Meanwhile, there was no predicting where Libby Rhodes might find solid intellectual ground. Tristan, naturally, was so unsettled as to topple at every possible juncture. Did he want this so badly he would kill for it? Sometimes the answer was unquestionably yes. What was being human except to crave things unreasonably? Parisa could build worlds inside a person’s mind. Tristan knew now—though he hadn’t then—that Callum, for better or worse, could destroy a person’s soul without lifting a finger. He had thought Libby and Nico were powerful—that Reina was leaking raw magic, overflowing with it to the point of near-irresponsibility—but knew nothing of himself, or where he fit among them. Admittedly, Tristan was not the most useful now, but the return on his investment might be greatest of all.
Did he even understand what existed at his fingertips? Did any of them?
Morality, what little Tristan had of it, tugged him between schools of thought, forward and backwards. “I do what’s necessary,” had been Adrian Caine’s take on most of his sins, and while it was （academically speaking） a legitimate philosophical standpoint, it was rather repugnant when left unconstrained by things like ‘mercy’ or ‘compassion’ or even ‘guilt.’ Worse, if there was one thing Tristan had always aimed to be, it was well to the left of whatever his father was.
Of course he could not kill someone; certainly not over access to a few books. （Rare ones. In the hands of the most powerful medeians he’d ever known. As part of a custom that had existed for centuries, so therefore wasn’t it…？）
（Never mind.）
In any case, if he did this—or even accepted it as a thing he could do—would he ever be able to forgive himself? Could he live with whatever remained of his conscience? Funny how quickly humans could adapt to things. He had once believed he could marry Eden Wessex and serve her father dutifully, never questioning whether he wanted more; or, as the case may have been, whether he craved it. He was starting to think his solidarity with the person he’d once been had been a much more stable time, and perhaps much healthier. It had been like regular exercise, productive diet habits, broken by a blissful, gorging binge. Now he had everything he could want; power, autonomy. Sex. Christ, the sex. And all it took was killing one person, but who would it even be? It wasn’t as if they could all agree on someone.
Unless.
“What if it were Callum?” he asked.
（Purely for the sake of argument.）
Libby frowned. “What, you mean kill Callum to save… me? The rest of us?”
“Yes.” It made Tristan anxious even to think of suggesting it, though luckily Callum wasn’t in the house. Callum’s presence, like Reina’s, was readily identifiable by excess traces of magic. With all Callum’s illusions, though, it was difficult to discern what was actively in use and what wasn’t.
“Say it was Callum on one side of the tracks, and the rest of us on the other.”
“Oh.” Libby blinked, and her eyes widened. “Well, I—”
Tristan waited, bracing himself. He wasn’t entirely sure what he wanted her answer to be. It was, to her, a hypothetical question, so it wasn’t as if this was enough to really determine her stance.
Still, he was rather taken aback when she said, “I’m not doing that.”
“What?” had been his gut response, delivered so sharply it rattled his entire aching brain from the depths of his many upsetting thoughts. “What do you mean you’re not doing that?”
“I’m not killing someone,” she said, shrugging. “I won’t do it.”
“Well, suppose you won’t have a choice,” he said.
“In the thought experiment, you mean?”
He hesitated, and then said, “Yes, in the thought experiment.”
“Everyone always has a choice.” She chewed the inside of her cheek, tapping the manuscript in her lap to the wave of something he probably couldn’t hear. “Would you?”
“Would I what?”
“Kill Callum.”
“I—” He blinked. “Well, I—”
“Or me.” She glanced at him sideways. “Would you kill me?”
“No.” No, not her. What a waste it would be for anyone to rid the world of her power, her capability. What an absolute crime against humanity. That was an easy conclusion, even if sex were not part of the equation. “No, of course not, but—”
“What did Parisa say?”
It occurred to him that Parisa had said something precisely the same, only drastically different: I’m not doing that.
