'Grimm' season 6 episode 2 spoilers: Nick makes a dangerous pact; EP promises to resolve Juliette–Nick–Adalind love triangle

Nick (David Giuntoli) makes a pact that could put his life in danger on the upcoming episode of NBC's supernatural drama "Grimm" season 6.

Titled "Trust Me Knot," this week's episode will bring up a lot of revelations. According to the official synopsis, Nick continues to be on the run, while Hank (Russell Hornsby) and Wu (Reggie Lee) work together in an effort to stop Renard (Sasha Roiz).

Back at the spice shop, Rosalee (Bree Turner) and Monroe (Silas Weir Mitchell) are tasked to look after Diana (guest star Hannah R. Loyd). The duo's adventure in babysitting takes a different turn when Diana surprises them by showing off her power. Elsewhere, Trubel (guest star Jacqueline Toboni) and Eve (Bitsie Tulloch) team up in an effort to solve the mystery behind the cloth found with the healing stick.

Last week's premiere picked up moments after the fifth season ended — with Bonaparte (Shaun Toub) found dead in Nick's loft after Renard murdered him. It turns out that Renard was actually being controlled by Diana, his 9-year old hexenbeist daughter, who didn't like how Bonaparte threatened her mother.

Diana appears to be getting more powerful as she grows older, and fans may be wondering how she'll react when she discovers that her mother, Adalind (Claire Coffee), is actually in love with Nick instead of Renard. Speaking with TV Guide, executive producer Jim Kouf talked about how the young hexenbeist thinks. "She's still a young girl. She goes with mom above anybody," he explained. "Whoever makes mom the happiest, whoever treats mom the best, is where her allegiance lies," Kouf added.

Meanwhile, Juliette (Bitsie Tulloch) is beginning to resurface, and that means bad news for Nick and Adalind. Co-executive producer David Greenwalt hints that the love triangle involving the characters will be resolved before the series wraps up.

"It all has to get resolved one way or another, either through violence or violence. It's been a six year journey for these characters... There will be resolution as well of who loves who and who is actually going to be with who," he previewed.

The sixth season of "Grimm" airs every Friday night at 8 p.m. ET on NBC.
