I agree with everything you just said. Greg is like a genius, and I do think, especially in the beginning, Nick was slightly intimidated by it. I mean Nicky is a clever guy, but Greggo is a genius. And Nick's face always shows how he feels. I guess Nick didn't really know how to thank Greg, I mean I remember a few occasions where he's like patted him on the shoulder kinda thing, then probably thought after, 'what was that?' I agree he didn't know how to thank him about breaking cases. I think Nick will have questionned his every move in the early days, and when just something work-related, he may not be thinking of covering up, and that's when a lot of subtext we got came out, like he let his guard down discussing cases etc. And fluff is good, I like fluff Sappy Love mood, lol, it's all good..
