Perhaps in the fanfic, the weight difference is symbolic. Oliver Wood's greater weight could represent his groundedness, his connection to the more physical aspects of the wizarding world like Quidditch. Percy Potter, if he's more into academic or bureaucratic matters in the story, might be presented as lighter in a sense of being less 'tethered' to the physical world. It could be a creative device to show how different their worlds and focuses are within the narrative of the fanfic.
Well, it could be just a random physical characteristic given for comical effect. Maybe the author wanted to create a contrast between Oliver Wood's more solid, perhaps muscular build compared to Percy Potter. It might also be used as a way to emphasize Oliver's presence or strength in a humorous way.
It could start with simple descriptions. For example, when they first meet or are in a group scene, the author might mention how Oliver seems more solidly built compared to Percy. As the story progresses, it might be used in action scenes. If they're in a situation where they have to move something or run, Oliver's greater weight could be shown as an advantage or disadvantage depending on the circumstances.
In Potter fanfic, Oliver Wood is often depicted as a very dedicated Quidditch player. When it comes to 'greater weight' in relation to him, it could refer to the heavy responsibilities he has as the Gryffindor Quidditch captain. Percy, on the other hand, is known for his strict adherence to rules. In fanfics, these three elements can be combined in various ways. For example, a fanfic might explore how Oliver's leadership in Quidditch and the 'greater weight' of his role affects Percy's view of Gryffindor house's reputation, especially since Percy is so concerned with the house's standing in the school.
Perhaps a fanfic where there's a spell gone wrong that makes Oliver Wood gain weight. Percy, with his knowledge of the wizarding rules and regulations, tries to find a way to reverse it. And Potter, well, he could be the one who encourages Wood not to give up. The story could explore how Wood copes with this new physical state, his insecurities, and how his relationship with Percy and Potter changes during this time.
Well, it could be a story that plays with the idea of Oliver Wood being in a position where his weight is a key element in relation to Percy Potter. This could be part of a more complex plot where there are misunderstandings or challenges. For example, if they are in a situation where they have to work together on a task, and Wood's weight causes some sort of disruption or advantage that they have to deal with. It could also be a fanfic that is exploring body - related themes in a magical context, but in a light - hearted way.
Maybe it's because Oliver Wood is more muscular. He's a Quidditch player and all that physical training might have built up his muscle mass more than Percy, who is more into academic and administrative work. So the difference in their body composition could lead to Oliver being much heavier.
I'm not sure specifically which fanfic this refers to. But generally, if in a fanfic Oliver Wood is heavier than Percy, it could be shown through physical descriptions. For example, when they are standing side by side, the author might describe how Oliver's frame is broader and more solid - perhaps he fills out his Quidditch robes more fully compared to Percy. Or when they are participating in some physical activity like climbing stairs, Oliver might be shown to be a bit slower or more out - of - breath due to his extra weight.
One possible reason could be different lifestyles. Oliver, being so focused on Quidditch, might have a diet that consists of more hearty and filling foods to keep his energy up during practices and games. Percy, on the other hand, might be more into lighter, more 'intellectual' meals as he is often buried in books and administrative tasks. This difference in diet could lead to Oliver being heavier.
There could be a theme of self - discovery. Percy Potter might discover something new about himself, like his patience or his ability to handle unexpected and uncomfortable situations, when Oliver Wood's weight pins him. Another theme could be the power of humor. The whole situation is rather absurd, and the fanfic could use this absurdity to show how humor can defuse tense or strange situations, and how it can bring two characters closer together.
In Potter fanfic, Oliver Wood's 'greater weight' could be his leadership role in Quidditch. This might be related to Percy as Percy is someone who respects authority. So, Percy could either support Oliver in his role, like helping with administrative tasks related to the Quidditch team. Or, if Oliver's actions seem to go against Percy's sense of order, there could be conflict.
