I really love the library of Men of Letters, but I still miss Bobby’s small library. And sometimes I dream - Castiel re-built Bobby’s house, made Bobby’s house as his shelter and sometimes he stays for waiting for someones. I wish Castiel also has a shelter to rest his head.
Sometimes I imagine it too! I imagine how he re-builds Bobby's house by his own hands. And one day Jody founds it out and calls other locals to help Castiel. They bring tools and stuff and help him to re-build house, because they respect Bobby after zombie attack (and 'cause they respect Jody, and she can persuade anyone).
