The age of miracles may be past, but Grimm pulled one out in its 100th episode on Friday.
Monroe (Silas Weir Mitchell) looked like a goner after coming down with blood poisoning from a Wesen bite on his arm, but before the Blutbad bid his final adieu, he suddenly, miraculously recovered thanks to Nick (David Giuntoli) accidentally touching his friend's arm with a plain-looking stick. This clearly was no ordinary piece of wood though, which explains why during the Crusades, seven Grimm knights hid it in a trunk in some German catacombs.
Meanwhile, Capt. Renard (Sasha Roiz) discovered that the Black Claw organization was behind the assassination of mayoral candidate Andrew Dixon (Michael Sheets) because they want Renard to run instead. Earlier at the Spice Shop, Adalind's (Claire Coffee) powers returned in a gnarly way while defending Rosalee (Bree Turner) from her ex, Tony (Joseph Kathrein). 
Co-creators Jim Kouf and David Greenwalt chatted with The Hollywood Reporter about that stick, rotten ex-boyfriends and the trouble that lies ahead.
What can you say about the miraculous healing stick and what we'll be seeing next? Is it based on anything?
Jim Kouf: The answer is in real history. 
Besides being healed, will Monroe have any other side effects from the stick? 
David Greenwalt: We don't know yet. There are other things that will happen because of it, but not necessarily to him. 
Speaking of strange effects, Adalind's powers seem to be back. Is this a good or bad development? 
Kouf: It's going to be a pretty mixed bag, but the thing you fear the most frequently come unto you. And she's still afraid of what will happen to her relationship with Nick? What will happen to her relationship with her son? Will Nick in fact try to kill her if she's a Hexenbiest again? So it brings up all kinds of nice, shiny problems. 
Nick can't catch a break with his love life! Does this mean we already have a potential rift between the new lovers?
Kouf: Oh, yeah. 
Greenwalt: You may remember that in the pilot, Aunt Marie said to Nick, "Juliette is perfect for you. You have to leave her." And Aunt Marie's point of view was that it was impossible to be a Grimm and have a happy, loving relationship. Now his mother, when she returned, said that after living alone as a gunslinger person, she encouraged him to have a relationship. It's pretty hard as a Grimm because they came to their house many times. Really bad things happened right in that house. 
Adalind's powers came out because of Rosalee's ex-boyfriend, Tony. Is that the last we'll see of him? 
Greenwalt: Nope. We like him. He's a really great actor and he's a really creepy character. 
What type of Wesen is Tony? I couldn't catch it when he woged.
Kouf: Kackenkopf
Greenwalt: It literally means, "crap head," so he's a dung beetle because he's such a crap head. 
Kouf: It's the description of a rotten boyfriend. 
On the flip side, our golden boy Renard is being courted to run for mayor (and with an Obama-ized campaign poster!)
Greenwalt: It's a hell of a journey coming up. 
Kouf: He's going to make a lot of people angry. 
Will he be wooed to the dark side? Will he become a double agent? 
Greenwalt: Not so much a double agent. As Shakespeare said, "Neither good nor bad, but thinking makes it so." He is the guy whom nothing is either good or bad to. He never chooses sides unless it's his own side. There is some really wild stuff coming to Renard — and to Nick, too. 
What can we expect from Hadrian's Wall and the Black Claw? Are we gearing up for big fight?
Greenwalt: We are. They've got to come to terms and grips with each other, and it may not go so beautifully for the side you think should win. 
Hadrian's Wall just shuffled off Trubel (Jacqueline Toboni) to another country quickly. When will she be back? 
Greenwalt: She's coming back for many of the last episodes. She's been away fighting bad guys all over the world, but now she's back because she's needed here in Portland so much. You'll be seeing her toward the end of the season quite a bit. 
Let's talk all about Eve (Bitsie Tulloch): Will we learn more about what Hadrian's Wall did to her and what the extent of her powers are? 
Kouf: We'll learn all of that for sure. And she's an extra-specially strong Hexenbiest. A long time ago, I think it was Rosalee who said that the Hexenbiest that are made, not born are even worse than regular Hexenbiests. Or stronger. 
Grimm airs Fridays at 9 p.m. on NBC.
