Cassandra had seen the potions lab after the accident that took her mother and grandmother. That was nothing compared to the glimpses of ruin she was given as they ran for the booth. Thank Circe she hadn't had time to change from her riding clothes and boots. As it was, she was grateful Dylan was there to guide her.
Once in the contraption -- and really, there were reasons she always took the floo on normal days -- she had to resist the urge to grab onto Dylan each time the thing shuddered on the way up. By the time they reached the top, she was still alive, in one piece, and trying not to shake like a leaf in gale force winds.
"I'm fine." Physically. She looked back at the booth they'd just gotten out of, biting her lip unconsciously. "Bruised. Nothing like falling from a horse. But, there were so many... If you hadn't been there..." Cassandra shook her head, trying to regain her usual composure. "Thank you, Dylan. Are you hurt? What happens now?"
