When "Grimm" season 4 returns on NBC with its 14th episode titled "Bad Luck" on 20 March, Friday, at 8pm, the sequence between Nick Burkhardt (David Giuntoli), Juliette Silverton (Bitsie Tulloch) and Adalind Schade (Claire Coffee) will take a new turn.

The Supernatural drama will pick up from its fall finale, where in Schade informs Silverton that she is pregnant and Burkhardt finds out that his lady love is a hexenbiest.

While the detective tries to find an answer about his beauty turning into a beast, he will receive an advice from a visitor, stated the official synopsis of mid-season premiere episode.

Meanwhile, the official trailer of "Bad Luck" shows Henrietta (Garcelle Beauvais) advising Burkhardt to kill Silverton for his safety.

Even the showrunners David Greenwalt and Jim Kouf teased that Silverton might turn out to be the new villian in "Grimm" season 4.

"We warned and warned and warned that there would be side effects if she did this thing, if she changed into Adalind and slept with Nick. There have been side effects," they told Zap2it.

Meanwhile, Tulloch revealed that her character in "Grimm" season 4 will not just be a potent force but a serious threat to Burkhardt.

On the other hand, Henrietta will make some shocking revelations to Schade and the latter may use the information to make a move against Burkhardt and Silverton in the mid-season premiere episode.

However, "Grimm" fans will have to wait until 20 March, Friday, to know more about the storyline of Burkhardt, Silverton and Schade in episode 14 titled "Bad Luck".
