I for one have always noticed that except for eye color, Nick and Trubel can be brother and (half?)sister. Is it possible that Kelly Burkhardt hid Trubel years ago and did not even tell her sister Marie? No one knows Theresa Rubel's origins...but she and Nick became close quickly. I think the possibility that she is family can account for their affection for each other.
