So what has happened to Dr. Elizabeth Shaw??
My theories are:
She dies enroute to paradise.
She strands David on that planet cause he is what caused the destruction there. (Heading for parts unknown.)
David tricks her into getting impregnated.
She's the one in the pilot chair in the first Alien movie, and set the warning beacon.
Now she may not be in this one and show up I one of the other 2 cause she's made no comment or talked about it.
There is a 10 yr time period between Prometheus, and Covenant anything could have happened. I can't imagine there will be no explanation as to her whereabouts.
Would be cool to see a cryptic type message from here during the viral marketing about what happened like a audio/video type recording that we will see in the film.
