If Kit were the one making the introduction, he'd probably be like "fie!!!!" with ire and a fist shake akin to if Nick had taken the last churro at Disneyland (true story, I was told to shake my fist at the 'bad people' in some play while saying 'fie' as if they had taken the last churro. The cast member KNEW how to get people to embrace the hate, let me tell you...), because, well, Nick's responsible for a lot of pain in his life.
Nick may not have ever cared for Kit, though that depends on how Nick responds to people who fit Kit's personality profile (IE: Bambis, really...). Kit probably wanted to avoid the holy hell out of Nick, and might even have more than a few bad dreams of Nick taking out his father and brother (if it happened, Kit wouldn't have seen it, but the mind is tricky and stuff).
Kit wants Nick to pay for his crimes, and in a deep, deep place in his mind, he might want to be the one to do it (it's not the place where he's a viking, though, that's super different). For now, Nick's something of a boogeyman.
