Anna's reaction to Kristoff...

...was adorable! I love how they showed that expression of her being excited, overwhelmed, a little embarrassed, and smitten.

The fact that Anna and Kristoff are still a bit shy with each other suggests that this is a longer term and developing relationship, which is a nice change from the usual 'love at first sight' and 'happily ever after' way of doing things.

Very interested to see where they go with this in Frozen 2!
