The lantern catches her attention.

"Hold on, Ms. Ralli," Harley asked, her eyes falling on the lantern that was hung on the podium like an afterthought. That didn't fit with the rest of Ralli's obvious intention to be hidden inside the tent. "Why is this here? ...Is there a reason you need a lit lantern here, ma'am? Aren't you, um, blind?" she added. It seemed obvious just from looking at Ralli, but the sergeant carried herself so easily, it was sometimes hard to be sure.

"My friend Bella suggested I take it... Wait." The realization hit Ralli like a bolt, pulling her face into a frown. "Bella was... playing a trick on me. That lantern will make my form obvious to anyone outside, won't it?"

"Y-yes, ma'am," Harley agreed, moving to the lantern to put it out. "There." She extinguished it, plunging the tent into total darkness. "Now I-"

Suddenly, she lost her speech just like her eyesight as a hand was clapped over her mouth. She quickly realized why, as she heard footsteps in the class... Then a loud thud. "Ah, what the hell?!" Harvey had tripped over all of the books his sister had left spilled on the floor.

"I am in here! Alone!' Ralli said meaningfully. "I accidentally dropped some books on the floor when I came in. Do not come in here or I will kill you."

"G-geez... whatever you say, ma'am," Harvey growled, picking himself off the floor. "Hey, Ms. Ralli... this whole tent biz... You're really naked in there?"

"... Yes. I am naked and alone," she declared, still clamping her hand over Harley's mouth. The young knight trainee had now come to terms with the fact that she would apparently be spending the entirety of this class in a dark tent, pretending not to be there.

"... Huh... W-well! Ooookaaay then," Harvey's voice declared. It sounded more confused than aroused, which suggested he couldn't see inside the tent at all.

Ralli and Harley both remained silent as the class filed in, interrupted only by Ralli ****-threatening each student in turn if they were to look inside. Finally, everyone was seated... except, of course, for Harley Dustaine. She was still standing there with the hand clapped over her mouth (unnecessarily, since she had long-since understood what her sergeant was asking for).

"You are all here," Ralli spoke from inside the tent loudly and evenly.

"Teach! Harley Dustaine is absent," Liam spoke from his seat next to the empty one, sounding pleased. "I know you can't see from in there."

"... I know where Harley is." the teacher responded, her sense of duty to her poor captive not allowing her to claim the other woman was absent. Harley had a perfect attendance record to maintain, as a point of fact.

"Uh... Okay, Teach," the knight trainee used his favorite pet name for his teacher again, chuckling oddly. He smelled something weird in the air... He'd borrowed Harley's notes enough times to recognize her penmanship on the papers on the floor when he came in. "So, where is she? She... left her books here?"

"Well, this was fun," Harley admitted in her head. "It would have been interesting to spend the class in here, but now that Liam suspects something fishy is going on, she's going to let me out. I'll explain I just... helped her set these sheets up, or something, even though that will embarrass her a little. Her plan to protect her dignity is almost perfect... That's the last loose end she needs to take care of before she can teach a boring old class for the rest of the day..." Shamefully, Harley realized she was... maybe... hoping for something a little bit more exciting. Her actually butt-naked instructor hadn't so much as accidentally brushed against her.

Anyway, there was only one way for this to go forward.
