Viewers were already warned of Juliette's (Bitsie Tulloch) possible death earlier on in season 4 but will her actual death (if it indeed happen) push Nick (David Giuntolli) to the edge in "Grimm" season 5?
Although he was hell-bent on taking revenge on his ex-girlfriend in the finale, when his chance came, he couldn't do it. If Juliette, in turn, was ready to finish the job that Nick couldn't finish, we will never know because Trubel (Jacqueline Toboni) was able to stop her from murdering Nick.
Perhaps she had to do it, but as Juliette lay dying in Nick's arms, the mysterious Wesen FBI agent arrived at the house and ordered some men to "get her". Whether she was referring to Trubel or Juliette, fans will have to wait until "Grimm" season 5 to find out.
Did Trubel betray Nick by agreeing to work with Agent Chavez who had been hounding her since the beginning of the fourth season? Will her betrayal make her another person in Nick's list of people to get revenge on?
Showrunner James Kouf, however, thinks Nick will understand what Trubel did for him. After all, he did tell everyone of this friends that they should kill Juliette when they decided to storm the Royal's safehouse.
"He's gotta know, being a Grimm, that she had no choice if he were to survive," he told TV Line. He won't be very happy with it though.
"All the episodes are him, grieving. It's 12 episodes of him, alone in a room, feeling bad," co-producer David Greenwalt joked, with Kouf adding that he has to do that while working out all the "unsolved mysteries" around him.
Who could be the next big bad now? Especially with Juliette truly dead, the King thrown overboard a helicopter (thanks to Meisner and a very powerful Diana) and Adalind's power gone?
If Trubel does end up becoming Nick's enemy in "Grimm" season 5, it would be interesting to see a Grimm VS Grimm fight between them. Catch the next season later this Fall.
