Sam couldn't help but think that Jack was doing wonders with Potter's Army, building them up to the people standing around him, and setting everything up in such a manner which seemed to prepare everyone for any eventualities, the current layout of the room seemed to be a physical testament to that, as well as all the effort that she put into it.
"I'll go first," he said, stepping forward and raising his arm. "Bloody dementor though, you know I struggle with the Patronus," he said quietly, shaking his head then focusing on the task ahead, noting where he would go well, and where he'd have try extra hard. With a quick nod to Jack and the others he muttered "Wish me luck," he said with a devilish grin, before launching into the maze of obstacles before him.
The first was the most easy of the challenges to defeat, it required hardly any effort, he'd been stunning things since early third year, so this would be nothing special, mind you, a moving target would be harder than he'd tried before, particularly with him moving as well. "Stupefy," he said, waving his wand and shooting a jet or red light at the fast approaching dummy, watching as it went wide and cursing, before firing off a second spell which hit it square in the chest, knocking it over. "Yes!" He shouted, before continuing on through the maze.
Jack might have told him it was coming, but it was still a slight shock when the cage dropped right in front of him, he himself only just missing being able to shoot straight through. He'd expected a warning of some sort before it fell, sadly his expectations hadn't been met. Looking around he couldn't spot the key anywhere, so he assumed it'd be hidden, probably requiring a slightly more powerful summoning spell than if it was out in the open. Jack had planned it well, that was for sure. "Accio key," he shouted, flicking his wand and thinking solely of the cage, so as to prevent everyone's keys flying at him. Sure enough, out flew a key which landed at his feet, enabling him to simply pick it up and open the door with it, moving further into the maze.
Next was the part he'd been looking forward to the most since Jack had run them through it, he was particularly good at Impedimenta, he'd always just had a bit of a knack for it. Running through the maze he was less surprised when the pillows sprang out (Having learnt to expect it at any time," and so he was ready for it. "Impedimenta," he cast, his wand pointed at the pillows, before pointing it at himself and casting the spell once more. Moving in slow motion he dropped to his knees.
And dropped
And dropped
And dropped
Until he hit the floor and slid... for quite a while... at the same time as raising his arms and striking the pillows, two with on hand and the last with his other, all at once, appearing on the other side of the pillow area just as the spell wore off, enabling him to jump to his feet just in time.
All at once, barely after he'd got on his feet two spells flew down the corridor at him, somehow tracking straight onto him. "Protego," he said, waving his wand and blocking the first one, "Prote-" he then repeated, but was just a bit too slow as he was knocked off his feet and rolled back a few times, thank god someone had left those pillows there on the ground.
Standing up he shook himself off, continuing down the path until a wall blocked his view. "Reducto," he said with ease, blowing the wall apart, only to reveal a dummy approaching him at high speed, dressed as something he'd thought he'd have more time to prepare himself for, the dementor.
With no time to prepare Sam raised his wand and shot the first spell that came to mind straight into the dementor, before realising that would be pointless. Focusing on something happy (Thank god this wasn't a real dementor) he pointed his wand at the "Dementor" and focused. "Expecto Patronum!" He cried, not quite getting the spell off right, but managing to produce a large white shield between himself and the creature, forcing it back until it simply backed off completely.
Feeling slightly disappointed he walked out of the maze and shrugged sheepishly at Jack, not looking all that pleased with himself. "Buggered up the patronus," he muttered disappointedly, feeling sure that everyone else would miraculously produce a corporeal Patronus, despite it being one of the most difficult pieces of magic known. Funny how all the eleven year olds could do that at this school, what an era this was.
