Question

And Lancelot knelt down and took the king’s beloved hand in both of his and kissed it. “Good night, my liege lord, my liege friend,” he said, and then stumbled blindly from the room and felt his way down the curving stone steps past the arrow slits. As he came to the level of the next landing, Guinevere issued silently from a darkened entrance. He could see her in the thin light from the arrow slit. She took his arm and led him to her dark chamber and closed the oaken door. “A strange thing happened,” she said softly. Source: Steinbeck, John. The Acts of King Arthur and His Noble Knights.

Answer 1

I believe that the idea which is addressed in the passage above is friendship  and love.
You can see that there is a strong friendship between Lancelot and Arthur, even though Lancelot is seeing his wife behind his back. On the other hand, we can see the theme of love between Lancelot and Guinevere, even though Arthur is not aware of that.
