David 8's Lab Tools and Experiments (enhanced)

Ingeniero
MemberPraetorianAugust 08, 2017David 8 prepares a solution while narrating his message to Weyland-Yutani Corporation in the Advent short film. Advent is defined as the arrival of a notable person, thing, or event and is also used to describe the coming resurrected savior.
In Advent, I'm sure everyone noticed David 8 harvesting some kind of egg with metal tong-like tools.
An image flashes that gives the impression that the procedure is performed on the cross-section of the neomorph head.
The black goo solution made in the segment is squirted into a recess and then David 8 recovers tissue and egg-shaped material.
This is in the area where the pituitary gland may be in the neomorph.
The flash of images shows what I believe to be a cross-section of a neomorph head and Dr. Shaw's torso where David 8 is recovering material (eggs?).
Dr. Elizabeth Shaw
The below image from Advent appears to be the mutation growth on the back of Dr. Shaw's head.
Is the above image a close up of Dr. Shaw's mutation? See below.
Below is the other site that David 8 is harvesting eggs from that may be Dr. Shaw's corpse treated with his solution of black goo.
Is the above image a close up of Dr. Shaw's open torso violated by David 8 with black goo?
Had David 8 performed this ancient ritual on Dr. Shaw?
