Castiel was still at the HoA after the incident with Sam, but he was up and moving around the building once again by now. His appetite had finally started to return so the angel was in the main kitchen of the house, his own kitchen empty considering everything had expired, digging through what was generally available for something he actually wanted.

Crowley's massive invisible hellhound, Growley, was at the side the entire time, watching curiously. Castiel tended to spoil her, after all, so while she was taking her job of guarding him very seriously she also was pretty sure she might get a treat out of this.
