It's not enough that Uther and Giles are trying to occupy the same brain space; now my brain has apparently mentally cast Colin Morgan as Harry Dresden...which naturally makes Richard Wilson Ebenezar. And then I get seriously skeeved when I realize that Margaret has taken on Katie McGrath's face, because dude, that's just wrong*. If Thomas weren't James Marsters through and through, I fear I would be picturing Bradley James when I hear him.
The above is by way of saying the combination of some of my entertainment has me feeling a bit like musical!Snape lately.
* Though honestly it's not *that* much oogier than actual Arthurian legends.
