So does Steely Dan just work as a kebab seller? He said he usually sells them for 10 rupees, so...
I can imagine Dio telling him to go kill the Crusaders, and then Dan just goes back to his shop and waits until they pass by. And then he's haggling with Joseph like an ordinary vendor while Enya watches in shock.
Also Joseph was getting five kebabs, was one of them for Enya? He's too nice.
