The Slytherin Snow Leopards who were attending the party were all gathered together. There were only four of them, including Leo and Marisa; the other two were Tracey and a shy-looking first-year boy.
"Where are we going?" asked Tracey.
"Somewhere secret," replied Marisa, trying to sound as much like Leo as possible. "But first, we need to meet the Ravenclaws."
There were only ten minutes left before curfew, so the students left the common room and proceeded up the stairs with extreme caution. Thankfully, they reached the statue on the third floor where the two halves of the group had arranged to meet without any incident.
There were five Ravenclaws still at Hogwarts: Terry, Morag and three first-years, two boys and a girl. They were clustered around the statue, trying to look as unsuspicious as possible, which was quite difficult when there were only five minutes until they had to be in their common rooms and none of them looked to be doing anything in particular.
"Hello," said Terry. "Are you going to tell us where we're going now?"
Marisa was momentarily surprised that he was addressing this question to her rather than Leo, but then she realised that as far as he was concerned, he was addressing it to Leo.
"I told you, it's a secret," she said. "Follow me!"
Marisa was not good with directions, and navigating Hogwarts was quite a challenge for her, so she was a little worried about leading the entire group to the Room of Requirement without assistance, but she still set off confidently down the corridor.
"Which way?" she asked in an undertone to Leo, who had moved alongside her.
"Left at the statue of Boris the Bewildered," replied Leo. "Then right, left and up three flights of stairs."
"Aren't those the ones that go somewhere different on Friday? I've lost track of days of the week a bit."
"They are. I'm pretty sure it's Tuesday today, though, so we'll be okay."
Marisa led the group (with directions from Leo) all the way to the seventh-floor corridor before gesturing to the wall. "Here we are!"
She smiled at everyone's shocked appearances and the questions: "What do you mean, here we are? It's just a piece of wall!"
Terry was trying to lift up the corner of the tapestry of Barnabas the Barmy, wondering if there was something underneath. Tracey was trying to work out whether Leo and Marisa were just messing with them and there really was nothing here, and discussing this possibility with Morag. The first-years just stood there, not knowing what they were meant to do.
Marisa finally took pity on them and marched up and down three times, thinking We need a place to party…
A door appeared. She shot the others a smug look and turned the handle, inviting everyone inside with a theatrical gesture, which was safely a thing Leo would have done (announcing "Ta-da!", her first impulse, probably wouldn't have been).
Once everyone was in, she followed them and shut the door behind them.
