4x9 - Dr. Quinn, Medicine Woman

Dorothy, Myra and Grace realize they are quitting and they're letting Mike down, so they decide to go back. They find her injured with a broken arm. Mike can't go to the top of the mountain anymore, but she encourages the others to make it to the top for her. Meanwhile back in town, Preston plots to guild a hotel-casino with help from his ""partner"" Jake; and Robert E is bothered by an encounter with a bounty hunter.
