Soemthing that goes overlooked with this episode, and you can see it at the end, is how much this impacted Casey. He's always been that guy when it comes to his job and the country, and to find out that his own side is the one that created such a monster and the betrayal of covering it up. He very much looks like he is wrestling with that conflict in his head while he putting away the pod.
I was just about to type this but I'll put it here. A guy like Casey is paid to follow orders. Zero emotions no matter who it is usually. For him to make that move showed his character development and showed them that he actually gave a shit about that entire group. I wise we could've had 10 or so seasons of this show. Very underrated in my astute opinion. They all played their parts to perfection. I'm thankful for this show and added it to my yearly rotation of shows I watch.
I'm not completely surprised with this news. If it wasn't the Intersect that messed him up, it might have been jealousy over the fact that the first woman he loved chose his partner/best friend.
Was obvious volkoff was going to be agent x when they went to England and found the place he grew up because how many Russians do you know have an English accent
