Sorry its been a while! This one is set before they meet, so no confusion for people who actually read this before-chapter ramblyness :D

Sirius, The Accidental Matchmaker

Remus walked through the door of 12 Grimmalud Place, wincing a little as he bent over to tug his shoes off. Last night was a transformation, so he was extremely sore.

He suddenly heard yelling from up the stairs. He limped over to the bottom to try and see better.
"SIRUS, STOP! YOU KNOW I'M TICKLISH-AHHH!"

Sirius' bark of a laugh echoed down the hallway.
"You won't get me to stop that easily!"

A girl's voice shrieked and laughed, and Sirius cackled evilly.

Then a series of loud thumps started making their way down the stairs. Remus frowned, standing up taller and ignoring the dull pain that issued in his lower back when he did.

A young girl, maybe in her twenties, came tumbling down the stairs. Her hair was a bright, happy pink, but her face was contorted between laughter, pain, and anger as she crashed down each step.

Then, of course, she toppled right into Remus, sending the pair to the ground.

The girl laid, wide eyed, nose-to-nose with Remus. She blushed quite a lot.

She stayed there for a second longer, staring into his eyes, then toppled off of him, holding out her delicate hand for him to take.

"Sorry," She said, blushing some more. "Sirius is such and ass."

"I'm Nymphadora-" The girl winced, continuing. "Tonks. But I only like to be called Tonks."

Remus took her hand, standing up then shaking it. "I'm Remus Lupin. And you may call me…I really don't care what you call me."

The pair turned as Sirius came down the stairs, gasping for breath he was laughing so hard.

Remus was astonished when Tonks' hair turned a deep red, along with her eyes. It was almost like they were on fire.

"Sirius, I swear I'm going to rip you to pieces and then feed them to Buckbeak."

Remus continued to stare even when Sirius greeted him.

"How did you-?"

"Metamorphmagus," Tonks said matter-of-factly. "It saves time in the morning, but it kinda sucks being a half-breed."

"I know the feeling.." Remus said without thinking, then realizing what he said, smiled awkwardly.
"Oh! What are you?" Tonks said brightly.

Remus was glad when Mad-Eye called everyone to the meeting. "We'd better go."

Tonks gave him a questioning look, then walked in the door, Remus following.

And that is where it all began.
