All chapters from this point on are Leo meeting Lou up to Charlie.

"Is Lou here yet? We need to get this flipping meeting started!"

"Annabeth, chill." Piper soothed. "Who's Lou anyway?"

"I'm Lo- 'n' I'm goin'." Leo had only caught a brief glimpse of Louisa- thick, curly raven hair pulled into a high ponytail, evenly tanned skin and glittering sea green eyes. She wore casual clothes under her armour, her helmet with the red plume under her arm, a sword and an array of knives in her belt with her quiver and bow swung over her back. She hadn't even crossed the threshold of the meeting room before swivelling on her heel and walking back out.

"Louisa!" Annabeth ordered, getting up and storming after her friend.

"No!" Jason was frowning, as if he recognised something. His memories were coming back, just bits at a time. "Why didn't ya say he was there?!"

"Who?"

"Bloody- ugh!"

"Lou, you're not making sense."

"Ya didn't say anythin' 'bout new demigods!"

"You didn't ask!"

"Jason Grace, son of Jupiter, praetor of the Twelfth Legion and Camp Jupiter."

"Lou?" Jason rose to his feet.

"NO!" Jason looked at Chiron.

"Louisa Smith?" He asked.

"Louisa Smith-Jackson, but yes, the same." Chiron looked at him curiously. "Why? Do you know her?"

"She's the world biggest pain in the ass."

"Ooh, I like her already." Jason looked at Leo as if he were crazy.

"She would skin you alive."

"Nice to know you have confidence in me." Leo muttered, pretending to sulk. He and Piper- who appeared to be genuinely sulking- followed Jason out. They caught a glimpse of Annabeth running out of the Big House, shouting after Louisa, who was refusing to do anything helpful. "Hold on…" Leo looked at Chiron. "Smith-Jackson?"

"Later." Chiron promised. Piper and Leo looked at Chiron quizzically, but he didn't elaborate, watching Louisa shout at Annabeth and Jason and anyone watching, but not in English. It wasn't Ancient Greek either, but… Latin.

Leo didn't understand Latin. He wasn't really focusing on that, focusing on Louisa instead. She had drawn her sword, her helmet discarded a few feet from her. She was glaring at Jason, as if her brother's disappearance was his fault.

"Lou, put the sword down." Jason took careful steps towards Louisa, taking his coin from his pocket.

"I knew you were trouble, but did ya listen?"

"Um…"

"I told ya 'n' ya didn't listen! No-one listens to me!"

"Mainly because you're a raving, blood-thirsty lunatic demigod who needs a strait jacket and pronto." Louisa turned her glare on Annabeth and Leo could see the raw power in those sea green eyes. Daughter of Poseidon indeed…

Annabeth shrugged. "Lou, we do listen. Sometimes." She added quickly. "But it wasn't Jason's fault. It was-"

Louisa didn't care whose fault it was, Leo saw. She just charged Jason, swinging her sword wildly and nearly decapitating him. He flipped his coin and gained his sword and was just managing to defend himself while she seemed intent on slicing him to shreds.

Beautiful, annoying, smart and violent… Leo liked her more and more by the second.

Jason deflected yet another swipe at his throat. He had known Louisa for years and the more he fought with her, the more his memories involving her came back. He remembered her temper, her stubbornness and her violent streak- and right now, all of that was nearly getting him killed.

"Chiron, do something!" Piper squeaked. "Guys, stop it!" She layered on with the charmspeak. Jason faltered, but Louisa gritted her teeth and seemed unaffected.

"She doesn't respond to charmspeak." Chiron told her.

"What? Why?" Piper despaired. Chiron shrugged.

"Louisa is… different, even by demigod standards."

"Lou, don't kill him! He can help us find Percy!" Louisa froze, like somebody had thrown a switch. The tip of her sword was just touching Jason's throat. Annabeth looked relieved, running her hands through her hair and sighing. Jason rubbed at his throat, looking annoyed, but with a layer of relief beneath it.

Poseidon's daughter turned away, leaving. Jason lowered his sword. The second his defences were down, she whirled round and cracked him across the jaw.

Leo huffed. She was yet another girl out his league.

Chiron wheeled forward and ordered Louisa to her cabin. She protested- of course- but Chiron won eventually.

"Are you alright?" He asked Jason once Louisa had stomped off.

"I forgot she hit that hard." Jason mumbled, massaging his jaw. A bruise was starting to show already. Piper looked ready to go after Louisa herself, but Annabeth seemed to have an idea that kept her in place.

"Leo, you go after her."

"Wait, what? She'll kill me!"

"No, she doesn't know you. And besides- if you tell her you're building the Argo II, she'll go easy on you." Annabeth's expression softened. "She won't admit it, but she misses her brother."

"OK." Leo sighed.

"I thought you loved danger."

"I'd marry it if I could." Leo agreed sarcastically. "Which one's the Poseidon cabin?" Annabeth pointed. "Oh, I like that one. Very nice." He jogged off after her, passing various campers who were all whispering to each other and casting wary glances after Poseidon's daughter. Storm clouds were progressively moving to loom over the camp. Leo hoped the magic boundaries kept the rain out.

He knocked smartly on the door. "Do you wanna build a snowman?" He sang.

"Who's that?" Louisa called.

"Leo." There was silence for a moment. "Santa's escaped elf."

"Oh." Leo was amazed that she had understood that. "What'd ya want?"

"Well, for starters, hi. Second, please don't kill me. And third, Annabeth sent me." The door opened then. Leo saw he was taller than her by a couple of inches and this instantly made him feel better about himself.

Then he remembered how quickly that bruise had formed on Jason's jaw. That was one heck of a whack.

"Well?" She demanded, crossing her arms and leaning against the door frame, as though she had better things to do. Being as awesome as she was, Leo thought she obviously did have better things to do than talk to him, a lowly engineer.

"Annabeth told me to tell you that we're building the Argo II."

"The what?"

"Argo II."

"Ain't that a big boat thing?"

"Yeah. We're building it and we're hopefully going to go to the other camp and get your brother back." Her anger subsided a bit then, replaced with curiosity. "Do you want to have a look? It's not finished yet, but should be soon."

"OK."

"But promise not to hit me?" She frowned. "I actually think you've knocked some sense into Jason back there." He grinned.

"'Bout time someone did." She muttered, but there was a small smile on her lips. Leo decided that was a good thing.

Hope this is OK and that the next few chapters will be a bit better. I'm still trying to find out if I've got pre-written chapters somewhere :P
