In my head I have this entire backstory for Mr Hall. About how he starts dating Lisa, but is kind of wary of Dean and Castiel, mainly because he knows that Ben calls Dean 'dad' but he's pretty sure he's not Ben's biological dad. It's not that it bothers him, but he just can't work it out exactly. And when they finally tell him everything, about Hunters and angels and demons (complete with wings from Cas because he's about three seconds from walking out of the door and reporting them all to the nearest hospital he can find), he has to leave and think about it all. Because, seriously, the most he's ever had is his great aunt Agnes tell him that he should go to church every Sunday. So, yeah, he believes, but he doesn't believe, you know. Only, to have it in front of him, it's more than he can take. So, he takes some time, because this is big. Only, it all really comes down to answering one question. Is what he feels for Lisa more than the utter terror he's now feeling at being part of this family. And when he realises the answer's yes, then it's really not a question at all.
