So the doctor lets her take him because she knows he has a tattoo?? That's all the proof that's needed? No documentation? Or I.D?? This may have worked in the 80's but in the age of FB all he has to do is ask to see some photos on her phone. And why is he so upset that a hot blonde wants to take him away?? No guy would react like that. If he has amnesia then he should just believe her. Stupid.
