I don't get why if the doctors saw something in Kira which appears to be an object nothing is ever said?
If Clone HQ didn't know Kira existed who put it in there?
Was some kind of alarm triggered and the doctors told any medical information was not to be revealed to the parents?
Or is this some object from the car that they then remove and we don't see them telling Sarah about it? And it's supposed to be "how amazing, she had this thing in her from the accident and she is fine now."
