One common plot device is the 'what - if' scenario. For example, what if Hermione had been the one to save Harry from the Dementors instead of his father's Patronus? This can lead to a deeper emotional connection between them. Another is the 'arranged - relationship' plot, where they are forced to pretend to be in a relationship for some magical reason, but end up falling in love for real. Also, the 'jealousy' plot device, where they get jealous of each other's relationships with other characters and realize their true feelings.
A typical plot device could be the influence of an outside force. Say, a kind wizard or witch comes to the Dursleys and makes them understand the importance of Harry and his magic, and then they start to love him. Also, it could be that Harry himself shows extraordinary kindness towards the Dursleys in a difficult situation, which melts their cold hearts and changes their attitude towards him.
One common plot device is the redemption arc. Narcissa may be portrayed as turning away from the dark side, and Harry, seeing this change, is drawn to her. Another is the protection plot, like Narcissa protecting Harry for some reason, which then leads to a bond between them. And sometimes, there's a magical bond or curse that forces them to interact and eventually fall in love.
One common plot device is the use of mind control or dark magic spells on Hermione. This forces her into the slave role. Another is the idea of Bellatrix using Hermione to get to Harry or the other members of the Order. Sometimes, there's a focus on Hermione's inner strength as she tries to break free from the slavery, which is also a plot device to create tension and drama.
A frequently used plot device is the protection of the timeline. Hermione, as a Time Lady, has to safeguard the integrity of the wizarding world's timeline from those who would try to change it for their own gain. Also, the idea of alternate timelines can be explored. For example, what if Voldemort won in a different timeline? Hermione might have to travel there and fix things. There could also be plot devices related to her newfound powers clashing with the existing magical order in the wizarding world.
One plot device might be a double - agent situation. Hermione could be mistaken for a double - agent because of her different abilities and background, and Bond has to figure out the truth. This adds an element of mystery and suspicion to the story.
A plot device could be Cedric getting involved in Harry's personal quests. For instance, if Harry is trying to figure out something about his parents, Cedric may insert himself into the situation, believing he can protect Harry better that way. He might also try to monopolize Harry's time for training or studying, which could lead to some tension between them as Harry might feel smothered.
A plot device often used is the 'redemption arc' for Rodolphus. Maybe he starts to question his Death Eater ways because of Hermione. He could show some kindness or vulnerability that Hermione is attracted to. Also, the 'fish out of water' situation can be used. For instance, if Rodolphus is forced to work with Hermione in a non - Death Eater context, like in a magical research project, and their relationship blossoms from there.
One common plot device is the use of a love potion or a spell gone wrong that initially brings Hermione and a Malfoy together. Another is the discovery of a long - lost prophecy that dictates their union for the greater good of the wizarding world.
Well, a typical plot device is the danger that drives Harry to the Malfoys' in the first place. It could be that he's being chased by Death Eaters or some other dark force. Then, there's the element of family opposition. Their families have been enemies, so the relationship is forbidden in a sense, which adds to the drama. And often, there's the character growth aspect. Both Harry and the Malfoy character grow as individuals while falling in love, like Harry learning to see beyond the Malfoy family's bad reputation and the Malfoy learning about true friendship and love from Harry.
Often, Hermione's injury serves as a catalyst for character development. Her own strength and intelligence are put to the test as she has to deal with being injured. She might have to rely on her knowledge of magic in new ways while being incapacitated. And there could be a sub - plot about her relationship with other characters. Maybe she and Ron grow closer as he takes care of her, or she and Harry have deeper conversations about the risks they all face. This all makes for an engaging story.
