Dora wasn't far behind West, more excited than usual since she was gonna get to mess around with muggle things. Vacuum cleaners to be exact. Theo had said, when she'd found him after the lesson, that they were pretty boring, but to Dora, who was all magic and insanely fascinated with muggle things, they were pretty cool.

Not bothering with the lint roller at first since... well did she have to? She really didn't care for the thing and just sort of stared at it for a ridiculously-short-but-felt-long moment before coinciding since it wasn't Flamsteed's job to teach them about muggle things, but he was being super nice and doing so anyway. It was a quick sweep of her whole attire, which wasn't for quidditch playing but for watching.

"Hi, West!" She beamed at him once she was in then turned her attention to the Flamsteed. "Hey, Professor!" What WAS he doing? She caught the end of West's question, and listened while eagerly putting on all the lab attire and joining them both.

All they needed was Sarah to get started, right? Dora glanced back at the door briefly for the Gryffindor before giving the guys all her attention again.
