"Ransom for a Dead Man" is an excellent title. "Butterfly in Shades of Grey" is very hard to understand.

"Ransom etc" is a great title, David, I agree. It's one of the few that's intriguing all by itself, with the seemingly irrationality it suggests. I think that's a really good quality for a title to have; sort of suggesting something vague and mysterious, then having it understood only after seeing what the episode's actually about.
