Vincent needs to win to make Quinn look good. If he loses the humans will get a big head think they beat the vampires leader and their strongest. Though if Vincent manages to win since he doesn't have the shadow ability it will be a big slap to the face to the Board and humans that Quinn in their mind can win while holding back. Even if they find out he is fake they will still be embarrassed cause one of their strongest can't match a fake Quinn.
Well, I'm wondering, if you are going to fight a god, maybe you can also recruit a god. Vincent is Fighting in Quinn's place, and I'm a little curious as to how Vincent will fair, Vincent doesn't have the same Fighting style as Quinn, Vincent seems to prefer a grapling style, considering the fight discriptions we have read so far. I didn't expect Muka to win so overwhelmingly but it was a fun suprise. I'm not sure what I want to read more in the next chapter, Quinn's confrontation with Nathan or Vincent's fight with the god avatar.
