No idea. Anyways here's the article for those who are curious: http://www.denofgeek.com/us/movies/alien/262464/alien-covenant-michael-fassbender-on-playing-two-roles-david-shaw-s-relationship-10-years-later
I think it's safe to say Fassbender probably said more than Ridley Scott would have liked. He's still very fond of Shaw. Wouldn't surprise me though if he did something to her to prolong her life. Splice her DNA with Engineer DNA or something to that affect.
