Major character who has only appeared on 1 page in the entire OOTS saga

[Emanick]

Panel 1-2. He wasn't there in panel 1, then in panel 2 he suddenly appeared. As far as I recall, this was the only time he did so. Therefore he only appeared in one page.


NB - I do not think this is the real answer.

That would be amusingly trollish, but, based on how we've seen Rich handle plot twists with, say, The Oracle, I don't think that's really his style of misdirection. (And yes, I get that you're not actually arguing for this.)
