When she moved, Remus moved with her. He stepped backwards and sideways as she sort of...flew to the canopy in-between them, flinging another spark to her direction. That one landed at the edge of the shade. More of its siblings followed it, all with purposeful swings of his wand as the wizard hurried closer to where she once was to gain a better view of her form. He had to say, she was behaving rather strangely for a Death Eater. Had she dropped her wand somewhere?
Or was she a Death Eater? Remus had been completely convinced she was one until she called to him an inquiry and he found himself thinking about it, feet flat on the ground, wand aimed defensively at the woman up top. What had she ever done to him? That was not a question a Death Eater might throw at him, especially if she knew of his affiliation. On top of that, he had never seen a Death Eater move as she had and never one who would drop her wand in favor of...climbing. Much like a cat.
Remus gathered his breath to himself and whispered, "Lumos," to his wand so that the tip of it glowed brightly enough to provide him a better look at whatever was happening around him.
"Show me your forearms," he said to her clearly. It wouldn't pay to be reckless and if she so much as attempted to whip him, he would be sure to burn her.
OOC: Sorry for the repost but here is my final one!
