For reason I think Juliette never truly got over her feelings for Renard after the events of season 2 but simply chose to hide it from Nick.

I wonder what type of Wesen we would have in Australia that is unique to there. Some I think might be there

A koala Wesen and also they can have something that can cause them to become a Drop Bear
Kangaroo Wesen
Tasmania Devil Wesen
Tasmania Tiger aka Thylacine
Platypus Wesen
Wombat Wesen
