Another theme could be regret. Snape has done many things he may not be proud of, and in fanfiction, when he reflects on those actions, it can lead to tears. For example, his treatment of Harry at times.
One common theme is regret. Snape often cries due to the many regrets in his life, like his role in Lily's death. Another theme is loneliness. Fanfictions often depict him crying because he feels so alone in his world, with his secrets and his unrequited love.
Another theme is loneliness. When Harry feels alone in his struggles against Voldemort or in dealing with the wizarding world's expectations, he often cries. In some fanfictions, he's isolated in Hogwarts during holidays and this leads to his emotional outbursts.
One common theme is guilt. Draco has done a lot of not - so - nice things during his time at Hogwarts, and in these fanfictions, he often feels guilty about it which leads to his crying. For example, his actions towards Harry and his friends.
Guilt is a very common theme. Edward often blames himself for various things like the harm he has caused to his friends or the chaos in the world due to his alchemy. So, in fanfictions, this guilt can lead to his crying.
In some fanfictions, Snape might awkwardly try to comfort Harry. Given his own complex personality, it wouldn't be an easy or natural gesture for him. He might pat Harry's shoulder stiffly or offer some gruff words of reassurance like 'Pull yourself together, Potter.'
Love is also a theme. It could be his unrequited love for Lily Potter. In redo fanfiction, sometimes this love is explored in a different way, like he gets a chance to express it more openly or change things related to it. He might also form new relationships that were not possible in the original story.
Common themes include the power of love and loyalty. In some fanfictions, Snape's love for Lily extends to his relationship with Potter in unexpected ways. Another theme is the struggle between good and evil within their own characters. Potter has his own inner demons to face, and Snape is often seen as a morally grey character. And there's the theme of family, as Potter is an orphan and Snape has his own complicated family history, which can be explored in relation to their relationship.
One common theme is mistrust. Given their personalities in the original Harry Potter series, it's natural for fanfiction to explore how they initially don't trust each other. For example, Snape's double - agent status and Moody's cautious nature can lead to a lot of suspicion between them.
One common theme is Snape's relationship with the Marauders. Fanfictions often explore the animosity and the complex dynamics between them. Another theme is Snape's unrequited love, which is a central aspect in many stories.
In deaged Snape fanfiction, the theme of redemption can be quite prominent. It gives Snape a chance to rewrite some of his past actions or at least be seen in a new light. There's also the theme of identity crisis. He's not the same old Snape, and he has to figure out where he fits now. Additionally, the theme of adaptation is common. He has to adapt to his new physical state, new social situations, and new magical abilities or limitations that come with being deaged.
