Florean felt the last traces of tension drain out of him as the lingering uncertainty about his unseen company's identity was dispelled. He felt immeasurably more comfortable, now that he knew it was Regulus. Hand still running along the wall for balance and safety in the dark, he walked carefully forward toward the other boy's voice, mentally searching for saying to say in order to keep talking, as he'd been asked. "Uh, we're not too far from the library. A corridor or two over. From what I was able to make out through the journals, it's a school-wide thing. The staircases and everything stopped moving, which I guess is connected to the fact that our wands aren't working, either." Florean shrugged, even though he knew Regulus couldn't see it.
The thunder from the last lightning strike finally sounded, a loud, almost banging sound, not at all like the far-off rumbling he was used to hearing from thunder around Hogwarts. Florean was quite sure that the sound made the wall vibrate just a bit. It was a little bit unsettling. Just how close were these lightning strikes landing? he wondered. "The professors are saying everyone should stay inside, where they are, so that no one hurts themselves. It makes sense. I mean, I'm sure some people are stuck on the staircases, and if any of them got caught at the right moment, neither the top or bottom would actually be connected to anything and you might just walk off and plummet down seven floors, in this darkness."
As Regulus apologized unnecessarily for being late, Florean could hear and sense that he had drawn very close to the other boy. "Don't even worry about it," he said, taking another step forward. "It wasn't like I was -" At that moment, Florean's hand bumped into something on the wall which, after a moment, he was able to identify as what must be Regulus's hand. Unable to help it, he placed his hand half on top of the other boy's only to quickly draw it away in shock.
"Your hand is like ice, Regulus!" Frowning to himself, he reached out, fumbling along the wall until he found the Slytherin's hand again. He told firm hold of it and, doing his best to ignore the tiny excited skip his heart gave in his chest, he placed the hand between both of his own and rubbed it a bit to try and warm it up. "Do you mind me doing this?" he asked, glad that the darkness was covering the blush he could feel on his cheeks.
