A possible scenario is that Percy and Annabeth stumble upon a riddle or a series of tests in Tartarus. These tests are set up by an ancient and powerful entity. As they solve each part of the riddle or pass each test, they gain a piece of the key to escape Tartarus. Along the way, they have to use their combined skills, Percy's strength and water - based powers, and Annabeth's wisdom and strategic thinking.
One interesting scenario could be Percy and Annabeth finding a hidden, powerful weapon in Tartarus that gives them an edge against the monsters there. Maybe it's a sword that can cut through the very fabric of Tartarus's darkness.
They could discover a lost civilization in Tartarus. This civilization might have a way to manipulate the very fabric of Tartarus itself. Percy and Annabeth would then have to learn the ways of this civilization in order to use it to their advantage. Maybe they have to earn the trust of the civilization's leaders by helping them with their own internal problems first.
Well, one scenario could be that Percy is really careful not to wake her up. He might just sit there and watch her sleep, thinking about how much she means to him. Another could be that when she wakes up, she has a really cute sleepy look and Percy can't help but smile at her.
Perhaps in a fanfiction, they kiss after a long separation. Percy has been away on a mission for a long time, and when he returns, Annabeth can't hold back her feelings anymore. Their kiss is full of longing and relief at being reunited.
One interesting scenario could be Percy and Annabeth getting lost in a magical forest that only appears in fanfiction. They might have to use their combined skills and knowledge to find their way out, facing strange creatures along the way.
One interesting plotline could be their struggle against the various monsters in Tartarus. For example, facing off against the giants or other terrifying creatures that lurk there. Another could be their search for a way out while dealing with the psychological toll of being in such a dark and desolate place.
One more plot idea could be that Percy and Annabeth are somehow affected by the dark magic of Tartarus. It changes them in some way, either physically or mentally. They then have to deal with these changes while still trying to escape. This could lead to some really intense internal and external conflicts as they struggle to stay true to themselves and also find a way out of Tartarus.
In some fanfictions, a possible plot development is that Percy and Annabeth discover a long - lost secret or power within Tartarus. This could be something that gives them an edge in their fight to escape or a knowledge that changes their perspective on the whole Greek mythology world. As they explore Tartarus, they may find ancient artifacts or meet forgotten gods who have been trapped there for ages. These encounters can lead to unexpected alliances and revelations that add depth to the story.
One possible scenario could be that Percy is overpowered by the various monsters in Tartarus. Maybe the sheer number of foes like the giants or the more terrifying creatures there are too much for him to handle, leading to his death.
In some fanfictions, mortals might meet Percy and Annabeth in a coffee shop. Percy could accidentally use his powers to make a small water fountain out of a cup, and Annabeth would quickly cover it up while the mortals are left wondering what just happened.
One interesting scenario could be Percy and Annabeth getting lost in a magical forest that wasn't in the original books. They might have to use their combined skills, Percy's water powers and Annabeth's strategic thinking, to find their way out. Another could be them facing a new monster that is immune to their usual attacks, forcing them to be creative in their defense. And they could also have a moment where they share a really deep conversation about their future together, away from all the chaos of their quests.
