That is *implied*, but my point is that nothing is ever learned about who they were or why their lives mattered, even though there are repeated vague mentions of the horrible things they had to do, how we don't know what Fiona was *really* like, etc. Why include these remarks in the show if an explanation - or, at least, an elucidation - will never manifest in the show?
What I really should be getting at is that Amy is in no way relevant to any of the plots of this season. None of the antagonists care about her or even know her name - all they want is the photographs, which she may or may not have. They assume that she has them and so want to find her solely because she is the person most likely to know where the photographs are. At no point does she contribute anything that Frank or Curtis could not have done on their own (googling "Schultz", googling [Russian name]).
Her role in the season, as a whole, can be reduced to the phrase "hiding in a room". She hides in the motel room. She hides in the police station. Then, she goes to New York, and hides in Madani's apartment. Then, she hides in the trailer. Then, sick of the trailer and bitter, she decides to hide with her old friend. When her old friend betrays her, she hides in a closet. Then, she returns to hiding in the trailer. Then, she hides in the Mennonite's hotel until Frank can get there to kill the Mennonite. Yet, in none of these circumstances is keeping her alive or killing her an immediate concern for either the protagonists or the antagonists. Her primary function in the story could be replaced by a flash drive. In fact, half the time, she doesn't even have the photographs on her person, so her role would actually be *better* substantiated by a flash drive.
