Second Draft of Defender Started

After the exhausting revision 1.5, and a few crappy short stories in-between, I have now started working on the second draft of Defender as of yesterday.  This will be the revision with doors open, that I intend for people to see.  Instead of the words "I GIVE YOU PERMISSION TO WRITE BADLY" at the top of the draft, I now have "KILL YOUR DARLINGS" in bright red.  Still trying to grasp what that means, but every little bit helps.
