I think I have figured it out now.

It's not Nick Rosalee is going to kill but the Tybalt role inside Nick.

In Romeo and Juliet,  Romeo kills Tybalt. So I know Rosalee (Romeo) is going to say something devastating to Tybalt (Nick). Tybalt is the hot head who provokes the feud between the Montagues and Capulets. Rosalee is going to say something to Nick that stops him from continuing to provoke this Hexenbiest-Grimm feud. She is going to tell Nick something that will make  Nick give up his Tybalt role. When he is no longer Tybalt he is free to start another storyline. This time Nick will be Romeo and Adalind will be Juliet Capulet.

Rosalee and Monroe  switch with Nick and Adalind in the parts of Romeo and Juliet. They will pick up the story from where Romeo spends his wedding night with Juliet before he has to flee the city for killing Mercutio the next morning. Nick and Adalind will have a their first night together and then immedately after there will be an arrest warrant out for Nick for Juliette Silverton's death. I just don't know the timing. It may take all season for that storyline to play out. That may be the season finale when Nick has to run from the law for Juliette Silverton's death. But Rosalee should "kill" the Tybalt character in NIck first for this storyline to work.

And it makes sense in Hamlet, Hamlet dies before Laertes, in Romeo and Juliet, Romeo dies before Juliet. And since Nick is Hamlet and will be Romeo, and Adalind is already Laertes and will become Juliet, Nick will die first and then Adalind and the story will end. Maybe not the series, but the storyline will.
