Percy Jackson
Annabeth Chase: Throughout the  series, it is shown that they have feelings for each other ; in each book there are hints of romantic tension and flirting. Percy and Annabeth first meet in The Lightning Thief when Percy wakes up after passing out to see Annabeth, whom he described as "pretty", spoon-feeding him nectar and ambrosia, the food of the gods. Percy is confused and irritated by Annabeth's behavior in the beginning of The Lightning Thief, but they develop a solid friendship at the end of the novel from all they had experienced together. In The Battle of the Labyrinth, Percy and Annabeth were supposed to meet up after school for lunch and a movie which Percy's mother, Sally, referred to as a "date" and teased him about it. It is revealed in The Sea of Monsters that Percy carried a picture of Annabeth in his binder and that Annabeth had been tailing Percy with her cap of invisibility on. In The Titan's Curse, Percy meets Aphrodite (Percy momentarily thought she resembled Annabeth), who tells him that he will have a tragic love life; incidentally, Percy meets Rachel a little while after. At the end of the book, he nearly has a heart attack, thinking Annabeth was about to join the Hunters of Artemis. Annabeth kisses him four times, once after winning the chariot race in The Sea of Monsters, though that was only on the cheek, again as she leaves him to fight the telekhines at Mount St. Helens in The Battle of the Labyrinth, in the dining area of Camp Half-Blood, prior to all the other campers throwing them in the canoe lake in The Last Olympian, where they share an underwater kiss. Also in The Last Olympian when Percy and Annabeth were inspecting Athena's cabin, Percy states that "sure, she'd always been cute, but she was starting to be seriously beautiful". When Percy goes to the River Styx to bathe, he is supposed to envision the one thing that keeps him tied to the mortal world. He thinks of Annabeth pulling him out of the water at the canoe lake. Annabeth is also the only person who knows Percy's vulnerable spot. When Kronos is spotted during the battle in The Last Olympian, Percy orders a retreat, but Annabeth stays behind to help him, taking a knife that would have killed him. At the end of The Last Olympian when Luke is dying, he asks Annabeth if she ever loved him, to which she replies that she only loved him as a brother, looking up to Percy.In the second series, they are dating and shown to be in love. Several times, both Annabeth and Percy say that they cannot live without the other. They say that they love each other and kiss throughout the books. This pairing is commonly referred to as Percabeth( per- sa- beth).
