So the writers and producers did say someone on Nicks side is going to betray him. Could it be Trubel?

You mean besides Renard’s epic betrayal? Knowing these writers, it could be anyone. But of everyone, the three most likely candidates for me are:

Adalind – I find her most likely out of them because although she may love Nick (or think she loves him, it could still be magic weirdness), she also has two small children that she will always put before anything or anyone else. They’ve proven to be her pressure point in the past, and they could be again. If it comes down to Nick or her kids? No contest.

Juliette/Eve – I really don’t want this to be the case, but Julieve is still such an unknown in so many ways. Based on the end of last season and the start of this one, I want to think she’d come down on Nick’s side no matter what. But there’s a lot of pain, grief, and conflict swimming around in there. It’s just hard to know for sure.

Trubel – She seems to me the least likely to betray Nick, but…well, she kind of has before. She came to retrieve Juliette without talking to Nick about it on behalf of HW at the end of season four. She seems to do what they tell her to, for the most part. So what if HW told her to take Nick out? I’d like to think she’d balk, but we’ve seen less and less of her…they brainwashed Juliette’s personality away, who knows what they might have done to Trubel in all that off-screen time?

So Nick is becoming Renard. Okay, if he turns into a Zauberbiest I’m going to freak out. That would be such a poor, weak “twist.” Unfortunately its something I can definitely see happening with how lazy the Grimm Writers have been lately. Am I the only one whose worried about “side-effects?” Nick being a Grimm is enough. We don’t need a weird Grimm!Beist. Not to mention how annoying and recycled that plot-line would be or how it would crowd these last episodes. 8-P Just no. Please Grimm. No.

I find it unlikely for a couple of reasons:

  1. It wasn’t the twinning spell itself that turned Juliette into a Hexenbiest. It was a side-effect of the ritual they did later to return Nick’s Grimm abilities.
  2. Nick’s blood is anathema to Hexenbiests. It literally banishes Hexenbiest powers, presumably Zauberbiest powers as well. Adalind and Juliette are immune to the effects, but there’s no reason to think Renard would be. So it’s likely Renard’s powers couldn’t take root or “live” in Nick’s body once he’s returned to his true form.

That being said, Nick–possibly Grimms in general but especially Nick–tends to absorb some of the traits of any magic he encounters. When he was attacked by the Jinnamuru Xunte, he developed super hearing after just a few hours of blindness.

And when Baron Samedi subjected him to the Dämmerzustand, he gained super strength (at least temporarily), superhuman stamina, that weird “stoneform” thing he used to do occasionally, and the ability to go long stretches without needing to breathe.

So it’s possible that his body would just absorb the Zauberbiest powers like it absorbs every other semi-useful trait or ability it comes into contact with. We’ll just have to wait and see!
