Richard Boone seems to have been a remarkably strong man. Philip Coolidge (Aaron Murdock) is a thin man, but nearly as tall as Richard Boone, yet Boone scooped him up and carried him without noticeable strain.
(Nitpick) Apparently before visiting Lew's ex-girlfriend Mae, Paladin re-drew the Navajo symbol that he saw on Jamie's horse. The sketch he shows May is darker, sharper, and more accurate than the drawing he showed Aaron Murdock.

Hey Boy: You make the business face, I think.
Paladin: A man does what has to be done, Jamie.....or he tries. It's the only way a man can live...or die.
