A fanfic writer can effectively portray Ron's jealousy of Harry and Hermione by creating situations that trigger it. For example, if there's a school event where Harry and Hermione are paired together for a task while Ron is left out. His reactions in such situations, like sulking or trying to undermine their success, would show his jealousy. Also, the writer can use internal monologues of Ron, where he admits his jealousy to himself, saying things like 'I know I shouldn't be jealous, but I can't help it when they seem so close without me.'
To effectively portray Ron's jealousy, the writer should delve into Ron's insecurities. Ron has always had a bit of an inferiority complex compared to Harry's fame and Hermione's intelligence. The writer can show how these insecurities are magnified when he sees Harry and Hermione getting closer. For example, Ron might start comparing himself unfavorably to them in his thoughts. He could also isolate himself from them, which would be a clear sign of his jealousy and internal turmoil.
The writer can show Ron's jealousy through his body language. For instance, when he sees Harry and Hermione laughing together, he might clench his fists or look away with a scowl. His dialogue can also be a giveaway. He could make snide remarks like 'Oh, look at the two of you, so perfect together.' This would immediately signal to the readers that he's jealous.
In these fanfictions, Ron's jealousy is portrayed in various ways. Sometimes he'll try to interfere with Harry and Hermione's time together. He might create small misunderstandings between them on purpose. Other times, he'll show his jealousy more subtly, like by looking sad or disappointed when they share a private joke or moment. His body language can also give it away, like crossing his arms and frowning when they are being friendly with each other.
Show his change in behavior. He might stop joking around as much, which is a big part of his character. His appetite could change, either eating too much or too little. Also, his sleep patterns could be affected. For example, he could have nightmares or insomnia.
Show the contrast in the character's dialogue. They might say all the right words of apology, but their tone could be off. Maybe it's a bit too sugary or has a hint of sarcasm in it. This would make it clear that the smile is fake. Also, the writer could describe what the character is thinking during the apology, like 'She apologized with a fake smile, all the while thinking how stupid this was.'
Often, the baby is portrayed as having a combination of Ron and Hermione's traits. Smart like Hermione, with a bit of Ron's sense of humor. For example, in some fanfictions, the baby might be really good at solving puzzles (Hermione's trait) but also tell really cheesy jokes (Ron's trait).
The writer can use descriptive language. For example, describe Aang's facial expressions like 'Aang's eyes, usually full of life and hope, were now dull and filled with sorrow. His lips quivered as he tried to hold back his tears.' Also, show his body language such as slumping shoulders and a slow, heavy gait. Another way is through his actions. He might withdraw from his friends, spending more time alone meditating or just sitting quietly, lost in his thoughts.
They can describe his physical symptoms well. For example, 'Harry's hands trembled uncontrollably as his chest tightened, making it hard to draw a full breath.'
Another way is to contrast his normal, bespectacled self with this new, glaring - without - glasses version. Maybe in the story, his friends are so used to seeing him with glasses that when he glares without them, it has a different impact on them. The writer can use this to create interesting character interactions and development within the fanfiction. For instance, Hermione might be initially shocked but then realize the new level of intensity Harry has reached.
The writer can use body language. For instance, they can describe how Harry's eyes look downcast, his shoulders slump, and he just shakes his head slightly instead of speaking. This non - verbal communication can show that he has chosen not to talk.
Maybe Harry uses his magic skills to immobilize Ron. He could cast a spell like 'Petrificus Totalus' on Ron right when he's about to attack Hermione, thus stopping the beating.
A writer can describe Finn's physical reactions. For example, they can write about his eyes welling up with tears that start to roll down his cheeks. Mentioning how his voice might crack when he tries to speak can also be effective. Another way is to show his body language, like his shoulders slumping as he cries.
