So close to the big reveal. So it appears Two and it sounded like Four, I think, were planning to kill either One, Three or Six. And Five may have known about it prior to the memory wipe since she was the one who planted the recording device. I'm starting to wonder whether
@REBerg is right and that Five really is the culprit. It would be a good twist. But I think more likely if she is responsible for the memory wipe then she did it to save whoever Two and Four were going to kill.
But it might be that Five hadn't listened to the device prior to the memory wipe, which would mean this is the first she knows of it. If that's the case, then the "traitor" is likely whoever "He" is that they were going to knock off.
I would have thought Android would have invented some way of protecting herself from getting zapped. She must be getting tired of it by now.
The person at the end who zaps Android, it just doesn't make sense that suddenly the "traitor" makes their move after all this time with seemingly no reason to do so. Two possibilities come to mind. Five is getting Android out of the way so that she can confront Two and Four about what she heard on the radio, and is planning to go about it in a surprisingly uncharacteristic manner, or the scientists messed with Two's mind and she's subconsciously turned against them.
Anyway, guess we will only have one week to wait before knowing the answer.
