Executive producers Jim Kouf and David Greenwalt talked to TV Guide about the upcoming episodes and what fans can expect in the final season.

Talking about the love triangle, Greenwalt stated that the new season will see the resolution of this and it will be cleared who will be with who.

"It all has to get resolved one way or another, either through violence or violence. It's been a six year journey for these characters. It's more important that they come into their own personal, individual power -- Adalind, Eve/Juliette and Nick. There will be resolution as well of who loves who and who is actually going to be with who," Greenwalt said.

Nick and Renard will have a showdown and Greenwalt shared about the upcoming clash.

Both Renard and Nick want to kill each other, and according to the executive producer, the first three installments of this season will define how this clash will unfold.

"We've known that it had to come to a head from the very beginning. The first season Renard was -- I don't want to use the word evil or bad -- kind of cunning. Then he kind of came around...Then Renard screwed everybody by running for Mayor. Renard really wants to get Nick, literally kill him, and Nick really wants to get Renard. These first three episodes we'll see exactly how that unfolds."
