I've not really done a lot about the cosmic realities that each of these alternate actors came from, though I suppose that Shatner's became a major thing. Google "oswald mosley" to get an idea of where the possibility could have originated... or go read up on "roderick spode." I prefer the latter, naturally.
The Mummy Slayer is not big on proportional responses, obviously. As if the cardiac sphincter wouldn't have been challenge enough...
I wonder where OO'AH-2's gone to, he seems rather quiet through all of this. It appeared that he wanted to get on with the business of matching people up to their respective timelines, and have them listening to him. They don't seem to be at the moment. :D
He's still looming over them... like a good teacher, he realizes that there's bound to be some chatter/malarkey when a new group is dropped into the midst.
