None of the references made by the demon spark any sort of bell of recognition within Aziraphale. He's only ever seen a very paltry amount of television over the years and most, if not all of it, has been at the behest of Crowley himself. Definitely not enough to know more than a handful of names related to it. As it stands, he listens to Crowley casually rattle off his list of names patiently as he always does when he starts getting onto a tangent.

He can assume well enough that he's trying to list names of popular detectives. Investigators? Something within that area.

"Tango is such an odd choice for a name," he says absent-mindedly. As if he had any right to judge.

The idea of investigating this together did sound appealing to him, however. He has been doing a great many things during his days, mostly to ensure they had regular funds, but wouldn't it be thrilling to do something just for the sake of knowledge and excitement? Particularly if his partner was going to be Crowley?

"I'll start making inquiries. Do you think anyone at your academy might know a thing or two?"
