"On the contrary, they're exactly why I killed him," Lucifer replied, his voice quickening. "Why else would I have killed my brother? You think I wanted to?"
His expression turned to one of annoyance as he continued. "He got my attention with one of his bloody, relevant patterns, letting Chloe get in a car accident. Because when I made my deal with my father, I was bargaining for the detective's life. That much should be obvious."
At least, it was to him, that the one reason he'd ask his father for any favors would be to save Chloe. A bitter laugh escaped his throat as he added, "Maybe it's better for her that I'm gone, as she was always on the verge of dying when I was around."
Staring intently at the wall, he continued. "I was supposed to bring my mother back to hell or lose Chloe, but I was tired of playing by my father's stupid rules. He didn't ever explicitly say that was the deal, because he never actually says anything, does he? He just drops hints, gives you visions, but never tells you what he wants because that would be too easy."
As he continued speaking the edge to his voice grew. "So I thought Uriel was there to deliver my mother back to where she belonged. Instead... Instead he had with him my sister Azrael's blade."
Which would have meant nothing to Beckett, but Lucifer's eyes were wide as he recalled that moment. That maddening realization of what his brother had intended to do.
