In the fanfic, it's possible that Jon Snow uses his warging ability. He might warg into a large and fearsome animal, like a direwolf or even a wild boar. He could then send this animal into the middle of the Red Wedding chaos, causing enough distraction for him to step in and stop the massacre. He could also use his connection with the Northmen present, appealing to their loyalty to House Stark and the North, convincing them to turn against the Freys and Boltons.
In this fanfic, House Bolton would also suffer. Their alliance with House Frey was a key part of their plan to gain more power in the North. If Jon Snow stops the Red Wedding, their scheme fails. They would lose the support of many of their allies who were only in it for the chance to get on the winning side. For House Tully, they would be grateful to Jon Snow. Their family members were also at risk at the Red Wedding, and if Jon Snow saves them, it would strengthen the bond between House Tully and House Stark, potentially leading to future alliances and mutual support in the power struggles of Westeros.
Another possibility is that Loki teams up with other characters. He could form an alliance with the Avengers or some other powerful beings in the universe. Together, they could come up with a plan to stop Thanos. Loki could contribute his unique skills, like his ability to shapeshift and infiltrate Thanos' ranks, and then they could launch a coordinated attack.
Naruto could also use his new jutsu or skills he has acquired. He might show Sasuke that he has become stronger and that they could face whatever Sasuke is running from together. He could block Sasuke's path physically and then start talking some sense into him, like how leaving won't solve his problems but will only create more.
She could use her Faceless Men skills. Maybe she disguises herself as one of the serving staff. Since she has been trained to blend in and move unnoticed. She could then poison the wine or food that was meant for the main players in the Red Wedding. This way, she can stop the massacre before it even starts.
In fanfiction, Harry Potter might stop the Red Wedding by using magic to create a diversion. For example, he could conjure up a horde of magical creatures that would disrupt the event and give the intended victims a chance to escape.

Well, the dragon would obviously be a main character in its own right. It could have its own personality and motives.
Often, their relationship begins with a bit of tension. Daenerys is a strong - willed queen, and Jon is a respected leader in his own right. But as they get to know each other better, they start to see the good in one another. Their relationship could develop through conversations around a campfire, where they share their dreams and fears. And as they become more intimate, they start to rely on each other more, both emotionally and in the political games of Westeros.
In this fan fiction, their relationship may develop in a complex way. Stannis may initially use Jon as a tool to gain more support in the North, seeing his Stark name as an advantage. But as Jon shows his true self and his unique skills, Stannis starts to value him for who he is. Jon, on the other hand, may be initially hesitant about serving Stannis but gradually realizes that he can learn a great deal from him. Their relationship could be full of power struggles, but also moments of mutual admiration and growth.
In this fanfiction, Jon Snow's character could develop in several ways. Firstly, his relationships with other characters might change. He may form stronger bonds with his fellow soldiers, learning to trust them more. Secondly, his understanding of politics and power could grow. As he is involved in Robb's war, he witnesses the political maneuverings that go on behind the scenes. This could make him more cynical or more determined to fight for justice, depending on how he interprets these events. Moreover, his combat skills are likely to improve, and this newfound strength could give him a different perspective on his own capabilities and his place in the world.
