That raises so many more questions! None of them are relevant now but, his skull can be taken by goblins? It's detachable? His original one was sitting in a police evidence box for years? What is going on in Skulduggery's reality????

"I want you to appreciate the restraint I have right now in not asking you several dozen questions about your skull alone." He huffs, because wow, just leave out all the important juicy bits.

Instead he will go to the closed door and retrieve his leather bag of goodies so it's not sitting in the hallway suspiciously. Plus then he can get all these ties out of his pockets.

"So you are hallucinating then? Hallucinating us?" That's weirdly touching actually.
