Wow. What a lovely comment. Thank you so much! :)
I was delighted when I got this prompt, because I'm also quite sure there were deep consequences to the trauma of Hell that Show didn't really get to explore properly and cynophobia seemed very credible to me too!
I'm so happy that the characterisations seemed right and I'm so pleased that you could picture the exact compassionate Sammy face I was talking about! Poor Dean... he took one look at that face and fled so that he wouldn't have to talk! :)
