At first, I thought nothing of it, but the more I thought about it, the more it made sense. This happens in the part when Dr. Calvin says she had a man inside and she says she put Sunny's personality in a empty shell. She says that, but when Sunny goes against the other robots, he should be just like them right? because he used to have thicker alloy, but now he's in an empty shell! And it proves me right again when he goes through V.I.K.I.'s security field, wouldn't U.S.R. make their security fields strong enough to repel their own basic robot? And why couldn't V.I.K.I repel Sunny with her manual control thing?!? It is a huge slip up!!!!!!
