I love the symbolism of what the bullet that Olivia has been carrying for the last few episodes and how it factored into the plot in a big way in The Human Kind. The bullet literally saves her life and in the end is what's saves Peter's life now that Olivia was able to bring him back and give up the tech. Also, Jill Scott did a great job as Simone. I don't think we will see the character from here on out, but it would be cool to see if there was a bigger plan that she plays in the demise of the Observers since she can see the future in a way. But with Peter now at a disadvantage of foresight in killing Windmark, maybe it's her ability the Human resistance will come to rely on and use to their advantage.
