[ooc: I'm going to reference the bit from your other post!]
Oliver narrowed his eyes dangerously at the boy down the hall, wondering if his choice to join the Death Eaters was due to bad parental influence or sheer ignorance. If this young man truly understood what his comrades had done in the past, would he be so willing to participate in such things? In truth, Oliver couldn't determine who was looking at him through that mask, but the other figure's obvious eagerness and desire to risk his own life made Oliver quite sure they were young.
Not that Oliver himself was all that different when it came to his age. Of course he was still young. At twenty-two, his age was almost nothing compared to previous leaders of the Order. Dumbledore himself had created the organization, and Oliver could only hope that, given time, he could grow into the leader they needed and wanted.
He was brought out of his thoughts when Hallie spoke and moved away, going to check on rooms where Muggles may not have yet made it out. He tried to keep watch over her out of the corner of his eye, but seemingly out of nowhere came a spell, and Oliver only had time to suck in a breath and turn himself sideways to avoid it.
"In case you were wondering," he pointed out, the desire to speak appearing in a moment of forced nonchalance, "that one isn't my girlfriend. But I suggest you leave her alone nonetheless." His voice had hardened to a darker, more threatening tone, but he wasn't actually sure if it would make the other man uncomfortable.
It may not have been the most brilliant plan, and it was clear that Oliver would surely regret it later. But he didn't have time to stop and think about it in the moment. Particularly considering the sound of fire that suddenly crackled in the room. The smell of it was distracting, and it took a moment for him to fully gather his wits before sending his go-to as of late, a rather simple cutting spell. Where Oliver's dueling skills were not the absolute best, his aim had been getting better recently. Augustus Rookwood and the back of his hand would surely have agreed.
So Oliver sent one towards the other man's wand arm, just hoping that it wouldn't be dodged. Right behind that, he tried a Stupefy, but his wand rejected the order, instead shattering a vase to his right. Releasing a curse loudly, Oliver held his arm up to shield his face from the flying splinters of glass. He was starting to wonder if the magic acted up when his heart rate was furious beneath his chest. It hadn't done so with Alice, though, when he needed to save her. He had no clue at that point, how to deal with the problem, so he just gripped his wand more securely and prepared for some sort of counter attack.
