Shaw's back - Whats that?!

There is a pretty big discussion about that here:

http://www.alien-covenant.com/topic/43915

it's definitely NOT a xenomorph tail, so don't get that idea.

it could be one of two things:

1. spike coming out of her back. (transformation or neobirth)

2. reflection from the chair. (more famous option)

I thinks its the deacon from the end of prometheus. Because this looks definitely like a tentacle to me and the host of the deacon did have tentacles! 

Or this is the biomechanical shaw 

perhaps it is the end tail of a facehugger????

Davefried81 OT. SGT stripes and an ARCOM?

Never ceases to amaze me what many people (think they) see in images etc, just because they wanna see it...

Its like a mendela effect for movies and upcoming movies.

Its so obviously just the lightglows reflection on the chair it hurts.

Come on people, the thing on her back clearly isn't part of the hologram. I even saw a deacon in the clouds yesterday.
