'Grimm' season 6 spoilers, plot news: Nick and Adalind pairing is endgame?

Nick's (David Giuntoli) romantic ventures will be very complicated in "Grimm" season 6 especially with the possible return of his old love and a massive hurdle in a relationship he wants to pursue.

In the last season, the Grimm fought hard to get Adalind (Claire Coffee) and their son baby Kelly out of harm's way. He hasn't quite done that yet and will continue to do so in "Grimm" season 6.

Nick is determined to keep his family safe but as determined as him is Diana (Hannah R. Loyd), Adalind's powerful daughter with Renard (Sasha Roiz).

Diana is ready to kill anyone who gets in the way of her parents' love, which is nonexistent at the moment. It will be wise for Nick not to mess with her, considering the power she has.

But as what Giuntoli told TV Insider, his character is basically "in love" with Adalind and boosting that love is the fact that they have a kid. However, it is unclear if he will pursue her in "Grimm" season 6 or if he will be successful.

Although he badly wants to protect his family, Nick knows that Adalind's priority is the safety of her children. If it means staying with a man of unspeakable character like Renard, she will do so for their sake.

However, if Nick is truly head-over-heels for Adalind, he will make sure that the woman he loves is also safe. His pursuit should deepen his feelings for her in "Grimm" season 6.

Unfortunately, this won't be the only issue Nick will deal with, considering that Juliette (Bitsie Tulloch) appears to be slowly resurfacing from Eve's stone-cold façade.

Nick would not be too thrilled about taking her back though, especially if he gets the confirmation that it was purely Juliette (no influence of anything else) who knowingly killed his mother.

According to reports, "Grimm" season 6 might be the hit supernatural drama's last. If it will be, it will certainly be exciting to find out which between Adalind and Eve will be with Nick in the end.

"Grimm" season 6 premieres this Fall.
