Oh, and Lacy Brown-Love, I hope I did Leo justice.

I do not own Percy Jackson or Harry Potter.

"Platform nine and three quarters..." Annabeth read thoughtfully. "Where could that possibly be?" The group looked around frantically. Their train was leaving in seven minutes and they had absolutely no idea where the platform was. They had tried asking a staff member of the train station, but she had told them to "Get lost and stop wasting the time of grown-up people".
So, there they were near platforms nine and ten, because Annabeth believed the platform could be somewhere there, searching for a platform that most likely didn't exist. "Why, oh why, oh why, oh why did Chiron have to leave us here? He really couldn't help us just to find the platform?" Annabeth sounded desperate.

Five minutes to the train. The group of campers decided to give up and go back to camp after resting their legs. They sat on the benches, Annabeth, Percy, Rachel and Travis on the longer one and Katie, Connor and Drew on the shorter. Leo, who did not have space to sit, leaned on the wall between platforms nine and ten. Then he yelped, and was gone. "Did you guys see that?" Katie asked, "Leo just disappeared through that wall!" The others shook their heads.
"No, really! He did!" Katie said, "He just leaned on the wall like this," - Katie leaned on the wall- "and then he AAAAH!" Katie fell through the wall, just like Leo.

"Katie!" Travis shouted and jumped through the wall as well.

"Well, now it's official! Travis is in love with Katie! SO CUTE!" Drew exclaimed.

Annabeth shot her an angry look. "Your frien... uh, fellow campers just disappeared through a wall and you're thinking about love!"

"Sorry! Geez!" Drew defended herself.
Annabeth looked at the clock. Three minutes.
Then, she ran towards the wall. She disappeared as well.

"Annabeth!" Percy ran, then was gone.

"Well, since everyone's going, I'm going as well."
Connor vanished.

Drew put down her mirror and sighed. "Just when I was about to try my new mascara... oh well."
Drew walked towards the wall and jumped through.
Then she gasped. She was at the platform! She, Drew Tanaka, had just saved her group! She'd found the platform! Her smile faded when she saw the rest of the group waving to her, motioning her to come on the train with them.
"Killjoys," Drew muttered and jumped on the train.

They found an empty compartment- the last one, because all the others were filled with students coming back to school from their Christmas holidays- and sat down just as the train started moving.
"You may thank me for finding the platform!" Leo said and took a bow.
The others laughed.

Soon a lady with a cart full of sweets walked by. "Anything from the trolley, dears?" she asked, with a thick British accent. Leo, Connor and Travis jumped up. "We'll have everything!"

"Everything?"

"EVERYTHING!" The three shouted as they wheeled the trolley into their compartment.

"Leo! Connor! Travis! We can't do that!" Annabeth whispered loudly.

"Yeah, we can! We have the money Chiron gave us!" Connor said, pulling out a huge bag of gold. He paid the trolley-woman.
Annabeth waited until the woman was gone and then exploded. Not literally, of course.

"Did he give it to you, or did you steal it!?"

"We, uh, kind of took it accidentally?" Connor lied.

"You are in SO much trouble," Annabeth looked furious. She was about to say something else, when the compartment door slid open and a boy with blond hair strutted in. Not walked, strutted.

"Please don't tell me that that's the student we're here to help." Percy muttered.

"Oh, please do!" Drew said, a bit louder, eyeing the boy.

"So you are the exchange students?" the boy asked, smirking at their orange t-shirts.

"So that's what that McGonagall person told them we are..." Percy thought.

"I'm Draco Malfoy. Just letting you know that nothing in this school happens without my knowledge, so don't even try to trick, prank, tease, backtalk or steal from me."

Travis and Connor were grinning from ear to ear, plans forming in their minds as Malfoy talked.

"Got it?" Malfoy asked, then looked at Travis and Connor, "What 'you smiling at?" he asked and looked at his reflection in the window. After realizing he looked fine, he let out a sigh of relief and walked out.

"I just wanna punch that dude!" Leo said. "Whyyyyy do the blessings Hecate gave us only start working when we get to Hogwarts?" "So you wouldn't do something like that." Annabeth told him, but she was smiling, so Leo knew she wasn't angry at him.

"I think it's time to put on these robes we got from Chiron." Annabeth said a few hours later, "I think we're gonna get there soon."The campers changed.

"Yeah, and we should also try out this broom thing we got from Chiron!" Travis said, taking out a Nimbus 2001.

"Stop. Stealing. From. Chiron!" Annabeth said through gritted teeth. Then she took the broom, slid the door open and handed the broom to a random student walking by.

"Here. Take this. It's a present." Annabeth said with a smile, "Now leave." She added. The student scurried away with a big smile on his face.

Annabeth came back in the compartment. "There." she said, brushing her hands off on her robes, like the broom she had been touching was dirty. Then she gasped, because the castle came into view. "This is even better than I expected," she said staring out of the window. The campers couldn't wait to get to the castle.
