Of all the characters, Nick and Adalind seem to share a similar type of arc/journey but from two sides until baby Kelly comes into the picture. They were each other's firsts grimm and wesen, both their mothers were killed, both lost and regained their powers, both "lost" their first born child temporarily and ultimately found something worthwhile in each other. If I didn't know better, I'd say the writers actually planned them from the beginning but I don't think it was.
