Any Grimm fans (Klaatu, etc.) out there?
What do you all foresee for Season 4?
How will Nick begin to regain his powers? Will he have other powers that will become available? How will Trubel fit in with his recovery? How will Nick & Juliette repair the damage?
Will Renard survive? How will he be brought back to health?
Where will Adalind search for Diana? How will Diana's powers develop under the care of Nick's mom?
Will Nick & Hank ever let Wu in on the fun..
Feel free to add possible plot lines..
I think the bigger question is about Renard. Is he dead?
Nick's mom kills as a reflex. Nick has to overcome an internal struggle not to be like his mom. I don't think Nick is a good enough actor to portray that inner struggle.
Poor Wu. Like the last one in on a joke.
I'm not crazy about the Trubel character, although the backstory on how the actress (or non-actress, really) got the part is interesting. Again, there's a DS9 parallel for me, when Jadzia Dax was replaced by Ezri Dax (another young brunette with short hair), a character who monopolized much of the first few episodes of Season 7 (Wesley Crusher Syndrome on early TNG, which then morphed into Seven of Nine Syndrome on Voyager).
Personally, I would have rather had some of the other characters fleshed out a lot more instead of bringing in a new one.
