Branwen wasn't particularly fond of the Blasting Charm, as it tended to be messy, and if it didn't work it could be a bit more of a problem. So while Vicky pointed her wand at the door, she pointed her wand at the top hinge and muttered "Wingardium Leviosa" The bolt was fairly firmly in there, but she thought she saw it move a bit.
"Wingardium Leviosa," she repeated purposefully, louder and more clearly. The bolt moved more this time, but not enough to get it out. "Help me," she said, eyes still on the hinge. If two people were doing it, it had to be more effective.
