That interrogation scene, that was Shaw grieving. Reese is right, it doesn’t look like anyone else’s grief. She’s angry, not sad. She’s angry that Root’s dead, but it’s not a simulation. She’s angry that the Machine sent them after a half-assed assassination attempt instead of giving them something they can use to fight Samaritan or find Harold. Above all, she seems angry that she can’t be anything but angry.
“I’m angry that you have people you can love and you chose to sign their death warrants.”
There are two parts of this that I think really stand out:
/People you /can/ love./ She’s angry that she couldn’t love Root, at least not in the same way that Root loved her. She cared, and Root knew in some way. Still, Shaw’s grief manifests as anger against something she can control, or wishes she could (perhaps seriously for the first time in her life, since it doesn’t generally seem that it bothers her much otherwise): her PD.
/You /chose/ to sign their death warrants./ Shaw never had a choice. She wasn’t even /there/, and you can bet that she’s angry about it. She’s been stuck in simulations for months, and now she’s used to replaying the same scenarios over and over again, looking for a way to do things differently, and she’s angry that this time, despite months of what could be considered practice, she’s still failed.
This is Sameen Shaw’s grief. It doesn’t look like anyone else’s, but damn if it doesn’t make me ten times more sad.
