Juliette’s memory returns:

Juliette finally remembers how she feels about Nick. But she’s not sure if it’s a good thing or a bad thing.

Can he talk her into telling Nick she has all her memories back? Or will the big favor she asks of Monroe scare her away again?

Juliette explores the trailer:

Monroe takes Juliette to aunt Marie’s trailer. Along with it comes her memory of when Nick tried to confess his Grimm life to her the first time. Looking around the trailer only seems to bring up more questions than answers for Juliette!
