Well, I only posted a single link, which I'm going to assume was the one that worked.

You said,

Either past blueverse plot of "he's the man who's going to kill me" has been dropped

which isn't so. The drawing of the person that was to kill her, looked like Walter. Which is what happened. The person that was to kill her was Walter and he did kill her; brought her back, but killed her. That was my theory when I looked the picture up. If you read that article that I linked to, it states the same thing, so my theory was correct.

And I'm fairly certain that Henriette DID say something along the lines of sometime in 2016 was the last time she SAW her parents, not that they were dead. Which was shown half true with Peter in the amber. And I think it is safe to assume that Olivia is also not dead. And why would she? The "the man who's going to kill me" has already happened, in the Season 4 finale.

The point I'm trying to make is, Olivia is alive in 2036. If they don't throw in something else.
