Track down Willow

Evil Willow realized where she must be - an alternate universe where Sunnydale was still protected by a Slayer. Odds were that there was a none-vampire version of herself here as well.

The thoughts of what she would do to herself sent sadistically sensual tingles down her spine.

It only took the smallest of magics to locate her doppleganger - this world's Willow was sitting out for a walk with a blond girl - hey, you add some scars to that face and the blond was probably that Slayer, Summers - and another younger girl who bore some resemblance to the Slayer. A sibling, perhaps?

As the three girls walked and chatted, Evil Willow caught how her presumably good double kept checking out the other girls without any reciprocal looks.

Evil Willow formed an evil plan - she would use a glamor to take on the appearance of one of these girls and seduce her cross-dimensional twin.
