Shef landed with a dull thud, and swiftly surveying the room he'd dropped down into. His glance rested on the jacket for a moment, and he smirked. "Good job Arnold, man, knew you could do it." Shef then knelt down, and opened a small peephole portal to the area below, and began talking to the civilians as he surveyed the scene below. Perhaps simply because he wasn't used to a reassuring tone, perhaps because he was simply tired of the insanity but his voice likely came across as more exasperated than intended.
"Alright. So. First things first, we're all working with Masked Knight Gaia, me and everyone who just disappeared. You're all in danger, since there's apparently an evil being that latches onto panties. We're trying to destroy it. Simple. Weird as hell of course, but simple. Now, I need you to remove yourselves from the area, for your own safety. Best would be to go for a walk on the grounds or something, and I'll send the other servants along after you when I can get them out of the way of the fight. And actually, text me at this number if you need to come back, I'll be able tell you whether it's safe. [Insert cell number here]"
Most of this, he stated without looking away from the portal, hoping that the danger would be obvious enough to them that he wouldn't need his requiem. However, for the last bit, he looked up just to determine whether they'd gotten the number and all noted it down. If he had to, he supposed he would use his requiem to force both their flight and marking down the number. But he'd prefer not to, even if it took repeating himself once or twice.
