Consequences. That wasn’t a real answer, so Theo waited impatiently for more.
Once he had, he wished he hadn’t heard it at all. There was white noise in his brain, because this was so much worse than he’d expected, it was insane, and he – he couldn’t just sit anymore.
Theo slid off the edge of the desk and paced a step or two away, as if the movement would dislodge the information from his head. It didn’t. He turned back to face Cash again, ashen-faced and horrified. “An unbreakable vow,” he said in disbelief, so flatly it wasn’t even a question, his chest tightening into knots the more he thought about it. What other kind of stupid Vow was there?
The – fucking Lestranges. This wasn’t normal, this wasn’t even explicable. Theo’s father had turned into a werewolf and tried to kill him once, and maybe, just maybe, that would have been an understandable reason for making an unbreakable vow... and still, even then, his father had never forced him or Cecily to swear anything to inviolable secrecy, because they were his children and that was not what people did.
But here was the proof that sometimes they did. Cash’s father knew about him. (Could never catch him again – and Theo’s questions about that were too much, too difficult to verbalise just yet; then why were we doing this?) Regardless, it was clear that Lucius Lestrange had complete control over his son, which meant Cash would have to get married and do whatever his father wanted forever, for the rest of his life. Or the rest of his father’s life, Theo amended darkly – as if just hoping Cash’s father died (or murdering the head of the fucking Wizengamot) was some kind of reasonable solution.
It crossed his mind fleetingly, but he didn’t ask out loud why Cash had never told him any of this before, because – Jesus Christ, he could guess the answer already, he knew he wasn’t taking it well. But even if he calmed down about it, he would still be stuck in it, caught in the reality and the horror of Cash’s situation... There was no escape from this conversation even if he wanted one, no escape from Cash’s life. (How had Cash lived with this since he was seventeen?)
Theo pressed the heel of his hand into his forehead for a moment, letting it fall to look at him again. “What the fuck did you swear?”
