Apart from a couple of minor production errors that took me out of the moment*, this was another good episode.
*1. When they were keeping the cell phone connection active, there was one point where Esther actually ended the call, complete with a beep sound effect to demonstrate the call ended. Meanwhile, Rex was still inside with his open and active phone.
2. Right after Jack explains that if you take away the Alpha plate the null field will be disabled, he pockets the plate disabling the field. But then he says "good luck" to Rex, who is just outside the field, and his lips move soundlessly as though the field were still active.
