Corrected entry: After the drone has killed Victoria, as it enters the house, if you look at the bottom of the screen, you can see the device moving the drone into the house. This piece is not there on any other drone in the movie. (01:10:35)

Correction: The "device" at the bottom of the drone are the pipes or tubes that have just been disconnected from the maintenance device - we saw them being pulled out seconds earlier.
