By showing Amy's reaction. The writer could describe how Amy's face falls, her eyes well up with tears, and she runs away sobbing. This would indicate to the readers that Sonic has said or done something to hurt her.
She can also get angry. After being hurt, Amy might lash out at Sonic, telling him how his thoughtless actions have affected her. In some fanfictions, she'll try to make Sonic feel guilty by reminding him of all the times she's been there for him. And sometimes, she'll try to change herself in an attempt to get Sonic to notice her in a different way, like trying to be less affectionate or more like Sonic in her adventurous spirit.
One common plot could be Sonic accidentally ignoring Amy's efforts to get closer to him. For example, Amy might plan a special picnic for them, but Sonic is so caught up in his adventures that he forgets about it, leaving Amy heartbroken. Another plot might involve Sonic making a thoughtless comment about Amy's appearance or her overly affectionate nature in front of others, which would deeply wound her pride and feelings.
In the fanfiction, Sonic might say some harsh words to Amy in the heat of an argument. For example, if they are discussing Sonic's constant running around and not spending enough time with her, Sonic could snap and say something like 'You're always so clingy, Amy!' which would deeply wound her feelings. Amy, who loves Sonic dearly, would be devastated by such a statement. The story could then revolve around how they deal with this rift in their relationship, whether they make up or grow further apart.
Amy can be developed by showing her growth from a victim to a survivor. She could start as a meek character but gradually become more assertive. For example, she might start to speak up for herself more often.
It can bring new perspectives to the fandom. Fanfiction allows fans to explore different relationships and scenarios that may not be shown in the official Sonic media. For Sonic and Amy in lemon fanfiction, it can make some fans see their relationship in a more romantic or complex light, which might influence how they view the characters in general. It can also increase the creativity within the fandom as fans share and discuss these fan - created stories.
Amy might initially be in denial. She could think that Sonic didn't really mean to break her heart and that it was all a misunderstanding. So she might try to act normal around him at first.
Amy Rose shows her love by constantly chasing Sonic. She is always by his side during his adventures, ready to help. For example, she'll bring him a meal or offer to patch up his wounds.
One effective way is by using internal monologues. This allows the reader to peek into the character's thoughts and see how they are evolving. For instance, in 'The Bell Jar', Esther Greenwood's internal monologues show her changing mental state. The writer can also use contrast. By showing how the character is different from who they were in the past, like their appearance, habits, or values, the development becomes evident. And, of course, the character's reactions to events are important. A more mature reaction to a difficult situation as the story goes on is a sign of development.
Well, Sonic is a hero at heart. So when Amy gets hurt, he would first assess the situation calmly, but inside he'd be worried. He'd make sure she was stable and then look for the cause of her injury. If it was an enemy, he'd go after them. But he'd also be very gentle with Amy, talking to her softly and reassuring her that she'll be okay. He'd do whatever it takes to see her back on her feet again, like finding special herbs or items that could speed up her healing process.
Tails would probably be very helpful. He'd use his intelligence to make sure Amy has a comfortable pregnancy, like creating special devices for her. Knuckles might be a bit awkward at first but would ultimately be very protective. He'd stand guard to make sure no harm comes to Amy and the unborn baby.
