Sooo, John cleans some gunk off her chip and she's good as new??? hmm.
And what do we make of the I love you, you love me declaration? Even if robots can't love (and we've seen her becoming more "human"...e.g., the ballet dancing) can she detect something about his feelings? The one totally trustworthy woman he can be honest with in his life, other than his mom? Interesting to see the new girlfriend coming in.
