Luke was normally pretty slow on the uptake when it came to subtlety, but in this case, Lady Adler's implication ran loud and clear. He didn't bother arguing about how there were, in fact, plenty of people who would die for someone they loved, and, what's more, there were plenty of people who'd do so happily. Death wasn't the end, after all, just an opportunity for a new cycle.
It must be terrifying to think that way, Luke thought, as she jabbed her cigarette at him. Thinking that the only life you were born to was the only one you got. "Yeah," he said, his voice softened with compassion, rather than dread. "I... get that."
He leaned back his feet, not quite angling for the door just get, but looking like he was about to. "I hope you get... whatever it is that you want, Miss Adler," Luke said, surprising himself with his own sincerity. And then he turned to go.
