"Do you mind if I see your blade?" Ruby asked, holding her hand out to her new Padawan.

Weiss hesitated before nodding and handing over her lightsaber. Ruby spent a moment looking it over and feeling it out with the force before igniting the blue blade and giving it a few swings and jabs. "A fencing blade. Good against other blade users, but doesn't offer much in the way of attack power. You try to find the chinks in other's armor?"

Weiss nodded. "Yes, Master Rose. You seem to know my style just from the blade. Do you use a similar weapon?"

Ruby chuckled. "Not at all." She handed Weiss' lightsaber back to her and drew her own. "I actually use a dual blade. Since you're my apprentice I should show you something special about it."

Holding the hilt level, Ruby ignited both blades, grinning as a beam of red and a beam of black shot out of either end. Her smile faltered at the look of horror on Weiss' face.

When Weiss saw those beams, the only thought that filled her head was "Sith." She took a panicked step away from Ruby, before lighting her own saber and settling into a combat stance. She wasn't about to be trained by a Sith.

Ruby watched her padawan with concern, unhappy about her reaction. This was why she never showed the other Jedi her second blade, they always jumped to conclusions! And now Weiss probably thought she was a Sith…. Ruby struggled to suppress the tears straining to be free and extinguished her blade, hanging her head.

Weiss didn't understand what she was doing. She'd just revealed she was a Sith, and now she was putting her weapon down? The only conclusion was some sort of trick. "I'm not falling for whatever you have planned, Sith," she stated venomously.

Ruby sobbed, then turned and ran out the door, bursting into the room where Blake and Yang were still getting better acquainted. In a blur she latched onto Blake and buried her head in the fabric of her robes, sobbing pitifully. Weiss struggled to understand the sight that greeted her as she ran into the room after Ruby. Why was Master Belladonna patting the back of the Sith's head? And why was she getting a disapproving look from her?

"…Padawan Schnee, what exactly did you do?" Master Belladonna asked dryly.

"…U-um, well, I…" Weiss stuttered, surprised at the tone.

"Did you, by chance, accuse Master Rose of being a Sith?"

"…yes, master."

Blake sighed. "May I ask why you decided Master Rose was a Sith?"

Weiss shuffled under her disapproving gaze. Why was she so good at that!? "…she has a red and black lightsaber, master."

"I see. So the color of one's blade is all it takes to be a Jedi or a Sith?"

"No, master. But aren't red blades the creations of the Sith?"

"Indeed they are. Red crystals are forged in Sith temples, and aren't typically used for a Jedi's weapon. Master Rose has permission from Grandmaster Yoda to possess hers."

"I did not know, master."

"Of course you didn't. It's actually known to very few. On top of that, you reacted without thinking, and hurt your master's feelings. Now, don't you think you owe her something?" Blake said pointedly.

"…I'm sorry for jumping to conclusions and accusing you of being a Sith, Master Rose."

Weiss suddenly found herself enveloped in a hug by Master Rose. "You came back!" Ruby cried out, happiness flowing off her in waves.

Weiss didn't quite understand what she meant by that. "Master, this is not appropriate behavior!"

Blake chuckled. "I think you'll find she isn't big on appropriate behavior."

"Imagine when she first sees Ruby electrocute something," Yang says quietly so only Blake can hear.

Blake snorted in laughter at the thought.
