He didn't actually say no.
I believe he didn't say no because I was wrong about the Blue Carbuncle and he didn't correct me. I told him it was nixed, he did not say it wasn't nixed, and then I found out the Carbuncle in the picture was actually a Blue Carbuncle.
So I'd say he's in full poker face here and not to be taken at face value. I won't go into semantics in this thread, I'm only asking that the quote not be summarized as, "No."
