Despite her rather odd behavior at the pizza party the night before, Aziraphale was still expecting Annette to join him at the house for her first baking lesson. He and Wilson had set up the kitchen, the young doctor seeming a bit bemused over the whole arrangement, and teasing the angel about starting a cooking class. Then Aziraphale had summarily banished Wilson from the kitchen, insisting that he couldn't be expected to get anything done properly with the young doctor underfoot.
Besides, everyone knew that baking + Wilson always = food fight.

misshargrove, and
dr-jwilsonmd should he wish to get underfoot.]
