'Grimm' season 4 spoilers: Love triangle gone deadly in episode 15 'Double Date'

Juliette Silverton as a Hexenbiest in Grimm Season 4.

Love ends brutally in the new installment of "Grimm." Episode 15 of the series "Double Date" will show Portland Police Department's finest Nick and Hank get to the bottom of a "one night stand turned deadly." A man was entangled in a "bizarre" love triangle that took his life, and it is up to the duo to capture the perpetrators of the heinous crime. 

But it looks like they will be getting help from Wu in this one. It's not surprising though. Wu always rallies around helping the two solve crimes.

"He's very enthusiastic, which I think we kind of discovered as we went," co-showrunner David Greenwalt told Zap2it about Wu. "He's almost like a kid. He's found his niche in life." 

Elsewhere, Captain Renard is suffering chronic episodes of phantom bleeding and decides to get help from Monroe and Rosalee. The captain already has so many things to deal with but this might just be the most game-changing one. 

"The bullet wounds are residual from being saved. Like everything on the show, it's not without consequence," Sasha Roiz, who plays Captain Renard in the series, told Zap2it. "I think it's something very dark that comes back with him. ... His brush with death certainly brought something back." 

Also, tables turn and Adalind gets the upper hand after stumbling upon a big discovery. Meanwhile, a big change is coming to Juliette and Nick's relationship. According to the synopsis for episode 15, Juliette has "a big decision" to make and it involves a change of course in her romance with the police detective. 

"Double Date" should show off some crossbow duels, resolutions and possibly more questions. Besides, the season is far from its culmination. Season 4 episode 15 of "Grimm" season 4 will be aired on March 27.
