Kallen frowned, glancing around the command center, wondering where everyone had seemingly wandered off to. Zero hadn't called a meeting, true, but it was unusual not to find anyone...
Her thoughts were interrupted as she spotted Tamaki, along with several other Black Knights, kneeling next to a closed doorway.
"Tamaki-" she began to call out, before her comrade shushed her quickly, pulling her down until she was pressed up against the doorframe.
"What are you-" Kallen began again, but Tamaki pressed a finger to his lips, again forcing her into silence.
'Listen', he mouthed, jerking his head to the closed doorway.
Kallen was about to question why, when a brusque, irritated and very familiar tone cut in, from behind the door.
"-sick of waking up on the floor!"
Zero? Kallen's eyes widened, and, despite herself, she pressed a bit closer to the metal.
"My, you're so spoiled, you know that. It's not my fault you keep falling out of the bed."
If her eyes had been wide before, now they were as big as saucers, and she literally clapped a hand over her mouth to keep from saying the name.
C.C.? What are they-
"Not your fault?" Zero all but snarled, pacing footsteps audible. "You pushed me off!"
"You talk in your sleep. It's disturbing," C.C.'s airy, detached voice responded tartly. "Besides, a gentleman always lets the lady have rule over the bed."
"If there was a lady-" Zero began cuttingly.
"Hmph. How rude." C.C. huffed, before continuing in a voice that was so amused that Kallen could practically see the smirk, "If it's so much of a hassle, you could always snuggle with me."
Tamaki choked audibly, as did two other Knights. Luckily, so did Zero, who also sputtered, clearly stupefied by C.C.'s comment.
Kallen bit her lip to keep from exclaiming loudly herself. So C.C. and Zero had that kind of relationship... well, she supposed it was to be expected. Behind his mask and bravado, Zero was a man, after all, and C.C. was beautiful, in a mysterious, otherworldly fashion. Why wouldn't he take her as a lover?
Still, the idea of the inspirational, brilliant leader who'd turned their ragtag band into a cohesive, deadly force being in a relationship like this, much less losing an argument with his lover...
Kallen shook her head to clear those thoughts, tugging on Tamaki's uniform, whispering hurriedly, "We should leave. This isn't right..."
"No way," Tamaki began, before Zero's angry voice cut in, so forceful that all the Knights currently crowded around the door flinched.
"Whatever. I need to go take care of something. We'll continue this later."
"Scatter!" Tamaki hissed.
Hurriedly, the Black Knights scattered, fearing retribution from their vaunted leader should they be caught eavesdropping on his personal matters.
Afterward, no one ever dared make mention of this in front of Zero, but nonetheless, once or twice when he would be talking to C.C., Lelouch would catch a Black Knight giving him a strange look and mouthing the words 'whipped'.
