"By dying." Jane said as a smirk formed on her face and the desire to fight Jeff became apparent in her fake blue eyes. Jane grabbed the sharp part of his knife and held it tightly so he wouldn't be able to attack just yet. With her other hand she easily popped open the clutch and pulled out her bloody knife. She pointed it to his heart just like he had done to her letting go of Jeff's knife and putting her bloody hand on Jeff's white hoodie and leaning forward after moving out of the knife's path in order to whisper in his ear. 

"Let's play a game Jeff. Oh how easy it would be to kill you right now but that wouldn't be fun now would it." She whispered in his ear before stepping back and smirking at him. "I want your death to be a spectacle. I want to hear you scream for mercy. Something you never gave your victims and something you will never get from me Jeff." Jane said before swing her leg up towards his hand that's gripping his knife so she can attempt to disarm him, but she knows this attack won't be successful. That's what makes there fights so interesting. They both are skilled fighters but they seem to be on the same level.
