Harry felt like he was being pulled in two directions at once. Just get to the Floo... He could see himself doing it, screaming, "Dad, get down here now!" Snape would Floo through at once, the mere tone of Harry's voice enough to signal an emergency. Taking the time to firecall his father, though, would give Draco time to slip out and get disappear into the bowels of Slytherin. Not that Snape couldn't find him, but by the time the search began, Pansy's nasty little scheme, whatever it was, might have already lured Draco up to the Owlery!
Pansy, though, wasn't the only one who could scheme. Harry was a Slytherin too, and if contacting Snape directly would give Draco too much chance to escape, then maybe there was a more roundabout way of getting the Potions Master to return to his chambers.
"I'm a seer, remember?" Harry shouted, catching up to Draco and grabbing hold of his arm again, his grip this time so tight it made his own hand ache. Draco tried his twist-and-yank move again, but braced for it now, Harry managed to hang on as he yelled, "I know things! I know the future! Your future, Draco Malfoy! Whoever's in that closet is going to take you up to the Owlery and throw you off and leave you a bloody mess at the bottom!"
That stopped the other boy cold, if only for a second. "Nobody can get thrown off the Owlery, Potter," Draco sneered. "The place is plastered with anti-gravity charms. You aren't talking to some casewitch who's never heard of rugby, you know. I know a lot about Hogwarts and its defences, so you'd better come up with a better lie than that."
So far, so good... Draco hadn't exactly gone for the bait, but Harry thought he could get him there... "It's not a lie," he insisted, raising his voice yet again. "I dreamed it, dreamed the whole thing! If you leave here, you're going to die!"
"Sure you dreamed that," the other boy scoffed. "You dreamed my death and never once thought to mention it? If you still hated me, maybe. Ha, probably not even then, you Gryffindor. But now that you don't hate me? You just don't want me leaving! You'll make up anything!"
That's it, his inner Slytherin announced. Harry would make up anything to keep Draco in the rooms, and Draco knew it, which gave him the perfect opening, the one he'd been angling for.
"I'll take Veritaserum, all right?" Just the thought of it made him shudder. While he was under the potion's influence, Draco could ask anything... and most likely would. Hopefully, though, Snape would realise what was going on long before Draco managed to find the right bottle and get three drops measured out... Harry drew in a breath, thinking this is it, time to spring the trap... "Seriously. I will. Go get some, and then you'll know. Well, what's the problem? Oh, come on! I bet you know where Severus keeps his truth potions!"
Draco was regarding him thoughtfully, at least. That had to be worth something. "If you think he keeps it where I could get a hold of it, you're barking mad. Severus knows me better than that." A slight laugh.
Harry pretended to think that one over. "Oh. Right. But remember my Lumos? If I use my wand, I bet I can find a way through the wards--"
Draco gave him a rather disgusted look. "I do remember your Lumos, yes! And I remember what followed! Severus is alerted the instant his wards are attacked, but that's what you're counting on, isn't it? You're trickier than you look!"
Draco was starting to twist his arm again. Anticipating that, Harry let go of Draco's arm just as the other boy began to yank it downwards. Caught off balance, Draco lurched on his feet, just as Harry threw himself into him, propelling the other boy backwards into the wall just beside the doorway. Harry shoved with all his might against the other boy, pinioning him chest to chest even as he glanced over his shoulder at Sals in her little box, and hissed, "Get over here, travel-fire dust!"
An urn of Floo powder yanked itself off the mantle and came sailing straight at the boys as they struggled in the open bedroom doorway.
His Seeker reflexes still honed though it had been ages since he'd played Quidditch, Harry deftly caught the urn in one hand. The idea was that he would hurl it back into the fireplace and yell for Snape, all without ever letting go of Draco, but the Slytherin boy, of course, had other ideas.
He plucked the urn from Harry's hand and flung it himself, straight against the wall behind Harry's night-table.
Harry flinched slightly as a crashing noise filled the bedroom and fine dust billowed upwards. This is spiralling out of control, he abruptly decided. The best thing to do, he realised all at once, was Stupefy his brother first and then somehow get Severus down to deal with the whole mess. Would Dobby hear him if he just yelled without benefit of Floo powder? Ha, if not, he'd just keep Draco under the hex until their father came home for the evening.
Funny, though, how reluctant he was to use magic against Draco, when he'd spent years wanting to do just that, when he'd practiced doing that very thing out in Devon. But this wasn't practice. This was for real.
Harry held his hand out, fingers pointed at Draco's face even as he planted his feet more firmly and leaned against the other boy to hold him still.
Strange though; Draco wasn't resisting nearly as much, now. He didn't even look alarmed that Harry was obviously about to cast a wandless spell straight at him. And no wonder, as Harry found out when his gaze flicked to where Sals had been.
For now, the snake was nowhere to be seen. Worse, her charmed box lay in jagged pieces, a shattered urn mixed in among them. Draco probably frightened her away on purpose so I couldn't use any magic to keep him here, Harry realised. I've been out-Slytherined. Well, no wonder, considering who I'm dealing with. But if he hurt Sals with that little stunt I'll have a thing or two to say later!
But that could wait for later.
For now, what he had to do was buy time until he could find a snake image to use. Damn! Draco wasn't wearing his student cloak, and since his own was buried somewhere in his trunk, lost in all that wizardspace, Harry was left scrambling for a solution. No doubt Draco wasn't going to wait around while Harry drew a snake!
He tried looking at his shoelace and imagining it was a snake. "Stupefy!"
Draco shoved him away and made a little show of dusting himself off. "Your need for a snake is a liability we need to address," he commented conversationally, just as though Harry hadn't just flat-out attacked him. Or tried, at any rate. Well, Draco could afford to be magnanimous, couldn't he? He didn't have to worry about Harry's magic at all, now that he'd taken Sals out of the picture. "We'll talk about it when I get back. And I will come back, Harry. I know your dreams upset you sometimes but you need to be a bit less hysterical."
"Two minutes!" Harry begged, trying not to look as though his gaze was sweeping the floor in hopes of spotting Sals.
Draco glanced at his Tempus spell and shrugged. Maybe it was his way of making up for having done that to Sals? Harry wasn't sure, but he wasn't about to waste what might be his last chance --ever-- to make Draco consider the danger that awaited him on the other side of the dungeon door.
"I know the Owlery thing is true because my dreams always come in two parts!" Harry rushed out, feeling like the words were tripping over each other, they way they were flying off his tongue. "The past first, then the future! It was a real seer dream Draco, it was. You have to believe me!"
