Remember the line of when Hans starts to say “We finish each others’…” then Anna finishes it by comically saying “Sandwiches!” By creating an artificial image of himself, he is able to fool Anna into thinking that he agrees, even though he is pretending.

Even though he had to sing the next line quickly, you’d think that Hans would still be confused at Anna’s change of the line. Well, here is his hidden look of bewilderment when she sings the word.

Now it comes so fast that you can’t see it too well between the frames. But once you see it here, you can clearly interpret Hans’s thoughts on Anna. In particular, mine would be something like “What did she just say? Oh man, she’s the one who is crazy!”

But then afterwards, he is able to return to the song by continuing to reel her in when he pretends to agree, “That’s what I was gonna say!”

And even with a short exchange like this, it still makes Hans appear to be too good to be true…and so Anna only continues to fall for him.
