Believe me, nothing is trivial.
Martial arts have been a part of my life for as long as I can remember.
A large part of my life revolves around my dad. Sometimes, I even feel a strong sense of connection, something very tangible when I learn something new in the martial arts.
You're dealing with a character who is, at some points, quite insane. And I hope that any wicked, dark sense of humor Eric exhibits comes out of the fact that he'd been pushed to the point where it seems quite sensible to say some of the ridiculous things he says.
