Turnabout is fair play in the Black Magic game, it seems, and Mike is prepared to do just that. Unfortunately, he seems to have underestimated the depravity of Eric, or how the magic might cause him to act on the other side of the fence. Apparently, a female Eric is just as perverse as a male one, only this time, they have become the target of his... paintings.
Perhaps next time, Mike will choose the target of his black magic more carefully. Though something tells me, things won't go quite according to plan, regardless of how many time he tries. I'm sure plenty of future wacky hijinks are in order as he tried repeatedly to carry out his revenge. That's how things tend to go, when made-up dark arts are involved.
