Assuming Renard knows he’s working with black claw (and I’m drawing a blank as to what ep he found out, help?) it’s possible that he is working with Black Claw so he can take them down… now if that is the case he should have told SOMEBODY what he was up to. there’s no evidence for that story arc that I’ve seen but it does sound like a Renard thing to do. (part 1 of 2)

(part 2 of 2) Also Renard is REALLY firm that he isn’t a Hexenbeist so maybe he doesn’t have the same issues with his beist side along with the lack of abilities that we’ve seen. Mind it could simply be a gender thing but still I’d really like the show to clarify either way. Also using their beist as an excuse for hurting/killing reminds me of people using mental illness as an excuse and as a mentally ill person I"m finding it insulting… Am I the only one who noticed that?

Renard realized Rachel and Co. were with Black Claw the minute he found out she was part of the plot to kill Andrew Dixon (near the end of “Into the Schwarzwald”), because he knew, via Eve and Meisner, that the man who killed Dixon was a Black Claw operative, as was Lucien, who met with Renard shortly after he confronted Rachel.

And honestly? I would love for that possibility (that he’s working to take them down) to be correct, because otherwise what he’s doing really doesn’t make much sense to me.

I mean, even if he’s trying to take them down, it doesn’t make much sense, but at least it wouldn’t feel like a slap in the face to four and a half years’ worth of character and relationship development. I’m also fine with the notion that he’s with them in order to get Diana back, except that I can’t figure out why he wouldn’t have just trusted Nick and Hank with that information.

As for the mental illness parallel, you’re not the only one to make the comparison. I’ve definitely seen a few different Grimm fans mention that the way the show treats hexenbiest powers seems like a metaphor for mental illness. Although not a very good or well-handled one.

I think they’ve mixed their metaphors too much on this one, personally. Do hexenbiest powers change who a person is? Or don’t they? Who knows! I mean we’ve seen at least two hexenbiests who weren’t doing damage left and right (Henrietta and Elizabeth) and we’ve also seen Adalind do just as much damage while her powers were completely gone as she did when she had them. Not to mention that at the moment she’s just about the nicest she’s ever been, and she has her powers.

Sometimes it does seem to me like a general (and stigmatizing, and again, poorly-handled) mental illness metaphor. At others it seems like they’re treating it like classic possession…with the whole floating “evil spirit” thing that left Adalind when she was de-powered in season one and then re-entered her when she performed the ritual to get her powers back.

And then at still other times it seems like it’s very specifically a metaphor for addictive disorders, with the powers themselves being the object of the addiction rather than the illness itself. But even that breaks down depending on which hexenbiest we’re talking about, and when.

Then again you have characters insisting that being a hexenbiest fundamentally changes you, while having your two principle hexenbiests treat what they did during that time in totally different ways: Adalind doesn’t shy away from responsibility for the things she did, she apologizes for them and expresses regret and a wish to undo those things.

Eve, on the other hand, has distanced herself from Juliette and the things she did as completely as possible, deflects responsibility, and claims to feel no regret or remorse for any of it, although that in itself could be due to a separate mental illness (PTSD, dissociative identity disorder, maybe both).

All this to say that no, I’ve never thought of the whole “the biest made me do it” thing in that light, but that doesn’t mean it’s not a valid interpretation or that your feelings about it aren’t valid. It just means the writing around that topic is so gotdamn convoluted that I haven’t been able to draw coherent parallels about it yet.
