I'm guessing that:


 * More information on Martin's background is given


 * More information on Ice King's background is given


 * More information on Marceline's background is given


 * More information on PB's background is given


 * Jake's background may be further examined


 * Finn's background may be further examined


 * Flame Princess's background may be further examined


 * The Mushroom War may be further examined


 * I'm guessing that the season finale will have something to do with the Lich, the Psychic Tandem War Elephant, Betty, Martin, or Joshua/Margaret.
