A more complex plot could be that there is a traitor among the Tomorrow People and Stephen and John suspect each other at first. As they investigate, they start to uncover secrets about each other and the community. In the end, they find the real traitor and strengthen their relationship through this ordeal. This would involve a lot of mystery, suspicion, and character development.
Another possibility is that it's a story of rivalry. Perhaps they both have different ideas on how to lead the Tomorrow People or deal with the outside world. This could lead to conflicts between them, but in the end, they realize they need to work together for the greater good.
One common theme is the exploration of John Roger's powers. Writers often delve into how he discovers new abilities or how he copes with the challenges that come with his powers in the context of The Tomorrow People world.
You can try fan fiction websites like Archive of Our Own (AO3). It has a large collection of fan fictions from various fandoms, including The Tomorrow People. Just search for 'John Roger' and 'Tomorrow People' in the search bar, and you'll likely find some interesting stories.
Another common theme is adventure. Fanfics such as 'Stephen and Hosuh's Great Adventure' often have them going on exciting quests together. This not only tests their friendship but also shows their individual growth during the adventure.
One common theme is the exploration of moral ambiguity. Sherlock is often seen as a 'good' character, Moriarty as 'evil', and John as the moral compass. Fanfics play with these roles, blurring the lines. For example, in some, Moriarty may have a redeeming quality. Another theme is the intense emotional and psychological relationships. There's often a love - hate dynamic between Sherlock and Moriarty, and John is the stabilizer in this volatile mix.

One of the themes that often pops up is growth. Both John and Vriska can grow as characters through their interactions in the fanfics.

Another good one is 'John Laurens: My Heart's Desire'. This fanfic focuses a lot on the emotional side of the relationship. It shows how the reader and John Laurens support each other through the hardships of the revolutionary era. The descriptions of the settings also add to the overall charm of the story.
