I agree. The kids hadn't even been there for 6 weeks. They'd only been back for a few days. My kids will run around, sweat, play outside, etc and then sleep in their sheets and they don't get "smelly" for several days (unless something bad happens, like an accident or they're sick). I fully believe that SW wouldn't have left them with "smelly sheets", she would've changed them before she left for AZ, so how did they get so bad in just 2 days? That part doesn't make sense to me, either. (I mean, it makes sense in that he was probably trying to clean away any scents they emitted after death. It doesn't make sense in the way he was trying to explain it. But then, few things do.)
