Romance (CHB)

There are many romances that appear in the Percy Jackson and the Olympians series.

Percy Jackson and Annabeth Chase
Throughout the series, Percy and Annabeth have shown many romantic feelings for each other; mainly in The Last Olympian, though Annabeth shows it more than Percy, and Percy (strangely enough) thinks about it instead.

The Lightning Thief
In the first book, Annabeth and Percy both feel awkward at stepping into the tunnel of love. Also, shortly after this scene Percy saves Annabeth from the spiders that are part of the trap designed by Hephaestus to catch Ares and Aphrodite.

The Sea of Monsters
In The Sea of Monsters, Annabeth begins to show slight feelings for Percy (and vice versa- though, more Percy is less than Annabeth- for now). Such as crying on his shoulder, hugging him when he changed back to human, Percy thinking he'd be tonguetied if he could speak, etc. At the end of the book, she kisses him on the cheek following their success at the chariot race.

The Titan's Curse
In the third book, Percy and Annabeth dance in the beginning, with Percy being nervous and "tried to focus on little things- the streamers, the punch bowl- anything but the fact that Annabeth is taller than me, my hands are probably sweaty and gross, and I'm stepping on her toes". After slow-dancing with her, Percy found out that Annabeth almost became a Hunter at one point, and that the option is still open. Percy is terrified that Annabeth would leave him. Annabeth wanted to go back to holding the sky so Artemis could fight, but Percy took the weight. Later, while she seemed grateful to all of the people who rescued her, she expressed her gratitude mostly to Percy. At the end Percy suggests they finish their dance, and she smiles and takes his hand and they dance.

The Battle of the Labyrinth
"She glared at me like she was about to punch me. Then she did something that surprised me more. She kissed me. 'Be careful Seaweed Brain.' Then she put on her hat and vanished. I probably would've sat there for the rest of the day staring at the lava and trying to remember what my name was, but the sea demons jarred me back to reality."

- Percy

During breakfast one day, Annabeth broke the rules and sat at Percy's table just to talk about their upcoming quest, which Percy really liked. Annabeth got extremely jealous and moody every time Percy mentioned Rachel. In Mt. St. Helens, when Percy risked his life so Annabeth could get to safety, she kissed him and disappeared. She and the rest of camp presumed he was dead, as he was stuck on Ogygia for two weeks. When he returns, Annabeth hugs him fiercely until she realized she was making a scene. She was furious at Percy for being gone so long, and when she figures out where he ended up, she gets even madder with extreme jealousy.

The Last Olympian
''"I mean, she'd always been cute, but she was starting to be seriously beautiful." -Percy'' At camp, when Percy and Annabeth are inspecting the cabins and arrive at Athena's, Annabeth begins to say something about her feelings for Percy. He finds this awkward and nervous as the rules were that demigods of the opposite gender were not allowed to be in one cabin if they are not related and changes the subject. Throughout the war, Percy and Annabeth show some definite feelings for each other. While Percy was bathing in the River Styx, he had to choose one thing to think of to keep him anchored to the mortal world. He saw Annabeth pulling him out of a Camp Half-Blood lake while calling him Seaweed Brain. When Percy was about to get stabbed at his one weak point during a battle (he would've died immediately), Annabeth intercepted the blow even though Percy never told her where his weak spot was. Percy immediately became very defensive of her, making sure no one touched her. Kronos found this interesting. When Annabeth was healing, she and Percy were talking. It was becoming a romantic moment, until a camper entered and said Grover had arrived. Every time a difficult task was at hand, Percy would volunteer either to protect Annabeth, or to ask for her help. Soon, Kronos/Luke finally comes to Olympus and Annabeth, Percy, Thalia and Grover are the only ones there to protect the ancient city. Thalia got stuck under a rock when it fell. Grover got knocked out almost immediately. Kronos strikes at Percy and paralyzes him. Then Kronos goes for Annabeth and mortally wounds her. Luke regains control of himself, and stabs himself to kill Kronos once and for all. As he was dying, he asked Annabeth if she ever loved him. She replied that she thought of him like a brother, and never truly loved him at all. Near the end, when Percy was offered immortality and life in Olympus, Annabeth was horrified that Percy would leave her, similar to the way Percy felt when she almost became a Hunter. He turns down the offer, mostly because of Annabeth, and she cries in relief. Back at camp, Annabeth has a private birthday for Percy, with a homemade cupcake. Percy confesses his vision in the River Styx. He tried to tell her how he feels about her, but Annabeth was smiling at him. Percy complained she wasn't making things easy for him, which Annabeth replied to that by putting her arms around his neck and saying that she would never make things easy for him. She kissed him then, and Percy felt like his brain was melting right through his body, and that he could stay like that forever. However, campers interrupted and picked them both up, allowing them to hold hands. They dumped Percy and Annabeth into the river, expecting them to resurface. But because Percy is the son of Poseidon, he created an air bubble around the two of them, and they shared what Percy described as "the best underwater kiss of all time". They become boyfriend and girlfriend, and when Annabeth says she wants to be an architect to make something permanent, as Percy says that they were "off to a great start." Grover says that he was Percy's best friend - "except for Annabeth", Percy replies by saying that "that's different", to which Grover agrees. As they leave Camp Half-Blood for the year, they race down the hill, and for the first time, Percy "didn't look back". In the The Lost Hero, it states that Percy is Annabeth's boyfriend, showing they have a strong relationship still.

The Lost Hero
When Jason first meets Piper on the Wilderness School bus he calls her "pretty" but he doesn't recognize her. When they get to camp and Aphrodite claims Piper he calls her a "knockout". They bond over the course of the quest and at the end of the book they meet at the beach of Camp Half-Blood and confirm their relationship even though they don't kiss much to the dismay of the Aphrodite campers who were betting on one.

The Battle of the Labyrinth
Juniper is first introduced in The Battle of the Labyrinth.

The Last Olympian
Juniper is shown during The Last Olympian, where she is worried about Grover's absence. At the end of The Last Olympian, she hugs fiercely when Grover is announced a Lord of the Wild.

The Battle of the Labyrinth
Chris is first introduced in The Battle of the Labyrinth. Percy finds Clarisse in the Big House's basement trying to comfort Chris who has been driven mad. It is shown that she really cares for him. Near the end of the book, Dionysus cured Chris of his insanity. He and Clarisse were holding hands at the camp fire.

The Last Olympian
Chris and Clarisse both appear in The Last Olympian. Clarisse refused to fight in the war, although Chris tried to convince her otherwise. They both showed up when the Ares Cabin left camp and Clarisse fought the drakon when Silena Beauregard was killed. Chris went after her to keep an eye on her.

The Demigod Files
Silena Beauregard and Charles Beckendorf have had a crush on each other for years and in The Demigod Files, they started dating.

The Last Olympian
Silena was very sad when she heard Beckendorf had died. Also part of the reason she was sad was because she had been a spy for Kronos. She said she wanted to quit, but Luke threatened that he would tell, and also told her that they wouldn't hurt Beckendorf. After Silena got killed by the drakon's poison, her soul comes to Elysium, where she and Beckendorf 'live' together.

Rachel Elizabeth Dare and Percy Jackson
Rachel first meets Percy in 'The Titans Curse' at Hover Dam, she can see through the mist, but no felling were showed. She also meets Percy again in 'The Battle of the Labryinth' and seems to be more interssted in Percy. In the Last Olympian Rachel kisses Percy when he leaves for a 'battle'. Prior to her becoming an Oracle, Rachel had mutual feelings to Percy (offending Annabeth), but the relationship ended after Rachel discovered that she wanted to be the Oracle. They still remain good friends.
