Ginny awoke before dawn to the irritating sound of an owl tapping on her window. She looked over at Blaise as he lay asleep next to her, and sighed. So much for being a blushing schoolgirl virgin. She slipped on some clothes and let the rather large owl in, grabbing the envelope it held- addressed to Blaise Zabini. The owl settled down regally in the corner, apparently waiting for a reply. As she went to shut the window, another, more familiar owl came hurtling through, barely missing her. This one was addressed to her, in Harry's untidy scrawl. She sighed again, and left the window open.
She sat down on the bed and tapped Blaise on the shoulder. All she got was a muffled grunt, so she sat on him, "Wake up! There's an owl here for you."
He rolled over onto his back, causing her to fall. He smirked, "I wonder if there are any other blushing schoolgirl virgins in this school that I should know about?"
"Damn it Blaise, get out of my head!"
"Dream of me?"
She rolled her eyes, "No, I just had the same thought as you."
"You were thinking about schoolgirl virgins, too?"
"Ugh. Here. This came for you," she handed him the envelope while she opened her own.
Gin,
Ron and Hermione and I went up to your rooms after curfew tonight and you weren't there…
Well…Ron's pissed. It was kind of a surprise to not find you there. I sincerely hope you have a good explanation as to why we found you in a previously solid piece of wall with none other than Blaise Zabini on the map. Maybe you can't tell, but I'm restraining the urge to run around screaming WHY THE FUCK ARE YOU WITH A SLYTHERIN!?!
Instead, I'm trying to remain calm. I really, really am. I'm sure there's a logical explanation as to why my almost-sister was in a room, overnight, with a Slytherin. Actually, I'm not sure there's a logical explanation; Hermione's just trying to persuade me that there is.
Anyways. As I'm writing this we're preparing to go wait for you in that corridor-that-used-to-not-have-a-room-where-you-are-with-Zabini. Oh. Did I mention Ron's pissed?
Your loving yet very confused and worried almost-brother,
Harry"Oh fuck…" She murmured, quickly categorizing this as 'an event that would dramatically worsen the day before it started.'
"What's yours say?"
"The Wonder Trio is bloody camped outside of the wall. They know you're here. I'm so fucked."
"You're fucked? My letter was from Draco," said Blaise, as if that clarified everything, which, of course, it did not.
"Is he camped outside the door?"
"No-"
"Then I don't see how it can be wo-"
"He demanded to know why my name had stricken itself off of the records of Slytherin of its own accord," he said flatly.
Ginny threw her hands up in despair. "That's wonderful," she said sarcastically, "But Draco is not roughly ten meters away waiting to murder you. My brother is. Quick," her tone shifted to a more frantic one, "Why were we here?"
There was a moment of silence, then, "I can't believe I let you talk me into this," they said simultaneously.
Ginny sighed, "You first."
"You…I'm not a Slytherin anymore!"
Ginny snorted, "You didn't make a really good one, anyways. Muggle inventions?"
"I'm a pureblood. My parents are…involved in the Dark Arts. I'm supposed to be in Slytherin." He gestured vaguely, "Um…that's it."
"I can't believe I let you talk me into this," she waved between the two of them, feeling herself grow, at the least, faintly red.
Blaise smirked, "I don't recall that there was much talking involved, oh blushing schoolgirl."
Ginny closed her eyes. There had to be some logical way, as Harry had suggested, out of this mess. Really. Unfortunately, nothing was coming to mind. She took a deep breath and opened her eyes. To her surprise, Blaise was looking at her with concern, but she waved him off and said, a little too brightly, "Well, let's go face whatever shit we've landed ourselves in, hmm?"
And then it hit her. In all her panic, she had failed to seize upon the most reasonable answer- the one that contained bits of truth. "Wait…it's so simple. We just tell them about how I chose you to be a member of Lijanhorn, and leave out the rest!"
Blaise looked torn between amusement and amazement. Amazement won. "You stupid little girl," he said scathingly, reminding Ginny frighteningly of the one time she had seen Pierre Zabini, his father, "Of course that's we'll tell them. It's Draco I'm worried about, you dolt!"
Ginny cringed, horrified that she had been thinking of Blaise as a normal human. Lijara was right; he was every bit the Slytherin. She knew she was crap at hiding her emotions, so she didn't even try. "You have no fucking right to speak to me like that," she bit out, inwardly berating herself for attempting to befriend a Slytherin.
Blaise's features softened slightly as he looked her over, an uneasy silence hanging in the air. Eventually, he spoke. "Look…Ginny…I'm sorry? I dunno. I'm a Slytherin. We're snakes…don't tap the glass, we snap."
She thought that had to be one of the most illogical explanations she had ever heard, and she lived with Fred and George, so that was saying something. She couldn't hold grudges, and she should have known to expect something like this anyways, so… "S'alright. Why are you so bloody worried about Malfoy, though? I know he's supposed to be the 'Slytherin prince,' but…really. Isn't it a bit much?"
Blaise waved his hand dismissively, "Trust a Gryffindor to not understand…an ex-Gryffindor," he amended at Ginny's expression, "It's sort of a long story. You were right in that Draco used to be our figure head…our model Slytherin, I guess. The summer before our sixth year, no one saw him. And I mean no one. He came to school thin, bloody, and unnaturally pale. And kind of scary. No one knows what happened, but he had changed. He's a powerful wizard, and we respect him for that. No one really knows how stable he is, either. But he took a stand to not follow the Dark Lord, and spent the beginning of our sixth year convincing all of Slytherin to not follow in their parents' steps."
"You follow him because you're scared of him?"
"No, because…well, he's one of those people that's born to lead. He isn't the most down-to-earth person around, but he's powerful, and he doesn't expect fanatical devotion. He's kind of like those….what do muggles call them? Stickers that slowly reduce their addiction to drugs…Slytherin has for so long been at the whim of the Dark Lord that we…they need sort of a step down before we start dividing into factions and such. Draco was my best friend growing up, and I think he'd be happier if his friends would be just that: friends. Instead of people deferential to him. Eventually, I suppose we will be…"
"That made no sense. Oh crap…my brother!" Ginny jumped up, and pointed commandingly out the door, "Get dressed and then come meet them. Oh, and Blaise?" She paused, "I don't think that…we should happen again. Friends, alright?" She looked at him anxiously, waiting until he nodded before dashing out the door.
"Um…hi!" she said brightly. "Nice of you to worry so much, I think."
"GINNY WEASLEY-" Ron began as soon as he heard her voice, but his own voice was cut off by a flick of Hermione's wand. Hermione had a pained expression on her face, and apologized to Ron, who was being restrained now by Harry.
"Ron, quit struggling, or I'll tie you up," Hermione snapped. "Ginny, I do hope you have an explanation."
"Well, yes. Yes I do. Everyone, meet Blaise," she said as the wall shimmered and Blaise appeared. "He's the newest member of the House of Lijanhorn, and these are our dormitories."
"That's it?" Harry said.
"Yeah." Ginny nodded, and Lijara suddenly appeared next to her. "Oh, well, not entirely everything. This is Lijara, and she's our head of house."
