Let us not forget that the Mayor of Portland is asking Renard for help. This could lead the viewers to believe that Portland has a Wesen mayor. That might be an entirely different story to go with and would bring its own drama, not new to the show.
Renard is likely to be spending time on camera in that situation while we get to learn more about Eve and what her role is in the show since Juliette “vanished”. Since Trubel is back, there will be something to talk about there as the gang tries to figure out the scope of the Wesen uprising.
If you are not paying attention, there could be places throughout this season that get confusing. Just keep up on the episodes and all of the story will unfold nicely. If you need help, there are plenty of recaps and spoilers posted online.
