I see.
Michael and Greer didn't really want to know how Terri was doing.
There is no reason to do a test if you already know the result. Unless the test was to proove that she was not in pvs then why do it? In court, the Schindlers even admitted under oath that they knew Terri was in pvs. So what is the test for those of us like you who if the result is different than what you want will just ignore it and point to as another part of the conspiracy.
