As pain and a sort of satisfaction that Isopia did not have the emotional capability to understand crossed Virgil's face, she once again felt the slick, dark feeling of regret rising up like water in the back of her mind.

She was going to kill him, and although logically she could find no fault in his request, something was still nagging her to stop.

But what? What could it be? Fretfully as the stallion gasped and an audible representation of his pain exploded from his lips Isopia searched her mind, trying to find the kernel of knowledge which could explain the hesitation broiling inside of herself. She had killed before, on more than one occasion. She'd even taken the life of an innocent, unborn child. The Mountain was already a monster; she was precisely the sort of demon that Virgil wanted and needed, so what was -

A ghostly apparition appeared at the stallion's side, brandishing a sword made from bone. Although Isopia knew that the stallion had intended to fight back - he had explained that his victory could not be passively attained - she had not been expecting this. 

With a quick and shallow inhale, Isopia tried to allow her mind time to calculate what her best defense was. She seemed to be forced between stumbling into his flailing foreleg, or being struck by his sword. Obviously, despite her relative lack of battle-know-how, she opted for the former. Evading the ghostly demon's sword sent her directly into Virgil's outstretched hoof. She felt the side of his hoof graze down her neck and then jarringly move outwards as it struck her shoulder. A dull line of pain pulsed down her neck and the swell of her shoulder, and although Virgil's attack would not leave a bruise, it would certainly leave her stiff tomorrow, and certainly for the rest of this battle. 

With her momentum already propelled to the side due to her doge of the sword, Isopia allowed her weight to continue to shift to her forehand. Her long and lean body tried to angle itself towards Virgil, so that her hindquarters might be in front of him. With her weight still forward, Isopia tucked her nose towards her chest and bucked. Her goal was to send her hind legs careening towards his face, neck or chest. As soon as her limbs fully stretched out, she retracted them and tried to trot a few steps forward and turn around, not wanting to be caught off-guard while there was a sword-wielding demon around. 

"I didn't realize you'd be calling in aid." Isopia nearly scoffed before controlling the tone of her voice. Her golden eyes narrowed as she looked at the sworded-creature, trying to decide the level of sentience it possessed, or its level of dependence on Virgil.
