"A warlock who was involved in the Salem witch trials escapes purgatory and finds a book of spells. Meanwhile, Abbie struggles to trust Frank again; and Henry has an identity crisis."
Good episode. Katrina has started to turn to the dark side of magic. Henry who looked like he might have gone good, is revealed to still be as bad as ever. And we now know that Cpt Irving is not really himself, he's a puppet of Henry's... or maybe not even Irving at all but just some facsimile Henry created. Either way he's trouble.
