The black goo spore in Alien: Covenant

This was a reply to a comment thread in YouTube discussing the effects of black goo.

The black goo reacts differently depending on what any of the other reactants are. Not just heat, but also air (+air pressure), different other gases, water or other solubles, contact with David's finger, sprakling wine, ingestion by Holloway, and contact with other Prometheus crew.

The process Holloway went through, is actually similar to what the Engineer in the opening went through, as both ingested black goo. As Holloway was "administered" much less of it and with champaigne, his 'decomposition', if you will, was a lot slower.

The "black goo" that gets into the Covenant cremember's ear, is no longer black goo, but either a spore, or a minuscule Alien life-form, as it can fly and target its flight path right into the ear of the poor colonist. I could count on the life-form being a back-goo-derived insectoid that acts as a very feeble wrapper of Alien protozoa that are to spread into a larger organism.
