Kate and Curran are occupied with something else. Derek and Julie are on the hunt for the one who ordered the murder of a human family. This was nice and satisfying. Julie is very intelligent and I'm enjoying her test her strengths and learn her limits. For 16, she very mature and I tend to forget her age. Julie does have a crush on Derek and I'm pretty sure ditto for him. I do think he is respectful and acknowledges her age.
I do want to read more stories about Julie and Derek (ideally of an 18 or older Julie). I think they know each other so well and the respect they show each other is awesome.
