In the upcoming "Grimm" Season 6, Adalind (Claire Coffee) is on a quest to save Nick's (David Guintoli) life by stopping her daughter Diana from killing him.

According to Game N Guide, Diana is a combination of a Hexenbiest and a Zauberbiest, being a child of Adalind and Renard (Sasha Roiz). This makes her a very powerful Wesen, and thus, she must use her powers wisely in order to not cause grave damage on anyone. Although she has showcased her incredible powers a lot during Season 5, everyone was shocked when they saw how she controlled Renard's body in order to kill Bonaparte.

Thus, due to her powers, Adalind has to convince Diana not to kill Nick in "Grimm" Season 6. Diana strongly dislikes the idea of Adalind with Nick since she wants her mother to stay with Renard. Like any other child, she wants to live in a complete home with a mother and a father, but unlike other children, she has the power to make this happen.

Diana even killed a few people just to ensure that her parents stay together, showing that she wouldn't let anything take her away from her goal of having a complete family. According to Ecumenical News, there is a possibility that Diana may intend to kill Nick in "Grimm" Season 6, given that Nick is a hindrance to her ideal family. Renard may support this and urge his daughter to push through with her plans. Fans will be interested to know to whom Diana will listen to.

Coffee revealed in an interview that Adalind wants to be "back with Nick" and "establish a family with him," ultimately attaining the happiness that she desires. In addition, she shares that Adalind believes that Nick is on "the right side." Adalind may not attain this goal that easily, given that Eve has remembered her true identity as Juliette and will want to win Nick back from her in "Grimm" Season 6.

With Diana being "more powerful than a Hexenbiest" and Juliette returning to Nick's life, it will be interesting to see if Adalind will succeed in her plans to be happy with Nick in "Grimm" Season 6.
