Yes, that's exactly what I was trying to get across. He's Cop -- and that's never going to stop. But he's also a mathematician, and that part of his brain has never quite gone into total hibernation. He may have done his best to bludgeon it into catatonia, but it's still going to come out. But he's still a homicide detective, and he's definitely in charge of this interview, and there's no way he's not going to exploit that part of his mind to get Tyler Brian to confess.

And Flack's equations may occur again. (They are the P=NP proof -- and there's at least one genius on staff who knows what that means)

I desperately want to hear that conversation in Sullivan's.

I think this Danny's smart enough not to mention it; they all have their secrets and this is obviously one of Flack's. Of course, depending on the circumstances, it could very well come up sometime in the future. (Oh. There goes the plot for Blue Blood. Go away, I'm not writing you)
