Well, a great plot for their fanfiction could be centered around a secret alliance within the Games that they form with other tributes.

Perhaps there was a love triangle with another tribute from District 2, which added tension to their bond. And also, a plot could revolve around Cato and Clove finding a way to change the rules of the Games from within the arena.
One idea could be a pre - Hunger Games story where Cato and Clove train together and form a deeper bond than just allies. Maybe they share their fears and dreams away from the prying eyes of the other tributes.

One idea could be that Cato and Clove are in a high school version of the Hunger Games training program.

And a third idea is that they both survive the Hunger Games and have to deal with the aftermath together, facing the Capitol's wrath and trying to start a rebellion from within.
In fanfiction, Clove and Cato could have a backstory that wasn't fully explored in the original Hunger Games.

Their relationship could have been one of friendly rivalry that then turns into a deeper bond during the Games. Cato might be protective of Clove, seeing her as a valuable ally and also someone he cares about on a more personal level. Clove, on the other hand, could be the one who strategizes their moves, using her wits to keep them alive.
In many fanfictions, Cato and Clove are often depicted as having a complex relationship. They are both from the same district, which gives them a certain bond.
