Using dialogue with other characters. For instance, if he has a conversation with Nico and he just breaks down while talking, saying things like 'I can't do this anymore' or 'I'm so tired of trying to be strong'. The interaction with another character can highlight the emotional intensity of his breakdown and how it affects those around him.
The author can use physical cues. For example, Kuroko might clench his fists tightly, a rare display of emotion from him. His normally calm blue eyes could narrow and become more intense. Another way is through his dialogue. He could speak in a sharper tone than usual, with shorter, more forceful sentences.
The author can use vivid descriptions of his facial expressions. For example, 'Harry's face turned red, his eyes blazing with fury as he clenched his fists.' This gives the readers a clear visual of his anger.
One way is through detailed descriptions of how she experiences the world without relying on sound. For example, she might be more attuned to vibrations or visual cues. The author could describe how she reads lips with great intensity and how she uses magic in unique ways to compensate for her lack of hearing, like a spell that alerts her to approaching people through a visual signal.
The author can show it through Bella's internal monologue. For example, she could be constantly worried about forgetting to take her meds or how they make her feel different.
The author can use strong dialogue. For instance, having Tony shout out angry words with a lot of force and passion. Words like 'I've had enough!' or 'You'll pay for this!' can quickly convey his anger. Also, the use of expletives (if appropriate for the rating of the fanfiction) can enhance the sense of his fury.
To portray love, an author can show characters' small acts of kindness and consideration. For example, a character making a special meal for their beloved. For obsession, the author can describe repetitive thoughts or stalking - like behavior. In 'Twilight', Edward's over - protectiveness of Bella can be seen as a form of obsession at times.
An author can use vivid descriptions. For example, describe the setting in great detail during this 'last opportunity' moment, like the weather or the place. This can set the mood. Also, slow down the pacing of the narrative.
Well, the author can use flashbacks effectively. Maybe show happy memories of James and then contrast them with his current state of depression. This will highlight how much he has changed. His speech can also be a tool. Slow, monotone speech, or long pauses before answering can show his mental state. Additionally, his attitude towards magic could change. He might lose his enthusiasm for it, which was once a big part of his life. For example, not being excited about new spells or magical creatures anymore.
One way is through his inner thoughts. For example, the author could write about Percy constantly doubting himself, like thinking he's not a good enough hero. His thoughts could be filled with self - blame for the things that went wrong in his adventures, even if they weren't really his fault. Another aspect could be his withdrawal from his friends. He might start avoiding them, not answering their calls or messages, and when he is with them, he seems distant, lost in his own world of despair.
To effectively portray Nightwing's heartbreak, the author can make use of flashbacks. Show the happy times he had before the heartbreak, which will contrast sharply with his current state. The author can also have him make self - deprecating remarks. For instance, 'I'm such a fool for believing in love.' Additionally, his interactions with the environment can be a sign of his heartbreak. He might avoid going to places that remind him of the person or event that caused his pain.
