Juliette starts remembering Nick in Season 4 , after the events that change her relationship to him and the truth about the Grimm world. Her memory is not a simple ā€œall at onceā€ return; it happens through a mix of supernatural effects, emotional triggers, and later storyline developments around her Hexenbiest transformation.

Where it happens

  • The big turning point is in Season 4, Episode 1, ā€œThanks for the Memories,ā€ when the show is already dealing with Nickā€™s life changes and Julietteā€™s situation shifts dramatically.
  • By later Season 4 episodes, Juliette is clearly aware of Nick and the truth she had been kept from, and the show treats this as part of her deeper transformation into Eve.

Simple answer

If you mean the moment she begins to remember Nick and their past , that process starts in Season 4 rather than in Season 2 or 3.

Episode context

  • Fans sometimes associate this with the earlier ā€œmemoryā€ storylines, but those are more about Nick hoping Juliette remembers him than it actually happening right then.
  • The real long-term reset in their relationship comes after Julietteā€™s Hexenbiest arc and the fallout from Nick revealing the Grimm world.

TL;DR

Julietteā€™s memory of Nick begins coming back in Season 4 , with the major shift tied to ā€œThanks for the Memoriesā€ and the episodes that follow.
