"Oh, don't look at me like that! I had to do it, darling. If they had taken me back to him, I- it would not have ended well for me. I'm sorry..."

You couldn't believe that he would do this to you. You had trusted him! You had thought that through your shared adventures, Astarion and you had come to a mutual understanding. Maybe even built something along the lines of friendship...

As it turns out, you were wrong. He had sacrificed you without an ounce of remorse. Just. Like. That.
