1)"It's a witch trial!"
2)"Dunk the witch!" "If she weighs the same as a duck..."
3)King James is another fellow I don't know much about, so I can't say how accurately he's portrayed here.
4)"Together we shall save the souls of my people from Satan, even if it means killing them all." These people are still with us.
5)"I am King James, Satan's Greatest Foe!" And humble, too.
6)"Not witchery, but bodies possessed by alien mud." Doesn't really sound more plausible.
7)"Witchfinders United, at your service!"
Overall: Another good episode. Good to see the Doctor dealing with the fact that in certain times and places, a woman is going to be taken less seriously.
