Lost.

 "Why do you falter fallen child? Why return to this ruin? The one you made fall?"

"To bring back what once was yours m'lady. To give you back your prize. I return back to you what once was your eye." 

"Give back what you stole from my chest as well, you horrid thief! You wretched child of the dead!" 

"I would pull my own heart from my chest if able, just to give to you what I lost."

"Give it then you shall, girl of all I lost."
