Attic. Phoebe paces as she recites the vanquish she's composed:

A warlock is a funny thing.
He blinks from place to place.
And when we say these words to him,
His face they will erase.

"Sounds more like a limerick than a spell," is Raige's evaluation. No, you dimwit. It doesn't sound like a limerick at all. A limerick would sound more like this:

There once was a bimbo named Paige
Whose half-witted mind was her cage.
With words injudicious
And ignorance vicious,
Demian she sought to enrage.

And succeeded.

Phoebe scraps her spell and sits to begin again. Raige, meanwhile, diligently sketches out Cocky's image according to Eutwerpe's instruction. Eutwerpe also lays a little science on the two Ps on the topics of muses and art. Muses aren't responsible for an artist's drive, talent, or will, nor do they claim responsibility for the finished product. Also, "art isn't about perfection -- it's about expression." "The key," according to Eutwerpe, "is simply to love it." Can it, Eutwerpe. Fortunately, Piper enters the attic with three vials of the new potion at this moment, and I don't have to put up with the drivel spilling from the mouth of this "muse" any longer. Phoebe offers the following for Piper's approval:

[Eeevil] is a faithful foe
But good does battle best.
We witches will with these words
Waste the warlock's [Eeevil] zest.

According to Piper, the spell is "witty, but wordy." Nevertheless, it will have to do. Phoebe passes copies to her sisters as Piper distributes the vials. Raige's completed rendering of Cocky is accurate enough to allow her to summon The Mood Ring from the drawing's finger. Hey! Pipe down back there. By now you should know better than to question the dictates of The Great And Powerful Kern -- no matter how nonsensical and contrived said dictates are. Of course it's mind-bendingly asinine to believe that Raige could summon an object she's never seen from a drawing of a man she's never met. You, of course, may feel free to tear at your hair because of this. I choose to go bald naturally. Anyway, the plan is to lure Cocky to the attic by stealing The Mood Ring. Once he's there, the gals will smash the vials at his feet. The resulting explosion will irritate Cocky's eyes, depriving him of his ability to blink. Once he's thus disabled, the sisters will recite the vanquishing spell. Phoebe decides the boys need to witness their triumph. She crosses to the door, shouting Cole's name. No answer. Duh.
