1x16 - The Flying Doctors

Tom sees some horrible pictures of starving kids in Africa and starts thinking of going there to help. Chris thinks they're about to get married and tells Violet - which means the whole town knows. But Tom tells Chris he's made up his mind, he'll go to Africa. The talk in the town just says Tom will leave the outback and everybody thinks he'll go into town to start his own clinic. This hurts Tom a lot, but when he tells the truth, everybody apologizes. But the whole town, especially Chris, is sad when he leaves.
