One common theme is adaptability. Jack Frost has to learn to adapt to his blindness, like finding new ways to use his powers. For example, he might use the sound of his ice forming to sense his surroundings better.
Overcoming challenges is also a big theme. Jack Frost is often portrayed as facing various obstacles because of his blindness, but he always manages to find a way to rise above them. Whether it's fighting off bad guys or just getting around in his world, he shows great resilience.
Belonging is another important theme. Jack, who is often seen as an outcast in the spirit world, finds a sense of belonging with Jamie. And for Jamie, he feels like he belongs to a more magical and special world when he is with Jack. This mutual feeling of belonging strengthens their relationship and is a key aspect in many of the fanfictions about them.
One common theme is the struggle between different natures. Jack Frost, with his cold and somewhat pure nature, has to deal with the dark and often violent nature of vampires. For example, in many fanfics, he has to fight against the urge to give in to the vampire's bloodlust.
One common theme is the exploration of their powers. Since both have powers related to ice and snow, fanfictions often delve into how their powers can combine or contrast. Another theme is friendship or romance. Many writers like to imagine them as friends or lovers.
Friendship is also a big theme. Jack often forms new friendships in crossover fanfiction. When he meets characters from other universes, they learn to work together and understand each other. This theme helps to bring different worlds together in a positive way.
Another theme is isolation. As a vampire, Jack Frost is often set apart from other beings. He may be shunned by his former friends or the beings of the winter realm. This isolation can lead to self - discovery and him finding new allies or a new purpose in his 'undead' life. For example, in some fanfictions, he befriends other outcasts in the supernatural world.

Common themes include discovery. They are both learning about themselves and each other. Jack Frost might be discovering the softer side of himself through his interactions with Toothiana, who represents kindness. And for Toothiana, she could be exploring a more carefree side with Jack. Another theme is unity. Given their different but complementary powers, they might work together to bring balance to the magical world, which is a theme that shows up in many of the fanfictions.
Another theme is his isolation. As he delves into his dark side, he may push away those who care about him. This isolation can be both a cause and an effect of his darkening. He might feel that no one understands him and his internal struggles, so he further isolates himself, which only makes his dark side stronger.
