This almost definitely confirms my theory from episode 2: the hive is 100% compliant with what anybody wants. I’m guessing the other few survivors will figure this out soon and it’s going to be a huge mess.

Also I think the hive is being coy about it. They say they’d do anything so Carol to be happy but once again I’m pretty sure they also have a ‘biological imperative’ to do what they’re told to do no matter what. Maybe that was intentional so the aliens that created this code can just walk into earth and instantly take control without any resistance.
