Grimm is a drama series follows a descendant of the Grimm line, Nick Burkhardt, as he deals with being a cop, and trying not to expose his secret as a Grimm. In modern day Portland, Oregon, a police detective inherits the ability to see supernatural creatures. In season 2, Nick learns that his mother has come back, to save him. Juliette is still in her coma from the spell that Adalind put her under, while Monroe and Rosalee work against the clock to try to wake her up.
Nick's fate in "Goodnight, Sweet Grimm" might have become obvious in the final minutes of the finale, but watching those suspicions play out didn't lessen the weight of it. They only made it more exciting.
