Aside from being a tad morose, “Blood Magic” is an entertaining and engaging episode, topped off with a bit of frustration aimed at Eve (Elizabeth Tulloch). She enjoys tempting fate and taking risks all by herself. Eve’s self-sacrificing attitude annoys me but it might be the guilt she suppressed over killing Nick’s (David Guintoli) mother and what not when transitioning from Juliette to über Hexenbiest Eve. “Blood Magic” has a tragic story―a pseudo ‘case of the week’ type of tale, if you will―involving aging Wesen with dementia and Alzheimer’s. This is sure to spur on the waterworks, so grab some tissues.
