A new development: Gentleman Jack was not killed/sent west to die, or otherwise disposed of. And as he has been essentially replaced by Alan Mudd he decided it would be more fun, and also an improvement to his long and short term prospects, to remain in San Antonio, where at present he is stationed in my guest bedroom.
If he proves a decent roommate he is likely to stay awhile. Until a better offer comes along (probably a dame?). Let's see if he contributes to the conversation.
