The upcoming "Grimm" Season 6 episode 4 will feature Nick's return to detective work after he foiled Renard's plans to keep him behind bars. Titled "El Cuegle" the said episode will also include what appears to be Renard's hallucinations that involved some of the men that he killed in previous episodes.

A teaser clip posted on Spoilers Guide featured the police captain receiving an unexpected visit from Meisner's (Damien Puckler) ghost. Standing inside Renard's bedroom, the deceased leader of Portland's Hadrian Wall warned the former mayor that he was wrong in choosing Black Claw.

Despite Renard's disbelief over Meisner's appearance, he approached the said character to find out whether he was seeing a vision or a ghost. After touching Meisner's chest, the deceased character assured the police captain that he is indeed standing inside Renard's bedroom.

Meanwhile, another preview clip posted on the same news site revealed an interesting information about Monroe (Silas Weir Mitchell) and Rosalee's (Bree Turner) soon-to-be-born baby. After Diana approached the pregnant Rosalee, she mentioned that the expectant mother is carrying more than on baby.

The revelation took Monroe and Rosalee by surprise, as Hank conveyed his congratulations to the couple. However, when asked how many babies she sees, Diana can only state that there will be more than one baby.

Recently, showrunner David Greenwalt shared his thoughts about Rosalee's pregnancy. In an interview with TV Guide, he teased that viewers might see several babies in an upcoming episode. He stated, "You can expect to see a baker's dozen babies sometime in the later part of the season."

"Grimm" Season 6 episode 4 will be released on Jan. 27, Friday, on NBC. Watch a promo clip for the said episode below:
