The dog tag thing is bugging me too. Why are they showing them at all? There has to be a reason. Would the average normal viewer (not us FORTers) even catch it? I can't imagine Tessa and Andy would go along with the whole "dog tag" storyline just to confuse us. I wonder what Tessa thought when she walked up and saw them laying there. Are the dog tags the "key" to the whole show? The suspense is killing me!
