Nick Burkhardt should swear off hexenbiests once and for all. He may be a Grimm, but dating members of the supernatural community has brought him nothing but heartache.

When Grimm returns this fall, Adalind (Claire Coffee) and Eve/Juliette (Bitsie Tulloch) will turn Nick's (David Giuntoli) love life upside down. With the former wearing Renard's (Sasha Roiz) ring and the latter reverting to her former self, the monster hunter will have a difficult choice to make.

On the one hand, Juliette was once the Rosalee (Bree Turner) to Nick's Monroe (Silas Weir Mitchell). Their happy life was upturned by the vet's newfound hexienbiest powers, and the situation only become worse when she liberated his mother's head from her shoulders and attempted to put him six feet under as well.

In the wake of "Beginning of the End," David Giuntoli dished on the former couple's chances.

"[He's] gotta be thinking, "Does Juliette know she killed my mother, when she was Eve?" And who is actually responsible for that death? If it was Juliette, Nick couldn't forgive her," the actor explained to TV Line. "If it happened as a side effect from Juliette becoming Adalind-which she was trying to do for Nick's benefit-then I guess he would have to forgive her. So all that is yet to be discovered."

Adalind's character arc, meanwhile, started on the opposite end of the spectrum. A devilish hexienbiest with control problems, Ms. Scahde cooled her heels once her powers were locked away. Renard, their diabolical daughter, and her returning supernatural abilities now stand between Nick and the life they were trying to build.

According to TV Line, this fall we will "finally get an answer to the question, "Who will Nick choose - Adalind or newly re-Juliette'd Eve?"

So, how will Nick chose? Sound off in the poll below!

Grimm will return to NBC this fall.
