According to this interview with David Greenwalt, the first one. The person we saw is Juliette in that she’s in the body of the person we’ve always known. But she’s also not Juliette in the sense that she’s been completely broken down into someone who doesn’t relate to Juliette at all, who sees Juliette as someone who is dead. She has all of Juliette’s memories, but not the emotions attached to them.
This kind of makes sense, actually, as Juliette was already losing herself more and more by the end of season 4. It sounds like she went through some pretty traumatic things in the few episodes she was missing, that have completely changed her personality as well as how she sees herself and the people who used to be important to her.
So I guess we’ll see to what extent that is true and whether it’s permanent!
