Alien: Covenant, what did Walter do with the human embryo at the beginning of the movie?

He discarded it in a biohazard container

Yes, it died so he threw it out...

Saved it from a much worse fate!

Haha thanks!! I completely forgot about that

Wasn't this right before all Hell broke loose?   Seems like he just discarded the embryo before he had to rush to figure out what was going on with the ship.  Maybe he was taking the embryo to the lab for a little QA.

Think about this. Why did David regurgitate the embryo containers. If he had full access to the ship through MUTHER, why bother. I believe Walter was instructed to carry them. Could the flute playng exercise be so much more. Think about it. How and when did alien DNA transmit over to the embryo containers?

Is Walter dead? He seemed to have some regenerating tech(maybe in  1 week or 2, his hand would have grown back?)...... Could David 'kill' another synth? Maybe he just left him 'turned off'. 

I'd like to see Walter make a comeback.

Are there other Engineer cities on the planet...can't believe there is only one!?

Seemed very clear after two viewings it didn't survive and tossing the bio-hazard container confirmed that.
