Firefly Glen do unto others, what they have done to you

Uma struggled beneath his weight, for in spite of his thin physique, he was overall larger than she was. His fangs sank into the side of her neck, drawing blood, and in that moment Uma was terrified. She had battled many in her five years of life, but she had never fought anyone while being in the weakened state in which she now found herself. His grip was just as vicious as it was relentless, and for a moment, Uma feared that she would die. She tried and tried, but could not push him away.

Suddenly the weight lifted  deom her chest, and she was no longer pinned down. A novel racket ensued, the snap of bone unmistakeable due to the throaty cries of pain and anguish which followed. Uma lie still, utterly shocked by the sudden turn of events, the chance to meet her final doom now relieved. At  last the surprise wore thin and Uma hoisted herself onto her feet. Blood oozed from her new neck wound, staining her snowy fur various shades of pink and red. 

But Uma did not care. 

She was angry, and she wished to make the agouti stranger pay for his trespasses against her. Obviously he was severely crippled, killing him would be easy. Her brow  lowered and knitted together, a horrifying snarl ripping from her throat as she threw her weight into him. This time he was the one being pinned, her fangs driven into the soft, warm flesh of his throat. But she could not take him out on her own. Hopefully the dark female who had saved her life would find enjoyment in helping Uma kill the fucker. She remained on top of him  with her teeth clamped around his jugular, but she lost her grip when he began to struggle.

She needed help. He had to die.
