That's the thing with Gunnar: you never really know. That's also what's so great about him. It's not that he doesn't care what other people think of him—sometimes he does care, desperately. He just can't ever do anything about it. He is too different to even realize how different he is, if that makes any sense.
Russel finds out a bit of unpredictability (emphasis on a bit) is a good thing and gets his HEA.
A nice wrap up.
