With everything that's happening to Nick right now (Juliette turning into a very bad Hexenbiest, finding out he has a baby with Adalind and Jack The Ripper killing off Wesens), Rosalee's decision to contact Trubel last episode seemed to be the best thing to do for everyone.
With the young Grimm coming back to Portland for the next "Grimm" season 4 episode, will Nick finally have all the help he needs to get things back to normal?
According to Entertainment Weekly, the last two episodes this week will most likely be "explosive" and up for "major cliffhangers".
Trubel already proved she has grown into a formidable Grimm. On the other hand, like Nick and his friends, the brooding youngster also has immense affection for Juliette. Will she be able to help in saving her and keep the Royals away from baby Diana at the same time?
Aside from Trubel's return, Dread Central also focused on the Jack the Ripper-like suspect. Despite figuring out that the killer is the same entity all for three centuries, Nick , Hank and Sgt. Wu are still somewhat clueless as to who he is today.
EW speculates that the killer could be Sean Renard, seeing as he's been having blackouts and waking up in odd places.
Meanwhile, the "Grimm" season 4 episode 21 trailer shows someone screaming with anguish. Could a major character die by the finale?
EW thinks either Kelly Burkhardt, Monroe or Rosalee could be the casualty. This could potentially put Nick on a warpath by the finale. This could also make Nick finally hate Juliette.
On the other hand, could this possible falling out between the former lovebirds trigger a closer relationship between Adalind and Nick? After all, they are about to have a son.
