I was thinking of a Mechanicus Heirophant.  I always see the cog-boys as being the cold, impersonal types, so I thought it would be amusing to try a more social tech-priest doubling as the group's shoulder to lean on.  I've read the majority of the DH2 book, all of the player creation section, and have played DH1 a couple of times now.  From what I saw in this thread there wasn't a very big focus on social niceties.  I make no promises on being a smooth-talking ladies man, but I do promise to do my best not to get us all shot!
