John Fawcett has said that Paul’s death is not only a turning point in the series, but also a “driving factor” for Sarah, so I do think that it’s going to have an impact on the rest of the season. Especially because, for as much as we got answers, there’s still a lot left to be explored with the truth behind the STD being brought out into the open, and the fact that we don’t know for sure whether Coady and Rudy are dead is pretty glaring, IMO.
I don’t really know if I can say how I think Sarah might take it? I feel like, because they spent so much time (after S1) putting Paul and Sarah almost at opposite ends of the spectrum, and keeping Paul as a really ambiguous character (though I personally always believed in him), she might not even know how to feel about it herself? In a perfect world, I’d like to see her dealing with the fact that he admitted, in a roundabout way or not, that he loved her,
but in a perfect world, Paul wouldn’t be dead right now. But she also has other, more pressing matters to deal with, so I wouldn’t be surprised if they didn’t dwell too heavily on it.
It’s hard for me to say whether Sarah loved Paul, definitively. I loved them together, and wanted to see them end up together, so there’s always going to be a part of me that says yes. Logically, though, I feel like, because of what they went through together–not just him always helping her, but her having to try and figure out for herself whose side he was on, and him doing the things he had to do that didn’t paint him in the best of lights–and because of who Sarah is as a person, she wasn’t there quite yet. I truly believe that she could have been, though, given time, and it breaks my heart that they’ll never get that time to really be with each other.
For me, I do definitely feel like she cared about him, though. When she told him to open the gate because she wasn’t leaving without him… Coming from her, especially given the way she’d treated him lately, that said a whole hell of a lot, I feel.
