"What did the hell did you do !" yelled Jess, the center head of the Cerberus.
The right head looked at the others a little sheepishly. "Just what we wanted to do, " said the right head softly. "Get bigger and stronger, more like the real Cerberus."
"It's not what I wanted!" snarled Jess.
"But aren't you ......I ? I mean, aren't I ...... you?," said the right head with a confused look on her face.
Jess's head was beginning to hurt again, making it difficult to think clearly. She wasn't sure if it was the effects of the potion, or just the confusing nature of her situation.
She regained her composure and said slowly, "Which potions exactly did you - I mean we - drink?"
The right head smiled and began to babble excitedly," Oh, yes. Well, I wanted to be taller, so I took some of the vial marked "Growth". But I didn't want to just be some tall beanpole so I also took some of the potion marked "Muscle"."
Jess could feel the potion beginning to take effect. Already her muscles were warm, and it felt as if they were slowly inflating. She felt her feet began to stretch, and the floor seemed to be shrinking away below her.
With great effort, Jess said patiently, "Is that all?"
The right head paused as if in thought, then suddenly expressed a look of excitement, as if she had just remembered something. "Oh yeah, almost forgot. I wanted my ears to be bigger and my hands and feet to be more like paws, so I took more of the Cerberus potion, too. It just refilled just like magic after I put the empty vial in the box," she said excitedly.
"Ohhhh yesss," said the left head in obvious pleasure, as she flexed the rapidly expanding left bicep. "Perfect. Just perfect. Exactly what I would have chosen."
"Shut up, you're not helping", said Jess slowly. As she continued to change, it was getting more and more difficult to think clearly. The sensations were overwhelming. Her body was continuing to expand, and her trapezius muscles were thickening and enlarging behind her heads. She concentrated on her right arm, and tried to examine some of the vials using her right hand. Her hands began to change, and it became difficult to manipulate the vials easily. As she searched, the pads on her fingers and palms thickened, her fingers became shorter and thicker with a much larger claw, the bones of her palm lengthened and her thumb became smaller and receded, approaching the appearance of a dew claw.
Jess knew she was running out of time, and she had few options. She could continue to look through the vials for an antidote, gambling that she would have enough time before her hands completely morphed into a paw, making it impossible to open any of the vials. She could also just try a random potion. It might make her something smaller and easier to control or - if she was really lucky - it might be something that would eliminate these bothersome left and right heads that were causing so much trouble. Finally, she could just ask Mary for some help. She obviously had more experience with these potions, and probably knew how to fix her. If she would just get out of the bathroom!
