So while Nicky is more quiet, he definitely is extremely protective of Joe, I mean we all saw how he lunges for Merrick when Merrick was stabbing Joe right?

So I wanna see a scenario where they're on a mission and the big bad guy is holding Joe hostage and Joe gets hurts

And the second Joe is hurt, Nicky is absolutely feral, trying to get the bad guys away from Joe and get Joe to safety and clings to him for days in end because while they are immortal, Nicky can't stand the thought of Joe being gone for even a second
