It took Skulduggery a moment, but in the end, even he understood what Gabe and Rafe were talking about. It was a welcome change to feel like the least intelligent one in the car, especially since it didn't dampen his magnificence in any way. "I have been wondering why the Faceless Ones were from Gabe's universe every time," he agreed. "Even after casting them out to a different reality altogether. It seemed far too coincidental to be a coincidence."

Skulduggery could also imagine how their two universes 'resonated' so closely together. They were practically the same, right down to their legends of the Ancients and their Bible stories. The only real difference seemed to be that in one, the Bible stories were all true. Or at least based on fact. And then in his own, there were sorcerers, not all of whom were descended from the Ancients. It also explained fictional stories, actually. If the resonances between two universes were so similar, it made sense that one person somewhere in either universe would become inspired by them.

Did Landel know how similar Skulduggery's and Gabe's universes were, when he pulled them both in to his prison? Or was that some subtle form of divine intervention?

Either way, they had what they needed now.

"Hang on," Skulduggery interrupted with a frown. "You've told me before that it's all just - oh, I see. Very funny. How exactly are you two going to track the sounds? And if we do manage to work out exactly when he'll arrive, is there any chance you can play them before he even realises where he is?"

And, more importantly, would anyone in their home universe be able to stop Lucifer from ever leaving it again?
