Actually there is no reason for the spacing problem as I am using the same setting I used in my other stories. Blam ff.net for this problem not me. I will have this posted on my website soon and already has the correct formating.
Also there is no other chapter for this story. Use your imagination or email me and I will tell you. :)
I'm just going to say -- this needs to be fixed. You can't have your story double-spaced like that, and your other two fics are correct, so there's absolutely no reason for it to be this way.
