First - why would Chavez put Wu into all that, when she's thinking Nick isn't a grimm? Who's gonna tell her he is?

Second - Nick knows from Trubel about Chavez' interest in recruiting a grimm for whatever 'special force' she has in mind. If she returns to Portland (wich I seriously doubt is gonna happen sometime soon unless there is another FBI-related incident), I'm sure Nick will tell Wu about her. Now that Wu is in the game, why keeping further information from him? They want him to be on their side and he showed that he wants to be, too.

Ok, they probably won't tell him about the zombie-case unless they have to and Renard won't tell of his royal/zauberbiest-backround, because of his wish for privacy.

And hey, he already DID bend the rules by helping them in freeing Monroe like that. No badge, no laws, just he and his shotgun against wesen. And the captain masking all that as some sort of suicide-group and Wu didn't complain.
