As you look at the front porch, the MB window is directly to the left about 6 feet. Since there are easily 5 steps under that ramp which must be climbed to get to the back door, and several steps to the porch. Perhaps a very tall man could look into the window from the ground. At 5'9" I don't believe I'd be able to see into it. In either case, it draws upon serendipity that Misty chose THAT night to take the blanket down, which means someone had to either be sitting in the woods waiting for that possibility, or happened by.....they're OFF the main road, and going past there means you're going to one of only two houses on that lane. The serendipity factor for taking the blankets down and someone just being able to look in doesn't work for me, because you have to imagine all too many things to make it fit.
I stay with the simplest story, Misty's. She took down that blanket because she was suddenly without one, and she had to tell the story the way she has in order to make whatever she told the first person (Ronald) fit into what she tells everyone else:
Haleigh peed her blanket (I believe that; and I also believe she was given an edict to do her 'wifely duties' and clean it up and she hadn't)
Jr needed a blanket and her blanket was "in the van that they took" ........ gone, baby gone. So she had to take down that curtain blanket to put on Jr. She "covers Haleigh with a sheet" and does laundry.
I would love to know where that blanket from the van went. I believe we'll find Haleigh with it.
