This episode provided us with an opportunity to let Monroe do a little undercover detective work, something we always love to see him do. We also got to investigate the workings of another herd-based group of Wesen, similar to that of the Mellifers, or bee creatures, we got to know early last season. But whenever we have a number of Wesen together, we have to think about morphing them all and the logistics of being able to successfully achieve it both technically and financially. Our team at Bent Labs really did some great work this go-around. It was also a pleasure working with the many guest stars in this episode, especially Jonathan Scarfe (Reverend Lance B. Calvin) and Kristina Anapau who played his assistant Megan Marston.

Quill was an opportunity for us to pay some attention to the budding relationship between Monroe and Rosalee, aka Monrosalee as it has become affectionately known. And we thought, what better way to explore newfound love than by introducing a Wesen-specific plague that turns its victims into randy, rabid, contagious unfortunates? One of the toughest things about introducing an infectious disease was making sure it wouldn't raise a red flag in terms of the realistic implementation of quarantine, which is something we wanted to avoid. That's why the medical opinion of Dr. Harper (Sharon Sachs) was so crucial in this episode. By bringing her into the mix we were able to establish the curious nature of the disease.

"Bad Moon Rising" was a really big episode for the character of Hank Griffin. He finally learned the truth about all of the unexplainable things he has seen over the past year. We caught up with actor Russell Hornsby on set for some brief insight into what it was like portraying such a unique scenario.

Q: This was a really big moment for your character. How was it shooting such a pivotal time?

A: Shooting such a pivotal scene was taxing both physically and mentally. The blocking of the scene presented many logistical challenges (having to run with and hold Maddie take after take), which through filming a three-hour scene starts to wear your body down. Such an emotional scene involves a great deal of mental stamina to recreate fresh emotions take after take.

Q: Hank and Nick have a pretty close relationship, but do you think he could have been able to accept the truth if he didn't have his goddaughter present?

A: I do feel Hank would have been able to accept the truth about Nick being a Grimm, given his sensible nature as both a man and a police officer. With both his goddaughter and the impending danger present, Hank had no choice but to quickly accept his partner's true identity.

Q: When did you learn about Hank coming into the loop? And, were you worried at all about how long you were going to have to exist in such a delicate mental state?

A: No, I was not concerned about how long Hank would remain in such a delicate mental state. I trust the writers, who know where the story is going and how Hank's character impacts the story.

Q: Now that Hank knows what he knows do you feel it will affect his method of investigating?

A: It won't change his methodology, but it will enhance his awareness when recreating a crime scene. Always asking Nick the question "has this scene been tainted?"

Q: How about his partnership with Nick?

A: Now that Hank knows the truth about Nick, they will become better partners and develop a stronger bond as friends.
