Shelke sighed as she stared across the expanse of Rosso's room. Millions of paper cups had been meticulously filled to the brim with water and set down on the floor. And Rosso's desk. It was easier to just say that any flat surface was covered with filled paper cups of water.

"And this will work?"

"This is foolproof." Weiss set another cup down and filled it. They were just finishing the doorway before they departed. "I've seen it done a million times."

"Poor Argent, having to deal with this," Nero muttered, also filling a few more cups.

"You think I'd subject her to this?" Weiss placed his hand over his chest in a truly saddened manner. "You wound me. She will be staying in our room."

"I was not informed about this part of your plan."

"Nero, Argent is staying in our room tonight so that she doesn't have to work around the prank we're about to play on Rosso." Nero merely quirked an eyebrow. "What?"

"No, nothing. I was just concerned about Argent's electronic belongings. Her belongings in general, actually. I would not put it past Rosso to soak Argent's things in a fit of rage."

"Which is why she and I packed all her stuff yesterday. Thank God she doesn't have too much stuff here."

"Well, she does live close by."

"So, if I understand this plot of yours correctly, Rosso will come in tonight and trip over absolutely everything, spilling the entirety of the water."

"Right. Most of it, anyway."

"I've also rigged a few of them." Nero pointed to several cups on the floor that had fishing wire attaching them to other cups on shelves. "When the rigged cups are upset, they'll take their attached partners down with them, soaking things she didn't even touch."

"Engaging in a round of disproportionate retribution, are we?"

Shelke turned her head to see Argent standing over the trio's crouched bodies. Weiss cracked a grin. "I don't suppose you'd believe we were decorating her room as a surprise gift."

"Whatever you've planned, you should know that Rosso is on her way back right now. She's done with classes for the day."

"Perfect. Shelke, the camera?"

"Running, from the safety of several layers of plastic wrap and Argent's overhead storage." Shelke pointed to a small lens located underneath Argent's suitcase. "Even if she throws the cups around in a rage, she won't notice the camera."

"Perfect. Lets go then."

Three days later, on a lovely Monday afternoon, Weiss had been (almost innocently) lounging in his room when a curt double knock on his door signaled a visitor. Shelke poked her head in. "Just so you know, Argent has brought the tape of that prank over." The speed with which Weiss leapt out of his chair and bounded out into Nero's room (he had the television) indicated that he had been waiting for this all weekend.

"Excited?"

"Very."

"Argent, I take it you've fast-forwarded the tape to the actual occurrence?"

"Of course."

With a small smirk, Nero deftly pressed the Play button and settled in.

The room was dark, but only for a few seconds as Rosso flicked the light on and placed one triumphant heel out into her room. As the toe of her shoe collided with some of the cups, Rosso seemed to realize what exactly had happened and drew it back. Nonetheless, her first foot set off the chain reaction. Roughly half of the cups they had laid out that day had overturned onto the floor. Some of Nero's rigged cups had gone off as well, judging by the way Rosso's head suddenly jerked up to something across the room. Finally, she (as Shelke predicted) had picked up one of the cups that she hadn't knocked over with her first step and threw it at the window across the room before giving a screech and storming out of the room.

There was a stunned moment of silence before Weiss began cackling. This set off the other three who, while not as maniacal as Weiss, were still thoroughly amused by how well the prank had gone off. Finally, the chuckles died down as there was a knock at the door. Nero got up to answer it before calling out, "Weiss! Shelke! Come here, please!"

Reluctantly leaving the couch, Weiss bounded out of the room to see what Nero wanted. Placed on the magnetic whiteboard on their suite's door was a note in loopy cursive- Rosso's distinct handwriting: "This is war, my loves."

Weiss gave a sigh, handed the note to Shelke to peruse and said, "I love my life." With that, he stalked to his room.

"Weiss, where are you going?"

"To research war tactics. You heard her. This is not over."
