I personally don't see an issue with using the subject in the story. If the story doesn't call for it and the subject can be implied then all the best to you but in my story in particular, I needed to have that as the last word. (because if I used, Not Guilty, my word count would have been over!!!)
Good story though phileomiomai, seems to be inspired by Legend with Tom Cruise?
I agree with your point on using the word, yours and...the other guys. I went a re-read some of the stories using innocence in the story. My problem I think is I was looking at it as the point of the story was to describe or evoke innocence, but you are right, it can be spun many ways.
As for my story I actually forgot about Legend, LOL! I was inspired by a writing of Leonardo Da Vinci in relation to unicorns.
"The unicorn, through its intemperance and not knowing how to control itself, for the love it bears to fair maidens forgets its ferocity and wildness; and laying aside all fear it will go up to a seated damsel and go to sleep in her lap, and thus the hunters take it"
Funny story how I even came across this. I am playing an online game called "The Secret World" and it has these investigation missions. One of them was about unicorns and it lead me to Davinci's door.
In the world of fae creatures the unicorn and the white stag myths are the ones that speak to me the most about innocence, so I went with it.
