I just re-watched the scene from two episodes ago: Simmons misses the guy's neck and got him on the cheek. I also thought on initial viewing that she got his neck.
Also, yeah, the controller scene seemed kind of silly.
Isn't standing there and looking menacing basically her entire role?
Also, I forgot how tough the Kree were portrayed the last couple times they were around, but they seem like chumps on this station.
