Gosh, now I have opened my mouth and can't shut up
When I heard about George going to the trunk to get the gas cans out, I think he suspected something wasn't right. He seemed hell bent to get to that trunk. WTH? Who rotates their own tires these days??? It sounded to me like just an excuse to get to the trunk.
I can just picture him opening the trunk and smelling that smell and asking Casey WTF happened. She probably had some story and begged for a month to explain the smell and that's why Cindy made the statement about had already given her a month. Casey probably figured that would give her enough to get her story straight, clean up her computer, etc.
I would like to know if George really did go to work that day and if Cindy had left work early. He was probably freaking out and called her to come home.
I don't think Casey would have been so adamant about letting her get the gas cans if that was all that was in there. She knew he would know the smell.
