One interesting fanfiction could be about Finnick and Peeta teaming up during the games in a way that wasn't shown in the original.

In many fanfictions, Katniss also plays an important role when it comes to Finnick and Peeta.

Whether it's her trying to understand their friendship or being caught in the middle of some sort of tension between them.
