"I suppose you don’t know that Rieux’s wife is in a sanatorium, a hundred miles or so away."
Rambert showed surprise and began to say something; but Tarrou had already left the room.
At a very early hour the next day Rambert rang up the doctor.
"Would you agree to my working with you until I find some way of getting out of town?"
There was a moment’s silence before the reply came.
"Certainly, Rambert. Thanks." (2.9.253-8)
Faced with the example set by others, Rambert realizes his duty is in fact to the town. Of course, he’s still going to leave town ASAP, but it’s a step in the right direction. Rieux, being himself, doesn’t judge Rambert, either, for any of his decisions.
