alter ego

I searched for the diction, the exact words to convey the dynamic in my head:

I turned to him and said:  "There's another person who lives inside of me.  Those words -- those words I used to think were from God -- are hers, not mine.  She's the one who writes..."

My brow involuntarily chased the other one for comfort in the face of this conundrum.

"... And I think that she's the one who cries too."
