Omg bless Jacob! Man oh man I can only see him becoming more obsessed with work when he realises Cas is actually alive!! Regis will be a tough cookie to crack. The fact that he is going through withdrawal from the alcohol already and on top of that he has convinced himself he killed the Prince. Regis believes that to be true, his mind is a complete mess. It's really fun to write!! Awh I can't wait for the reunion of Atlas and Cas though, I think that will be interesting to play out!
