"I can't believe we're here." Yang muttered under her breath. The four girls were standing in Weiss's (spacious) closet, honest-to-God trying to find a hidden switch on one of the walls.
"Are you sure your sister didn't just put us up to this?" Yang asked, disguising her embarrassment over looking so foolish with snark.
"Yang, my sister does not joke." Weiss replied, not exaggerating in the slightest.
"I'm sure we'll get along swimmingly." Yang muttered again.
The four continued their blind groping until Ruby let out an excited squeal.
"I think I've got it!" She exclaimed, holding her finger over a specific spot on the wall as the other three gathered around.
"Well press it!" Weiss demanded.
Pushing down on the protrusion in the plaster, a panel soundlessly opened next to it.
The girls stared at it for a second, before Yang piped up.
"You have got to be kidding me."
"This is new." Weiss half replied to Yang, half said to herself.
"You live in a mansion," Yang went on "with a godforsaken secret tunnel system? Do you live in a freaking book?"
"That means we'd be living it it too babe." Blake replied.
Yang continued to grumble to herself as Weiss turned to Ruby. "Could you give us a light please? Low level."
"You bet!" Ruby replied cheerily, holding up a hand as the fingers began to flow a dull red.
Turning her head down the hallway, Weiss saw the tunnel extend into darkness. "Wonder how long it goes on." She said, trying to match it up to the mental map of the mansion in her mind.
"Note." Ruby said, drawing the attention of the other girls. Following her gaze, Weiss saw a large manila envelope with her name written in cursive along the front.
"Hm." Weiss said, doing that little noise thing we all do when pondering something. Making up her mind, she grabbed the note and gently ushered her guests outside the passage. Pressing the button again, the door slid shut. "It's from my sister. Let's see what it says." Weiss said as she walked over to her bed. Ripping it open, she pulled out two pieces of paper. Deciding to check the written part first, she read aloud:
'Dear Weiss,
If you are reading this, you have either discovered this house's hidden tunnel system, or I have told you about it. If I've told you about it, it's due to the fact that I think you've done something incredibly dangerous and am worried you'll need a quick way out. I've included a map of all the routes I've taken over the course of the year. I'm getting deployed tomorrow, so consider this me passing down the Marauder's Map to you.
Use it wisely.
Love,
Winter'
As Weiss looked up, she saw the other three studying the hand drawn map Winter had left them. "I think I can figure this out." Ruby said, not taking her eyes off of the paper.
"Good. I want us to memorize it."
"What?" Ruby shouted. "We can't do that!"
"You have to. This map could be the difference between your freedom and my father. Study the map. Learn the map. Love the map. Go into the tunnels whenever you need. See if you can find any routes off of Schnee property. Winter has given us our fighting chance at a Happy Ever After, and I'll be damned if I'm going to let us waste it."
