First things first: Is Captain Renard really dead?
No solid answer came from the panel.
I would hope I get the powers back on some level.
Were changing the rules and not subscribing to the old-fashioned rules.
Fun fact: In an earlier version of the pilot, Juliette was a baker, not a vet.
So actress Bitsie Tulloch had some ideas about how she could be a badass baker.
Having been a fan ofBuffyandAngel, I thought I would kick some major butt.
I was imagining these scenes.
I got a trainer that summer [before season one].
I thought I was gonna throw muffins and sauce at everyone, Tulloch said.
And of course the vet experience made Juliette a unique asset once she joined the Wesen-aware Scooby Gang.
In September, October it starts getting graythats the perfect time.
Theres all this mist in the air.
Its what we call theGrimmlook.'
Another hint of whats to come from Greenwalt: Those keys first seen in the season-two premiere are back.
Therell be another key this year.
We will answer what those damn seven keys mean and what they lead to, he said.
Reggie Lee, who was welcomed onto the stage with chants of Wu Wu Wu Wu!
from the audience, said Sgt.
How would that work?
Sasha Roiz (Renard) wanted to know.
Lee then mimed a reverse version of Renards trademark shirt-ripping, anguished yell and all.
