A/N: And here is the third in the Marauder's Dawn series! I bring you, with great pride, Marauder's Quest. In this installment (if all goes as planned) we shall cover from the Marauders and Catie's final year at Hogwarts to just after James and Lily's wedding. After this there should be one more. Enjoy!

Disclaimer, I only own Catie, sorry!

Catie kissed her father's cheek. "See you, dad," she said smiling at him.

"Stay safe, princess," Charles said kissing her forehead.

"'Course," she replied, shrugging. She laughed and hugged him. "Bye."

Charles patted her back. "Good-bye." Catie pulled away and waved as she ran off towards the train, eager to see her brother and the others.

James tapped his foot against the pavement. The train was leaving in four minutes! Where was she?

"James!" a voice cried from behind him. James turned around just in time for Catie to run into him.

"Catie!" he exclaimed gleefully as he threw his arms around her. He swung her around, making Catie giggle.

"All aboard!"

James set Catie down and took her hand, pulling her to the train door. "Get in!"

Catie laughed and climbed aboard after James. "Where's the others?" James turned back to her and half smiled. She looked so…grown up, which wasn't right.

"Erm, they're in the compartment… uh, this way," he said stumbling over his words.

James cast another glance back at her and Catie raised an eyebrow. "Something wrong?"

James shook his head. "No, no, you just look…different."

Catie smirked. "I am three months older than the last time you saw me."

James smiled and shook his head. "That's not it. You're just not my little sister anymore are you? You've grown up on me."

Catie snorted and smiled at him. "I could say the same about you, you know."

James chuckled lightly. "Right, well, here we are!" He opened the compartment door and Sirius and Remus sprung to their feet.

"Blimey, James! Our little girl has grown up!" Sirius said looking Catie over.

James gave him a stern look. "Don't get any ideas."

Sirius slapped both hands over his heart. "You wound me." He looked at Catie and grinned, opening up his arms.

Catie laughed and hugged him. "It's good to see you again, Sirius."

"You too, Cate," he replied softly. When they released each other Catie moved to Remus.

She bit her lip and stuck out a hand. "Remus," she greeted dully.

Remus forced a smile and shook her hand. "Catie." James and Sirius looked at each other, eyebrows raised.

"You two aren't," James started.

"Seeing each other any more?" Sirius finished pointing a finger from one to the other. Catie smiled sadly at them and sat down.

Remus cleared his throat. "Right, well, hm, does anyone know where Peter is?"

"I bet he's lost again- or trying to woo the trolley lady," Sirius stated, whispering the last part to James. James and Sirius both burst into laughter, clutching at their stomachs. Catie made a disgusted face, having heard the comment, and looked out the window.

"There's a reason I don't like sitting in here," she mumbled.

Suddenly the compartment door opened and Peter came in. "Hi, guys," he greeted shyly, a smile on his face.

Catie lifted her face off the window and smiled. "Hello, Peter. You look very nice today."

Peter sat down between her and Remus. "Thanks, Catie."

Catie nodded and rubbed her knees. "Well, boys, that's my cue to find my friends. I'll see you at Hogsmeade."

"Bye, Cate," they said as she left.

"Where's Al?" Catie asked Lily.

"Dunno," Lily said thoughtfully, looking down the hall past Catie. Catie raised an eyebrow and looked over her shoulder. Severus stood with some Slytherins down the hall. From where the girls stood, they could just see some sleeves pulled up and hear snickers coming from the group.

Catie sighed and gently pushed Lily into the compartment. "Don't think on it too much. He betrayed us a long time ago."

Lily nodded sternly. "I know. I had seen some things this past summer… I had hoped they weren't what I thought they were."

Catie lifted her trunk up onto the bed above their seats and sighed. "Boys you just can't trust them."

"Agreed," Lily said, her eyes wandering to the compartment door.

Catie glanced down. "Don't get any ideas."

Lily sent Catie a look and the looked back. "I think Alice would disagree with us… She and Frank appear to be becoming quite serious." Catie wiped her hands on her plaid skirt and peeked out the window, letting out a small gasp. Lily ran to her side. She let out a gasp as well.

"Can you believe it!" Catie squealed.

Lily clapped her hands over her mouth. "Oh my gosh." The two turned towards each other and giggled.

Alice came in a few minutes later looking quite put out. "The new head boy caught us snogging, Frank and I… Made me come here."

"Oh dear, Lily, did you know we were such boring company?" Catie asked fighting a smile.

Lily went along with it and shook her head. "You'd think our best friend in the world would want to sit with us."

Alice huffed and sat down. "Oh come on you two."

Catie started laughing. "Caught by the head boy, eh? Remus and I," she trailed off. Her smile turned to a frown. "Never got caught," she finished quietly. Her jaw tightened as she stared at the floor. "I'll be back," she mumbled as she went to her feet and swept out of the compartment.

Lily sighed. "Oh dear."

Catie went down the train to the nearest girls bathroom and went in it, locking the door behind her. She stood in front of the sink and stared at herself in the mirror, clenching the sides of the porcelain sink. She refused to cry. No, she wouldn't cry. She looked down at the sink for a moment and then back up at her reflection. She'd give anything to be called his girl again. Her eyes welled with tears and leaned back against the wall behind her. She slid down it, starting to cry.

Alice checked her watch. "It's been an hour, Lily. You can't tell me you're not concerned now."

Lily sighed. "I'll go try looking for her. Stay here, in case she comes back."

"Sure thing," Alice said with a slight bob of the head.

Lily, after searching the James-free side of the train, put her shoulders back and went to the Marauder's compartment, hoping Catie was within. She cleared her throat when she reached the door and she pulled it open. "Do you know where Catie is?" she asked, trying to keep her voice stable.

James shrugged. "We thought she was with you."

Lily slowly nodded. "Right, thanks." She offered him a small smile and closed the door, going off towards the only place left to look. The girls bathroom.
