He could blackmail him and he would, especially knowing in a few days time he'd likely be receiving a pile of strongly-worded letters from Macmillan about how his meeting with Tatiana had not gone the way he'd expected.

(Besides, if Macmillan thought that 'destroying him' would do him any favors in his family's or society's eyes, he was wrong.)

"But what would I have to gain from that?" he said, a smile twitching at the corner of his lips, "What would I possibly have to gain from telling anyone, especially Tatiana or your brother, that you showed up at my house drunk, killed an owl, and challenged me to a duel weeks ago?" He had already hinted the latter to Tatiana, but had not said it in such plain terms. He could change that, though.

He did not want a dead Charles Macmillan on his conscious.
