Found 2 other entrys:

p176-"As blood ran over his hands, Nick let go and jumped to his feet. He was distantly aware that the red rage had taken over - he was driven by the fury of a Grimm state he'd never felt before."

P262-"...Nick kept the preassure on the creature's throat. That red haze was there, again, before Nick's eyes, and his every Grimm instinct told him to kill this Wesen - and it wasn't an instict he was inclined to fight."

I hope it's canon, but stating "based on" is regularly a sign for beeing not. Otherwise it would say "A Grimm-Novel".

On the other hand, the writer wasn't informed about every detail for sure, but I've read enough book series written by the very same person and still there're many discontinuities. Just means his editors haven't paid enough attention either. So we wait and see...

And it's always the fans that discover these things. Because we care about these little details... that's life ;)
