Exploding Jockey Head!

Yes looks like some kind of Worm well the Eel/Snake type Organism is jumping out of the head of the Jockey. This must raise a number of questions... Are the Jockey suits really just Hosts for that lifeform, like they are using crew members bodies for hosts? Does this Organism get hunted down in the Cargo Bay and what the crew are looking for with the Flammers, and does it escape and get to hunt down Shaw?

Im gettin the idea from the ampules, that there are alot of different nasty Big and small lifeforms. Perhaps the engineer has a Noahs Ark of sorts?

Yes yes yes I love all the theories, that's why i love this movie already!!!!

Notice how David doesn't look startled.

Sorry....exploding head is already up...locking
