"Who is Ruby?" Lavender asked, her nose wrinkling in confusion. Apparently Emma knew someone named Ruby who was also a werewolf... Maybe these two different realms they came from weren't so different after all if they both contained magic and werewolves.
She supposed whoever Ruby was wasn't all that important right now, though, because at Emma's mention of time, Lavender was brought back to reality. "Er, I've never done it like this before. Usually I take a potion. I--I actually have the potion. But only enough for one month and I don't know how long we'll be here. Seems like I should save it in case things get worse. I figure if I'm locked up and kept away from everyone, then it should be okay." Even if her transformation would be even more hellish than usual.
"I should be in there before night fall. The sooner the better, actually, as I've no idea what exact time the full moon rises tonight."
