"Looks like we'll be trapped for a while." - Mary/Sirius

My first close contact with a Marauder boy? Other than being in the same house and year you mean? Or when I would chase Potter away from my best friend? Uhm… In my third year – Black and I got stuck in a broom closet together. A very small broom closet.

"We are supposed to be cleaning the desks, not stacking them to look like the school." Mary said, annoyance thick in her voice.

"How did you even land here in detention with me, McDonald?" Sirius asked as he focused on setting another chair down on his ever growing stack.

Her scrubbing movements halted just for a mere moment before she continued. "That is none of your business, but if you must know - I accidentally let the bouncing bulbs loose into a classroom of first years."

"Keep doing things like that, and you'll be in the running for most detentions." He said, but his laugh fell short as his stack toppled to the ground with a load bang.

Mary merely rolled her eyes and went to the next desk in her line to clean. Sirius however has other plans - he grabbed her hand and started leading her from the room.

"Hey!" She exclaimed and pulled away from his grasp. "What do you think you are doing? I'm not leaving this room."

"There is a big chance that McGonagall heard that and is on her way here. Would you rather get another detention from being guilty by association or get out of here and give me time to think of some imaginary Slytherin to blame? Your choice."

She hesitated before internally cursing and followed him out the room. They turned a few corners, and then Sirius pushed Mary inside an open door. He pulled the door closed and pressed his ear against it to listen outside.

"Black... Let me out."

"Hush."

"No. Look at me."

"What is it, McDonald?" Sirius faced her and laughed. "What's wrong? Don't want to be this close to a legend?"

The closet was so small that they were basically pressed together. Mary kept moving her hands up and down, not knowing where to hold them. "Just, let me out." She grabbed the handle and tried to open the door - just to run into Sirius when she tries to leave. "Bloody Hell. What now! It's locked."

"Looks like we'll be trapped in here for a while." Sirius grinned down at her. "You're stuck with me, love."

"This is the worse day ever." She pinched the bridge of her nose then ran her fingers through her hair.

"Hold this." He handed her a mirror that he took from his cloak pocket. "Hey, James? You there?"

"Yep. What's up?"

"What the hell, Black." She turned the mirror around, and instead of her own reflection she saw the one and only James Potter.

"Hey McDonald!" James said with a wide grin. I see you are getting along with Sirius now, huh?"

"You wish."

"Turn the mirror back around McDonald. I need to talk to him."

"What's up, mate?"

"We are stuck in a broom closet."

Mary heard a thump and the laughing sound of James. "Did he fall on the ground?"

Sirius merely nodded and smirked at her.

"Filch turned the lock around so that he could catch students shagging. I got stuck in that closet the other week with a 6th year Ravenclaw. She just used alohomora and it worked."

"Are you bloody kidding me!" Mary forced Sirius to take the mirror and took her wand out of her back pocket. "Alohomora." The door clicked and swung open. With a huff she pushed past the Marauder and his laughing mirror buddy and stormed back to the Green Houses to continue where she left off right before going to detention.
