They get back in the queue

"We need to get inside out of this wind," Slytherin muttered slowly, looking at her two friends.

"Yeah," Gryffindor agreed, the three of them slipping back into the queue, a couple of boys nearby paying very close attention to them, only too happy to let them cut back into the line.

You smile to yourself as you let a false sense of security creep into their minds for a few minutes, as they slowly shuffle up the queue, still a ways off from the front.
