Thank you so much for your wonderful comment! I'm glad I was able to keep you guessing about Theo - initially, he was going to be the kidnapper, and then I ended up tricking myself and making it Gregg. I think that's why it worked so well.
I kept trying to take out some of the torture scenes, but it just seemed 'flat' and Harry's endurance wasn't coming through. I'm glad you were able to handle it and get to 'happy' part.
And I couldn't write the story without bringing Lucius into it somehow.
