If we went with the mentor plot it would be Eric realizing how much he cares for Emily when he is preparing her for the games and then when she is in the games he would be trying to get her sponsors to get her things that she needed to survive the games, After that perhaps the focus would be similar to what happened in the books, the love story that fuels a rebellion so an alternate universe version of the Hunger Games story.
Another AU option could be to RP the 74th Hunger Games but instead of Katniss and Peta winning it would be Emily and Eric.
