'Grimm' finale sneak peak: Has Juliette lost her mind?

May 16, 2013 at 1:52 PM ET

Although it feels like we JUST got our "Grimm" back, the season finale is really upon us. It would be easy to get lost in the sadness a Grimm-less summer, so it's especially great to have this exclusive sneak peak to feast on ahead of Tuesday's finale.

It's a scene between Nick and his not-quite fiancee Juliette, where she seems to be confronting him on the whole Nick-is-a-Grimm thing.

"Well, I now know why you couldn't tell me everything," she starts off.

Calmly, Nick replies, "I wanted to tell you. I just didn't know how. I was afraid for you to see a world that I didn't fully understand and now I'm afraid to push you into a world you're not prepared for."

"It's not as if you were prepared for it," Juliette responds. "And at least I know I'm OK. I haven't lost my mind."

Except the way she says, "I haven't lost my mind"? It makes a person think SHE HAS TOTALLY LOST HER MIND.

Here's what we know: For some reason, Nick really loves Juliette. Juliette has been spending the past few episodes trying to A) piece together the details of her last lucid days as a doting girlfriend and almost-fiancee to Nick, and B) get all Wesen-induced weirdness out of her head.

So maybe she is just saying, "Hey, I get it now. And we can be together," or maybe she's saying that and she's giving us a little clue that this whole experience has left her a touch loony. (Not that we could blame her.) For Nick's sake, he might be better off without her. For the sake of keeping things interesting -- bring on the crazy.

Tune in to the season finale of "Grimm" Tuesday at 10 p.m. on NBC.
