ΩΩΩ

Annabeth stared into the mirror for several minutes but the reflection didn't change. She wasn't sure how long she would have stood there if it wasn't for the sound of the hunting horn, signalling that capture the flag was about to start.

"Di Immortals."

She had no choice. Promising herself that she would figure it out later she quickly changed, grabbed the invisibility hat her mother gave her, shoved it on her head, and dashed out of the cabin. She decided that, for now, she wanted as few people to see her as possible. If anyone saw a new camper they would try to bring her to Chiron and she didn't have time for that. She and Clarisse's plan would need her if it was going to work.

ΩΩΩ

The daughter of Athena caught up to Clarisse just as the child of War started yelling at her brother, Malcolm.

"What do you mean you don't think she's coming?"

Her brother winced under Clarisse's glare, but tried his best to sound unafraid. "We tried to wake her up this morning, but she wouldn't get up. She wasn't feeling well yesterday. She's been working on the temple designs almost every night. Honestly, it's not that surprising that it finally caught up to her. I made the decision to let her rest. The Hermes cabin has all of the weakest allies. We can do this without risking Annabeth's health."

The daughter of Ares looked about one wrong word away from murder, not that that was unusual for a child of war. Before it could get that far, Annabeth decided to intervene. "Calm…" The daughter of Athena stopped and winced when her voice came out about an octave lower than usual. She cleared her throat and tried to make it sound more like it normally did. "Calm down Clarisse. I'm right here."

The daughter of War spun around, her eyes trying to find the daughter of Athena. She glared but Annabeth could see the note of relief in her eyes. "Where are you?"

Annabeth smiled. "I'm right in front of you."

The child of Ares seemed confused for a moment before understanding lit her face. "Where have you been? And why are you already wearing your hat?"

Annabeth looked down at her invisible form and grimaced. "It's a long story. I don't have time to explain it now. Not if we're going to beat Hermes."

Fortunately for Annabeth, Clarisse didn't seem that interested in asking any more questions, "Fine. Everyone knows what they need to do?" There was a collection of affirmation. The daughter of War nodded. "Alright, then let's go teach cabin 12 why they shouldn't mess with Ares!"

There was a battle cry and the demigods started disappearing into the woods, which hid them almost as effectively as Annabeth's hat. The daughter of Athena took a deep breath before she too followed her allies. Her task was as obvious as it was difficult. She was to be the one to find and steal the flag.

ΩΩΩ

The son of Poseidon was guarding the false flag, proudly displayed on top of a large rock outcropping that would be rather difficult for most people to climb. Percy had to admit it was one of the Stoll brothers more clever plans. Their real flag was hidden much further in the woods. It wouldn't fool anyone who got up close to it, but it was Percy job to make sure no one got near enough to spot the obvious fake too early. The fake only had to fool the other side long enough to revel whatever strategy they had come up with for the game. Once they figured that out, Percy could fall back to the real flag, and defend it from the next attempt. So far, his job had been rather boring. No one had yet managed to get to the clearing.

He was just about to make another round of the meadow when the son of Poseidon heard movement from the forest behind him. The son of the sea god ducked down behind a bush and listened as the footsteps got closer. His eyes roamed the forest in confusion. He could hear that someone just stepped on a branch. It sounded like it was coming from a few yards to his left, but there was no one there. There came the sounds of someone stumbling and a soft curse. Percy's eyes lit with understanding. There was only one person at camp he knew of that could become invisible at will, and he hadn't seen her all day.

He smiled as he saw the leaves on the ground move. He took a deep breath, and pounced.

ΩΩΩ

Annabeth was having a much harder time moving through the forest silently than she usually did. She had gained a few extra inches of height with her sex change, not to mention the extra width in her shoulders, and it was making her clumsy. She nearly got caught by a Hermes patrol crossing the river. Only by throwing a rock into the water a few dozen yards downstream did she manage to make it by them without being caught.

She saw a glimpse of the flag through the trees and breathed a sigh of relief. The sooner this game was over with, the sooner she could find Lou-Ellen to ask her what exactly she had been given. Annabeth had already contemplated what could have lead to the change and the most obvious answer was something cooked up by the Hecate cabin. She'd also have to ask magic's daughter whether or not this was one of their permanent curses.

Wisdom's daughter already had a pretty good idea about who had slipped her the potion. She had a feeling that there was something not right about Conner and Travis giving away their hard earned contraband for free. Now she was fairly certain she could guess why they did.

They'd better pray to their father for help when she and Lou-Ellen caught up to them. The daughter of Athena was certain that they did not get the potion by asking one of the children of Hecate.

Distracted by her thoughts, she tripped over a tree root. She cursed quietly to herself as she managed to keep from falling face first into the dirt. She was just looking around the clearing to see if any of the people who must have been guarding the flag heard her, when she was tackled from behind.

She immediately started to twist and shove at her attacker, trying to get free, but it was too little too late. They had their arms wrapped securely around her and they pinned her to the ground. She managed to twist in their hold so that she could see who had her. When she did, she was met with the playful green eyed stare of her boyfriend. She was only shocked for a second, but that was all the time it took for the son of Poseidon to knock the hat off her head.

