There are no lines in Vala's past, only the shadows that Daniel casts there. He takes away the sharp clarity she had in the moment and blurs the edges into nothingness.
She had long ago learnt to see in darkness but then he became her sun and she could not resist turning towards his light. It blinded her and when she tried to look away she found she could no longer see, her vision tainted, so she returned to him. Returned to his light, his warmth, his love.
She stares into the light and knows one day she will burn.
