The classroom is once again laid out differently than before. The comfy pillows and cushions are gone and the desks and chairs are back once again. The blackboard in the front of the class is bare and it appears that no one is even present in the room.
On top of Professor Welton's desk is a number of different picnic baskets and a single piece of parchment.
The picnic baskets are magical sealed and will not be about to be opened until they are taken to the location where class was going to be held.
So take a basket and wait patiently, Professor Welton isn't too far behind.
