Yeah, it certainly does seem that Angelique has acquired some powers she never seemed to have before. This raising the dead thing really takes the cake. Think of all the other times this might have come in handy. She never does it again to my knowledge.
Speaking as to the blooper, there are so many verbal gaffes on the show. This is one of my favorites because it was handled rather adroitly.
Think my favorite visual gaffe was later in this same storyline, when Angelique accidentally knocks over an obviously styrofoam tombstone. Then she tries to cover for it by automatically putting the thing back in place. Beautiful!
