Some writers develop their relationship through shared adventures. They go on quests together, face dangerous magical creatures, and in the process, they grow closer. As they protect each other from harm, their bond deepens. Writers might also include some jealousy plots, like when one of them seems interested in another character and the other gets jealous, which reveals their true feelings.
Another storyline might be a time - travel one. They accidentally travel back in time and have to blend in with the past while also trying not to change history too much. During this, their feelings for each other start to change from just sibling - like to something more romantic.
One way is by having them get involved in a magical accident that gives them a unique connection. Maybe they can read each other's minds for a short period. This would force them to be more open and honest with each other, which in turn would develop their relationship. Also, if they were to work on a magic project together, like creating a new spell or potion. During the process, they would learn about each other's strengths and weaknesses and grow closer.
A great plot could be that Alex discovers a long - lost spell book that contains spells that are considered forbidden in the wizard world. As she starts to explore the spells, she attracts the attention of an old and powerful wizard who wants to get his hands on the book. Alex then has to protect the book and herself while also deciding if she should use the powerful and dangerous spells.
One idea could be that Justin and Max are forced to team up for a wizard competition that they initially don't want to do. As they train together, they start to understand each other better and form a closer bond. Another could be that they accidentally swap powers and have to figure out how to live with each other's abilities while also not getting caught by their family. Maybe they get stuck in a magical realm together and have to rely on each other to find their way back home, which would be a great adventure and also a chance for their relationship to grow.
The plot is crucial. A 'best' fanfic might have an engaging and unique storyline that still fits within the world of Wizards of Waverly Place. It could be a new adventure that Justin and Alex go on together, or a situation where they have to overcome a big challenge. Maybe it's a time - travel plot or a story about them dealing with a powerful magical creature. The plot should keep you hooked from start to finish.
You can start by looking on fanfiction platforms like FanFiction.net or Archive of Our Own. These sites have a large collection of fanfics related to various shows, including Wizards of Waverly Place. Just search for 'Justin Alex Wizards of Waverly Place' and you'll likely find some great ones.
Justin could be involved. He might be the one who either tries to help Alex get out of the forced lemon situation or, on the contrary, he could be the one who thinks she should just follow the rules. Another character could be Harper. She might be there to provide some comic relief while Alex is dealing with the lemon thing. For example, she could make jokes about Alex smelling like lemons all the time.
A magical detective who is investigating some strange magical occurrences in the neighborhood that Alex gets involved in. This character could be really serious and by - the - book, which would contrast with Alex's more carefree nature.
A fanfic could focus on a gay wizard who discovers a new form of magic that is only accessible to those who embrace their true selves. He then has to convince the other wizards in Waverly Place that this new magic can be a great addition to their world, all while dealing with some who are prejudiced against his sexual orientation.
I also liked when the Russo family had to compete in the wizard family competition. The different challenges they faced and the unique spells they used were really exciting. It showed how creative they could be with their magic.
