How about General Hague actually appearing in Severed Dreams?
JMS killed Hague offscreen just because Robert Foxworth dared to appear on DS9.
(well to be fair, Foxworth's agent doublebooked him on B5 and DS9 at the same time. He had to choose which one to do, so he chose DS9, which was a two-parter. Still, JMS' "revenge" seems a bit harsh....)
I always loved the irony there. Foxworth went to DS9 and attempted on that show the very thing he (rightly) accused Clark of on Babylon 5.
And he did it AGAIN on Enterprise!![]()
True.
