Then my friend's wiry arms were round me, and he was leading me to a chair.
"You're not hurt, Watson? For God's sake, say that you are not hurt!"
It was worth a wound — it was worth many wounds — to know the depth of loyalty and love which lay behind that cold mask. The clear, hard eyes were dimmed for a moment, and the firm lips were shaking. For the one and only time I caught a glimpse of a great heart as well as of a great brain. All my years of humble but single-minded service culminated in that moment of revelation.
His face set like flint as he glared at our prisoner, who was sitting up with a dazed face. "By the Lord, it is as well for you. If you had killed Watson, you would not have got out of this room alive."

Kirk: If I hadn't tried, the cost would have been my soul.
