Through character's internal monologues. For example, if writing about Draco Malfoy having mixed feelings about his family's ideology. He could be thinking in his head about how he was brought up to believe in pure - blood superiority, but then he sees the good in some non - pure - blood wizards. This internal thought process shows his mixed feelings clearly.
By showing the contrast in a character's reactions to different situations. For instance, in a fanfic about Ginny, she might be very confident and bold when she's on the Quidditch pitch, but when it comes to her relationship with Harry, she has moments of shyness and self - doubt. This contrast effectively portrays her mixed feelings in different aspects of her life.
Using body language and actions. Let's say a character like Neville. He might show his mixed feelings about going into a dangerous situation. His hands could be shaking a bit (showing fear), but his jaw is set in determination. This combination of physical signs can convey his mixed emotions to the readers.
Using the plot structure is crucial. If the fanfic's plot is about a mystery, like a new dark magic item that's causing trouble in the wizarding world, the 'direction of change' can be shown as the characters get closer to solving the mystery. They change from being confused to having a clear understanding, and this shift is the 'direction of change'.
One interesting 'mixed feelings' theme could be the relationship between Snape and Harry. In fanfic, it can explore the complex emotions of Harry towards Snape. Harry has reasons to dislike Snape because of his treatment in class, but at the same time, he discovers Snape's loyalty to his mother. This creates a mix of resentment and begrudging respect.
Goblins can be shown as highly intelligent and skilled in craftsmanship. For example, in a fanfic, they could be the ones creating the most complex and powerful magical items, like the Elder Wand. Their pride in their work could be a big part of their character.
One way is through dialogue. Harry could passionately explain his reasons to Dumbledore, showing his growth and understanding. For instance, 'Dumbledore, I can't let you do this. We have another way.'
Using body language. For example, a character might unconsciously bite their lip when looking at the other, or their eyes might linger a bit too long. In a Harry Potter fanfic, if it's about Harry and Cho, Cho could blush and look away quickly when Harry gets too close.
In some Harry Potter fanfics, seduction might be portrayed through the use of magic. For example, a character could use a charm to make themselves more alluring. However, it's important to note that this often goes against the more innocent nature of the original series. Fanfic authors sometimes take creative liberties, but it can be a controversial topic among fans.
In fanfic, the Nundu is often portrayed as a huge, hulking beast with a menacing presence. It's shown as very powerful and its poisonous breath is usually emphasized.
In Harry Potter fanfic, elves are often portrayed in diverse ways. Some fanfics might expand on the house - elves like Dobby and Winky. They could be given more complex personalities, for example, an elf who is not only subservient but also has dreams of freedom and education. Some might show elves with magical abilities beyond what was shown in the original books, like the ability to transform into other creatures momentarily to escape danger.
It's often portrayed as a very alluring potion. In many fanfics, the description of its smell is really detailed. For instance, one character might smell freshly baked cookies (if they have a thing for food or a baker they like) and a particular type of flower that grows in a place special to them.
In some Harry Potter fanfic, incendio is portrayed as a very powerful spell. It can quickly create large and intense fires that are hard to control. For example, a character might struggle to contain the fire they've created with incendio.
