Well, if the dog did hit on TL's car it is probably because Casey got into it...on the many days that she either got a ride or drove TL's car. Very likely she had some decomposition fluid on her clothes. I wonder if there was ever a little stinkiness in either TL's car or Amy's. Didn't she drive TL's car to Jesse's the day she went to his house, looking clean, and asked to use his shower?
