So I'm watching S4 finally and got to this episode and figured I would post here because I am so utterly confused.
Olivia is dead? Is that what September meant by looking into all futures and her having to die? The observers take over? I thought they were good 
It was just such a random episode. I wonder how much of S5 will play into this storyline. |
We don't know what happened to Olivia in 2036, that's one of the big questions of season five. She could be dead, but other things could have happened to her between the present day and what we saw in Letters of Transit.
Yes, the observers will take over, and yes, you're not the only one who thought that they were good, if not good, certainly not those creatures that we saw in this episode. It was so random
This episode was random in the context of season four, but they'll use it to be an important part of S5; they say S5 won't completely take place in 2036, but we'll see that future again.
