In Plain Sight, Season 4

Mary:
[voiceover] Evolution is a funny thing, developing defense mechanisms that work solely on the element of surprise. Case study: When I was seven, Scott Halley and I caught a lizard in his backyard. The lizard was so shocked, it shed its tail in Scott's hand, at which point Scott started bawling. His dad said the tail would grow back. But before we could witness the reptilian resurrection, his parents split up and his mom moved him to Sarasota. Point is, to survive is to let go... of old habits, new friends, and to shed your tail every now and again. It leaves scars, and it isn't pretty, but if you look close enough, what is?