His eyes widened in surprise. "Who are you?" Annabeth tried to use his surprise to throw him off, but Percy managed to hold on. He twisted her arm till she had to stop moving or risk having it dislocated. His eyes held an anger that had never been directed at her before. "Where did you get that hat? What have you done with Annabeth?"

The child of Athena gritted her teeth at the pain. "I am Annabeth, Sea-Weed brain."

Percy's jaw dropped open in surprise at the use of the familiar nickname. His eyes darted down the body beneath him in confusion. Annabeth blushed a little, wishing she hadn't decided to wear her cut off shorts. Usually she liked wearing them; they were comfortable and easy to fight in. However, she hadn't really expected anyone to see her in them. Not while she was…

"You can't be her. You're a guy."

The daughter of Athena rolled her eyes. Sometimes, she questioned her taste in men. Percy was amazing, but he could also be incredibly dense. "You have a firm grip on the obvious Perce. Yes, I'm a guy. I think the Stoll's slipped a potion into the drink they gave me." The son of the sea god sat there, gaping like a fish. Annabeth sighed. "Look at my eyes, you know it's me."

The hero of Olympus looked like he wanted to believe her, but his eyes kept roaming the unfamiliar body. Wisdoms daughter didn't have time to convince him. She decided that she'd just have to free herself. She gave him the most loving smile she could and, while he was distracted by that, jolted up to steal a kiss.

The son of Poseidon froze at the contact, but didn't lessen the pressure on her arm. It felt like he was about to pull away so the daughter of Athena wrapped her free arm around his neck, trapping him there. Annabeth nipped at his bottom lip. It wasn't too long before he gave in and started to return the kiss. Percy tilted his head slightly so the he could deepen the kiss. He forgot about holding her hostage and as soon as he released her arm to wrap his hand around her waist, she took advantage of the moment and flipped him off of her. He hit the ground hard and she heard the wind go out of his lungs.

Annabeth jumped to her feet and grabbed her hat off the ground. She looked around the clearing, noticing for the first time that there didn't seem to be any other guards. She frowned and looked back at the flag. It only took her a second to realize why. She shook her head and looked back at the son of Poseidon, who was struggling to get his breath back.

"Nice try Sea-Weed brain, but your fake flag isn't going to fool me."

The hero of Olympus was trying to stand but wisdoms daughter was already slipping her hat back on. Right before she disappeared she winked and blew him a kiss.

ΩΩΩ

Getting kissed by, an admittedly handsome, male version of his girlfriend had certainly thrown the son of Poseidon for a loop. Once he got his breath back, he ran for the real flag, but he was too late. Halfway there he heard the disappointed cry of the Hermes cabin. He raced for the creek and got there just in time to see his… boyfriend… being lifted on the shoulders of the Athena cabin, flag clutched victoriously in his hand.

The son of the sea god followed the group towards the fire. If anyone else realized that it was Annabeth on their shoulders, they didn't say anything. Judging by the conversations that he overheard, most people seemed to think he was a new son of Athena.

After the crowd around Annabeth dissipated a bit, Percy walked up. "Good game Wise-girl." He briefly wondered if he should call him Wise-Boy now, but it didn't have the same ring. He'd figure that out later.

The blond-haired boy spun around in surprise, "Sea-weed brain!"

Percy smiled, and a short awkward silence descended. The son of the sea god decided to break it, "So, the Stoll brothers?"

Annabeth brushed his hair behind his ear and shrugged, "Most likely. I still have to talk to Lou-Ellen to make sure, but I'm fairly confident that she'll confirm my hypothesis. Hopefully she'll be able to tell me if they have the antidote or not."

"The antidote?"

Annabeth rolled her eyes. "Well you don't really expect me to spend the rest of my life as a man, do you?"

The son of the sea god looked the son of Athena up and down, his eyes catching on the short cut-offs Annabeth so often wore, "Shame." He gave her a playful wink. "This is a good look on you."

At Annabeth's look of astonishment, Percy decided to take his revenge for the kiss in the forest. He stepped forward and wrapped his arms around the blonde's waist. Ignoring all of the watching campers, he kissed his boyfriend.

ΩΩΩΩΩΩΩΩΩΩΩΩΩΩΩΩΩΩ

Authors Note

So I must admit. I liked this story a lot more while I was writing it. I'm actually not very pleased with how it turned out, but it was the best I could do. However, what's done is done. Maybe I'll re-write it one day… but it is not this day.

Also, in case anyone was confused by the pronouns in this chapter, it's because Annabeth still considers herself a girl where as Percy sees her as a man.

So this is where I am choosing to end it. I'll leave it up to the individual reader to decide if the potion was permanent or not.

As for the Stoll brothers… once Lou-Ellen caught up to them, they spent a month as an antelope. The shelf was enchanted so that it would fall if anyone other than a Hecate camper tried to steal a potion. She found out about the theft when she found one of the vials next to her nightstand.
