Eli didn't view the question as a joke and bobbed his head slowly and meaningfully. Yes, he thought it was likely for the knife to be cursed. Why else would it have made him want to doodle designs on the walls all for the purpose of catching it on fire? Why else would it have immediately sought to do the same thing to poor Jay?

The next question was: What should they do with it? Touching it seemed ill-advised. It was beyond his ken how to dispose of cursed objects, so he looked to Jay with a lost sort of expression.

After a few moments of glancing back and forth between the now hidden knife and the man, Eli decided it was high time he used his voice. There was no way he could explain where he had found it without speaking. "It's from the train." Meaning it was from the haul that certain members of the Fox Family had hauled in from the train heist. It would likely strike Jay as odd that Eli had even considered stealing from those he considered family. The allure of the knife had just been too much.
