Alina has given it all away. Her soul, her heart, her mind; everything she has all for a vision woven by a desperate, longing heart. Loss is heavy, and the consequences shattering, but when all she has left is a place within the Darkling's arms, and bound by a force she cannot - wouldn't ignore, everything becomes inconsequential. So when all she is given is forcefully taken, she locks herself away, where nobody can find her. No one but him.
Yet, she seems to have forgotten, for they are, after-all, bound; not even destiny can sever it. And neither can he. All it takes is a single spark, both shadow and light.
