I agree that Adalind has become an unfun villain. I really like Claire Coffee, and when Adalind had her powers taken away, I had a lot of hope for the character. But I think all the baby/royal stuff kind of ruined her. I would have liked to see her flailing about life without powers and then reluctantly having to help Nick - when her character was vulnerable, I liked her more.
I am liking Juliet a lot more this season too - I think in part because Bitsie Tulloch has had more to do so there's not such a flat character to deal with. I am still baffled beyond belief why a vet doesn't own a pet, and why they've never brought her in more regarding the animal nature of wesen. Occasionally they do, but it's just a little here and there - I think she could be used in a better way.
I was so mad when Tommy Howell shot Renard I was gleeful when his head tumbled down the stairs. And I love him lol. But you don't shoot my captain!
I think I'm most interested in seeing what Wu makes of everything. Pissed off Wu could be really intriguing - just think of the sarcastic comments!
