(does it turn out Manrico was convicted for something? - it seems so)
Anyway, I am rooting for the Count, even though I know that by all laws of Narrativium Manrico will win (I am assuming we won't get to see the full duel though - only the effect in another act).
The artistic depiction of witches traditionally follows folklore or the portrayal derived from witch-trials, other ways to depict them are definitely on the erotic side.
