, which would be a really interesting plot point. It could also explore how Remus and Tonks, who had such a tragic end in the original story, get to experience some happy moments with their son Teddy through the magic of fanfiction.
One idea could be to focus on how they prepare for the baby's arrival. Maybe Remus is worried about his werewolf condition affecting the child, and Tonks has to constantly reassure him. They could start decorating the nursery with magical elements.
Love against all odds is a very common theme. Given Remus' condition as a werewolf, they face a lot of opposition and prejudice. Fanfictions often explore how their love overcomes these difficulties.
Maybe it's because Hermione represents a new beginning for Lupin. She has a different energy compared to Tonks. Lupin could be drawn to Hermione's thirst for knowledge and her ability to look at things from a unique perspective. In fanfiction, the author can create all sorts of reasons, and this could be one of them.
There's also 'Love in the Shadows'. This fanfic focuses on the more secretive aspects of their relationship. It portrays how they communicate in the midst of Voldemort's rising power, with Tonks using her skills as an Auror to protect Remus, and their love growing stronger through shared hardships.
Fanfiction.net is a great place to start. It has a large collection of fanfictions about various characters, including Remus and Tonks. You can search by the characters' names or by tags related to their relationship or the Harry Potter universe in general.
Well, it could be about Teddy having a dream where he meets his parents. In the dream, Remus and Tonks are as he's always imagined them. They tell him how proud they are of him, even though they didn't get to see him grow up. This simple encounter could be a very moving and emotional one, with Teddy waking up with a newfound sense of purpose and connection to his parents.
Well, at first, it might be a bit of a shock for both of them and put some strain on their relationship. But as they come to terms with the pregnancy, their bond would strengthen. Remus would start to see himself in a new light, as a father - to - be. Tonks would be excited about the new life they are bringing into the world. They would have to work together more closely, sharing household chores, preparing for the baby's arrival. Their relationship would evolve from a somewhat uncertain love affair to a more stable, family - oriented partnership.
