Romance (CHB)

There are many different romances that appear in the Percy Jackson and the Olympians and The Heroes of Olympus 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 when Percy wakes up he describes Annabeth as a "pretty girl with princess curls". During their quest 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 tongue-tied if he could speak, hugging him underwater (after he saved her from the sirens), 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. When Percy meets Aphrodite, she makes Percy reveal aloud that the reason for going on the quest was mostly about Annabeth. 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 during the Olympian party Percy suggests they finish their dance, and she smiles and takes his hand and they dance. Percy hears a slow song and wonders what other music everyone else hears.

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 inside Mt. Saint Helens

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. Before the quest Annabeth and Percy hugged. 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, putting on her Yankees cap. 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
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, but is interrupted by Annabeth's second in command Malcolm. Percy 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. 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, saying "Hold on, Seaweed Brain, you're not getting away from me that easily," causing the cord connected to his lower back to strengthen and eventually pull him out of the river.

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".

The Lost Hero
In the The Lost Hero, it states that Percy is Annabeth's boyfriend, showing they have a romantic relationship still. Annabeth meets Jason, Leo, and Piper when she and Butch arrive to take them to camp but she really came because she was told Jason would know where Percy is. Also, she goes looking for Percy again the same day Jason, Piper, and Leo depart for their quest.

The Son of Neptune
It is confirmed in the first chapter of The Son of Neptune that besides Percy 's own name and heritage as a demigod, Annabeth is the sole aspect of his life that he can recall to any extent at that point. Not long after, Percy has a dream in which Annabeth, as well as Grover, appears telling him to "stay put". Percy has some internal confilict about leaving camp due to her warning, wanting desperately to see her, but ultimately leaves camp to complete the quest after making a promise to her that he would return. During the quest, Percy recognizes that though he wants very much to protect Camp Jupiter as well as his new friends Frank and Hazel, his drive for completing the mission relies heavily on Annabeth; he says his greatest fear is not the loss of his life, but that he might forget Annabeth's face as they get closer to Alaska. When returning to Camp Jupiter with his memory fully intact, Percy worries for his friends' saftey at Camp Half-Blood. When Juno tells him that Annabeth would be an obstacle in the coming quest, Percy gets worried for her, as well as furious at Juno for taking eight months of his life with Annabeth and his other friends. As the Argo II finally arrives, Percy realizes Annabeth must be on the boat and thinks that, despite his lost time, it would be the greatest day of his life.

Throughout the book, Percy consistently refers to Annabeth as his girlfriend, even turning down blatant courtship from the Amazon Kinzie (as well as another insinuated courtship from Reyna ) by saying he's already romantically involved. He also mentions many instances of past kissing, as well as stating that the two months he'd been dating Annabeth had been fantastic. Humorously, Percy mentions a down-side to dating the smartest girl at Camp Half-Blood: he learns things.

The Lost Hero
Jason first meets Piper on the Wilderness School bus, and once seeing that he was resting on Piper, he calls her "pretty," but he doesn't recognize her since they had never actually met at the time. Also, Piper developed feelings for Jason during the school year, but he wasn't actually there and it was all just a trick of the Mist. When Aphrodite claims Piper at camp, Jason calls her a "knockout" because she's so beautiful. They bond over the course of the quest and at the end of the book they meet at the basketball court. They don't kiss though, much to the dismay of the Aphrodite campers who were betting on that.

The Battle of the Labyrinth
Juniper is first introduced in The Battle of the Labyrinth. She is completely supportive of Grover, despite what the Council of Cloven Elders think about him.

The Last Olympian
Juniper is shown during The Last Olympian, where she is quite worried about Grover's disappearance. At the end of The Last Olympian, she hugs Grover fiercely when he is made 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.

The Titan's Curse
Rachel first meets Percy in The Titans Curse at Hover Dam. She startles him, he swings a sword at her, she thinks he's crazy, but no romantic feelings are shown.

The Battle of the Labyrinth
Rachel meets Percy again in The Battle of the Labyrinth and seems to be more interested in Percy.

The Last Olympian
In The Last Olympian, Rachel kisses Percy when he leaves for a battle, but he is confused, because he also has strong feelings for Annabeth. Percy never really reaches a decision about what he feels for Rachel. Prior to her becoming an Oracle, Rachel had mutual feelings to Percy (which offended Annabeth), but the "relationship" ended after Rachel decided that she wanted to be the Oracle. They still remain good friends.

The Lost Hero
Jason remembers Reyna after finishing his quest and her memory makes him rethink about his relationship with Piper.

The Son of Neptune
It is revealed that while Reyna did feel something for Jason, he was taken away by Juno before a relationship could happen.

The Son of Neptune
Frank and Hazel were best friends in Camp Jupiter. Frank mentions he likes Hazel a lot, trusting her with the stick of his life, while Hazel was showing her time when she was in the Underworld. When Hazel rescues Frank from the Amazons, Frank says, "You, Hazel Levesque, are entirely freaking incredible." and Hazel thinks that she would just kiss him right there, but they are to busy running from the Amazons. Later, when they reach Grandma Zhang's home, Hazel makes Frank breakfast and gives him clean clothes. Frank's grandmother thinks Hazel is Frank's girlfriend. After they defeat the giant Alcyoneus in Canada, Hazel kisses him. After that they seem to develop a romantic relationship.

The Lost Hero
When getting information from Aeolus, Mellie seems attracted to Coach Hedge and he feels the same way. He even states that she was the kind of nature spirit that he could raise a bunch of satyrs with. Mellie also is impressed with his acts of bravery (even if he causes more trouble) and claims that he is very "goatly," a kind of compliment. After Mellie helps the group escape, she gets a job with Hedge to work for Piper's father as his assistant. They begin a relationship afterward. During Piper's talk with her dad, Mellie kisses Coach Hedge on the cheek.

The Son of Neptune
When Tyson and Ella arrive at Camp Jupiter after Percy calls them, Ella tells Percy that Tyson protected her as she wasn't strong. She also blushes around him. Tyson blushes too and whispers (loudly) that he thinks she is pretty. Later, when Tyson is fighting the Earthborn, she flies around him giving information on their weak spots.

The Son of Neptune
It is revealed that while Reyna did feel something for Jason, he was taken away by Juno before a relationship could happen.
