My thoughts:
1. If it was 3:00 am and she was truly on her way to the bathroom and she saw the glow of the kitchen light and it startled her enough to go look....WHY? That would have been close enough to the time that Ronald got home from work. Why did she assume immediately something was wrong, in a groggy state of mind from waking up....because you all know when one wakes up from deep sleep to go to the bathroom...or get a drink of water...whatever...one is still groggy.
2. When she woke up to go to the bathroom, wouldn't it make sense if she were sleeping in the same bed as children her first instinct was to look at the children as she quietly got up to go to the bathroom so as to not wake them? Did she not notice right away that Haliegh was not in the bed? Sometimes kids get 'lost in the covers" so wouldn't instinct have told her if anything was questionable to reach out and pat the bundle?
3. But more importantly.......WHY all the blabber about blankets washed, etc.?? What relevance does that have? Seems to me she wasn't the type to be so concerned about the children and their blankets when the gross pillow didn't even have a pillow case on it. ya know? Do you recall AT THE ONSET she stated "I even washed the blanket on the window"? What was that about? Was a blanket on a window instead of curtains? So why at the spur of the moment...in the eve...would she have put kids to bed and grab a "curtain blanket" and washed it too? Something not right there.
4. What possessed her to become high alert and then to go towards that light? It could have been Ronald in the kitchen for all she knew coming in from work. Seems to me the bathroom is what woke her...is where she would have went first....when people lie...they give TOO much information. Her statement of "I woke up to go to the bathroom, saw the light, saw the door, and never went to the bathroom"....is what totally snagged me at the onset. It was NOT necessary to add the "I never went to the bathroom" part.
She embellished enough words in her statements about the events in that evening , in my opinion...to make a lie believable. Enough so that the investigators agree with her "inconsistencies" as being important enough that they keep bringing her back in.
