Dean didn’t like to research most days. It’s not that he wasn’t capable of it, it was just he was easily frustrated by lack of results. For this, though, he had researched for weeks. He knew where to go, what documents to bring, and what questions to ask. The weeks of work were worth it for smile that bloomed across the Castiel’s face at the sight of all the emotional support animals to choose from. Cas connected immediately with a minipig and the process to make her Cas’ went surprisingly smooth thanks to Dean’s preparation. Dean knew he had done the right thing as he watched that pig burrow into Cas’ arms and bring him down from a PTSD trigger even if he had to share a bed with the pig.
