This Friday will mark the return of NBC's "Grimm" from its winter recess, and it promises to start the New Year with love sparks and horror.

The upcoming episode, which is titled "Red Menace," will be interesting as Hank will make a move on his physical therapist, Zuri Ellis, who is played by guest star Sharon Leal of "Hellcats." There's a good chance that the therapy sessions get very physical between the two, revealed the series co-creator James Kouf to TVLine.

"He gets involved in something that involves a loved one of hers very dearly, and they sure look like they're falling for one another, but you never know," said Kouf.

"Yeah, she's the one who helps him get back on his foot," added co-creator David Greenwalt.

This week's episode "Red Menace" also finds Nick and his partner investigating a shady Wesen healer, while in the meantime, Renard will finally track down Adalind to give her a stern warning. Plus, the long awaited reunion between Captain Renard and Adalind will finally take place, reveals DreadCentral.com.

A promo video also shows Juliette kicking butt in a fight scene and Adalind delivering a baby.

According to KsiteTV.com, an official synopsis reads:

"A Wesen with a unique ability is at the center of a revenge fueled investigation. Nick (David Giuntoli) and Hank (Russell Hornsby) investigate a Wesen -'healer' whose ability holds risks that far outweigh its rewards. Meanwhile, Juliette (Bitsie Tulloch) takes in a friend when domestic issues escalate and Hank makes a move on his physical therapist Zuri (guest star Sharon Leal). Elsewhere, Captain Renard (Sasha Roiz) finally tracks down Adalind (Claire Coffee) and has a stern warning for her. Silas Weir Mitchell, Bree Turner and Reggie Lee also star."

"Grimm" S3E9 is scheduled to air on Friday, Jan. 3, 2014 at 9 p.m. EST. Watch a preview below.
