I got the image of this bit appearing after the white room scene.
Just Shaw going into the chair and taking off. Cut to the Juggernaut 2 in space as it disappears into the distance.
The date on screen fast forwards and we see the Covenant coming into the screen.
Later during the flashback we see her getting out of the chair and fixing up David and stuff.
I miss Noomi. If we ever get some kind of reboot/remake/spin-off/whatever I'd love to see her return in another role.
