CHEMOSABE
The Lone Ranger's very faithful companion, Tonto, called him "Chemosabe," often transcribed phonetically as kimosabe or kemosabe. Chemo- refers to drugs, while -sabe indicates knowledge.
I will do anything for chemosabe, in order to ensure he will continue to provide me with the drugs I need.

A trusted friend and confidant who is also undergoing cancer-treatment.
Ranger Reid and Tonto probably remained in good health from both being outdoors in the fresh air and sunshine most of the time and apparently abstaining from any harmful substances like alcohol or tobacco, and so conceivably they would never have been in a position to call each other "chemosabe".
